2.4.3 Installing a Mini Tower (MT) Model

Place the unit upright, on its feet without blocking air inlets.

2.5 Connecting Loads

The UPS has non-programmable and programmable outlets. Plug your critical equipment (such as computer, monitors, etc.) into the non-programmable outlets and your less-critical equipment (such as printers and other less-often used peripherals) into the programmable outlets. Refer to setting numbers 2 and 3 in Table 3-6 for programming instructions.

2.6 Connecting for Network Protection (Optional)

Protection from electrical surges to your computer network or telephone is provided on 2U and MT models. Use the network/fax/modem surge-protection ports on the rear panel. Connect the "IN" port to the line from the wall jack and the "OUT" port to your device port. Use of this feature is not required for proper operation of the UPS.

2.7 USB Connection

Basic monitoring of the PSI5 ^™ and unattended controlled shutdown of your computer in case of a power failure can be done using the Liebert Power Assist software via the USB port. Visit www. vertiv.com/ powerassist for additional information.

2.8 Emergency Power Off (EPO) Connection (Optional)

To comply with national and local wiring codes and regulations, the EPO connector internally disconnects all power sources to equipment connected to the UPS. The default operation is “active open” which means you must remove the factory-installed jumper and connect to external contacts that are normally closed but which open during a power-off event. The logic may be reversed in the Settings; see Configuring UPS with the Settings Menu on page 23. If you do not use the EPO connector, leave the factory-installed jumper in place and the default EPO settings in the Settings.

2.9 External Battery Cabinet Connection on 2U Models (Optional)

External battery cabinets provide longer battery run time for connected devices. Refer to Specifications on page 31, and Run Times on page 38, to select the appropriate model and quantity for your PSI5 model and applications. You can connect up to six battery cabinets to the 2U PSI5 models. LI, MT, and 1U models do not support external battery cabinets.

To connect an external battery pack:

1. Connect one end of the external battery cable to the UPS and one end to the battery cabinet as shown in Figure 2-6 on the facing page.
2. If connecting more than one external battery, connect one end of the external battery cable to the second connector on the battery cabinet, the connect the other end to the next battery cabinet as shown in Figure 2-6 on the facing page.

NOTE: After installation and initial startup, set the number of installed battery cabinets in the UPS Settings.

NOTE: When two or more external battery cabinets are used with PSI5-1100/2200/3000/5000 models, the UPS load rating is decreased by 20%.

To install the card:

1. Remove the two screws and protective cover on the rear panel network communications port.
2. Insert the card into the port and secure it with the screws. Refer to the documentation with the card or at the link above for cable connection and operation.

2.11 Connecting AC Input

CAUTION: For 1U and MT UPS models, to reduce the risk of fire, connect only to a circuit provided with 20A maximum branch circuit over current protection in accordance with the National Electrical Code, ANSI/NFPA 70 and the Canadian Electrical Code, Part I, C22.1.

Ensure that all the loads are first powered off. Connect to an input power supply/wall outlet that is properly protected by a circuit breaker in accordance with national and local electrical codes. The input receptacle must be grounded. See Specifications on page 31, for input cord rating. An external circuit breaker as described in Table 2-1 below is recommended.

Once the UPS is plugged into the wall outlet, it begins charging the battery.

NOTE: While every precaution has been taken to ensure that the battery is in good condition, Vertiv™ recommends plugging the UPS into AC input and to charge the battery for at least 12 hours prior to providing full backup time protection for any utility power abnormality.

Table 3-6 Setting Numbers and Options

SETTING NUMBER SETTING OPTIONS
01	Nominal voltage setting. Set the nominal system voltage to match the input voltage of the UPS. This setting affects the buck/boost/on-battery transfer points and sets the output voltage in Battery mode.For 120 VAC models:100 = 100VAC110 = 110VAC115 = 115VAC120 = 120VAC (default)125 = 125VACFor 208 VAC models200 = 200VAC208 = 208VAC (default)240 = 240VAC
02	Enable/Disable programmable outlets.ENA = Enable, programmable outlets are powered when running on battery per the time assigned in setting 3.DIS = Disable (default), programmable outlets are powered when running on battery until battery end of discharge.
03	Programmable outlets time limit with setting 2 enabled. Set a maximum time the programmable outlets are powered when running on battery. Setting a shorter time limit for programmable outlets extends the time the non-programmable outlets are powered when running on batteryO to 999 minutes (999 is default)
04	Enable/Disable site fault detection.ENA = Enable (default)DIS = Disable
05	Enable/Disable neutral grounding in battery modeENA = Enable (default)DIS = Disable
06	Battery backup time limit. Sets a maximum time to provide output when running on battery.O to 999 = minutes, selecting 0 (zero) sets a limit of 10 seconds.DIS = Disable Backup time depends on battery capacity (default)
07	Set the number of connected external battery cabinets. (available only on VRLA 2U models)O to 6 (0 is default)NOTE: For the Liebert PSI5-1100/2200/3000/5000: When using two or more external battery cabinets (EBCs) the UPS load rating will be decreased by 20%. The % load graph on the LCD automatically adjusts to reflect this derating.
08(11 on TAA models)	Set the Emergency Power Off (EPO) logic function.AO = Active Open (default)Activates Emergency Power Off when EPO connector pins are not jumpered (open).AC =Active CloseActivates Emergency Power Off when EPO connector pins are jumpered (closed).

SETTING NUMBER SETTING OPTIONS

09(12 on TAA models)	Set the sensitivity of acceptable input voltage quality. When distortion or disturbances are detected on the input voltage, the UPS protects the plugged-in equipment by switching to Battery mode. The lower the sensitivity setting, the less frequently the UPS switches to battery, but the more distortion and noise may be passed through to the plugged-in equipment. If you are using a poor quality input source such as a generator or step-wave source on which your equipment can fully operate, a lower sensitivity setting may provide longer battery life and run times.ST1 - High sensitivity (default). Provides the maximum protection. The transfer time is typically 4 to 6 ms, 10ms max.ST2 - Medium sensitivity. Provides medium protection. The transfer is typically 6 to 8 ms, 11 ms max.ST3 - Low sensitivity. Provides the least protection but may provide longer battery life and run time for tolerant equipment. The transfer time is typically 8 to 10 ms, 13 ms max.
13(Only available on TAA models)	Resets the UPS Power On Counter to 0. This counts the number of times the UPS has been powered on since the first startup or the last time it was reset.YES - Reset the counter to 0NO - Do not reset to 0 and return to setting selection
14(Only available on TAA models)	Resets all UPS Settings to their factory defaults.YES - Reset to factory default settingsNO - Do not reset to factory defaults and return to setting selection
00 Exit Settings mode.

4 Maintenance and Battery Replacement

4.1 Precautions

Although the Liebert ^® PSI5 is designed and manufactured to ensure personal safety, improper use can result in electrical shock or fire. To ensure safety, observe the following precautions:

• Turn off and unplug the UPS before cleaning it.
• Clean the UPS with a dry cloth. Do not use liquid or aerosol cleaners.
• Never block or insert any objects into the ventilation holes or other openings of the UPS.
• Do not place the UPS power cord where it might be damaged.

4.2 Battery Charging

The batteries are valve-regulated, non-spillable, lead-acid in all models except for the LI, which uses LiFePO4 type lithium-ion batteries. In all cases, the batteries should be kept charged to retain their design life. The PSI5 charges the batteries continuously when it is connected to input power. If the PSI5 will be stored for a long time, Vertiv™ recommends connecting the UPS to input power every 4 to 6 months for at least 2 hours for LI models and 24 hours for lead acid models to ensure full recharge of the batteries.

The Lithium Ion batteries used in the PSI5 LI series, as well as all Vertiv Lithium-Ion UPSs, contain a Battery Management System (BMS) that self-monitors the safety of the LI batteries in real-time. This is an agency tested and certified requirement now eliminating the industry wide safety risk known with previous Li-Ion batteries.

4.3 Replacing the UPS Batteries

IMPORTANT! Before you proceed, please review the battery safety precautions available at https://www.vertiv.com/ComplianceRegulatoryInfo

You may safely replace the internal battery pack. See the Specifications on page 31, for the part number of the replacement battery for your UPS model number.

NOTE: Replace the battery with the same type and number as originally installed.

NOTE: The internal battery pack is hot-swappable. However, caution should be exercised because during this procedure the load is unprotected from disturbances and power outages. Do not replace the battery while the UPS is operating in Battery Mode. This will result in a loss of output power and will drop the connected load.

To replace the batteries on 1U and 2U models:

1. Remove the front bezel by pulling firmly until the snaps release.
2. Disconnect the battery connector by squeezing the ends and gently pulling the two pieces apart.
3. Remove the two screws and the metal battery cover plate.

4. Slide out the existing battery kit.

5. For LI models: Attach the provided connector to the replacement battery terminals. Plug the black wire in first then the red. For VRLA models: skip this step.

6. Orient the connector and the new battery in the same way as the original battery and slide into UPS.
7. Reconnect the two halves of the battery connector and slide the front panel back on until it clicks.
8. Replace the metal plate and secure with the two screws.
9. Snap the front bezel back on.
10. Press and hold the power button for 3 seconds to initiate the Battery-Self Check mode clearing any previous battery fault warning.
11. Properly dispose of the old batteries at an appropriate recycling facility or return them to Vertiv™ in the packing material from the new batteries.

5.1 Run Times

NOTE: Liebert® PSI5-1100/2200/3000/5000: When using 2 or more external battery cabinets (EBCs), the UPS load rating will be decreased by 20% . The % load graph on the LCD automatically adjusts to reflect this derating.

NOTE: Run times are approximate. They are based on new, fully charged batteries at a temperature of 25^ C ( 77^ F) with 100% resistive UPS loading.
