Equipment Description

This automatic transfer switch is used for transferring electrical load from a utility (normal) power source to a generator (standby) power source. Transfer of electrical loads occurs automatically when the utility power source has failed or is substantially reduced and the generator source voltage and frequency have reached an acceptable level. The transfer switch prevents electrical feedback between two different power sources (such as the utility and generator sources) and, for that reason, codes require it in all standby electric system installations.

The transfer switch consists of a transfer mechanism, utility service disconnect circuit breaker (if equipped), and a Smart A/C module incorporating fuses and two terminal blocks for transfer switch connections.

This transfer switch is equipped with a separately accessible Utility Entry cabinet which houses a standard 4 Jaw Meter Socket. It is provided with a means for the Electrical Utility provider to lock. An optional 5th Jaw Kit is available if required.

The lower cabinet contains the Automatic Transfer Switch and Service Disconnect Main Circuit Breaker with Load Shed Module and customer terminations. RBU Models do not come equipped with a transfer switch. They may be upgraded to include a transfer switch with G0074000 Upgrade Kit.

NOTE: Meters are retained by either a Ring or Ringless method. Verify you have the proper type to meet local code requirements.

Transfer Switch Mechanism (RXUW Models or RBU with Upgrade Kit (G007400) Installed)

See Figure 2-1. This switch is used with a single-phase system when the single-phase neutral line is to be connected to a neutral lug and is not to be switched.

Solderless, screw-type terminal lugs are standard.

The conductor size range of the 4 Jaw Meter Socket is as follows:

Switch Rating	Wire Range	Conductor Tightening Torque
150/200A	#6-250 MCM (Cu/Al)	275 in-lbs (31 Nm)

This transfer switch is suitable for control of motors, electric discharge lamps, tungsten filament and electric heating equipment where the sum of motor full load ampere ratings and the ampere ratings of other loads do not exceed the ampere rating of the switch and the tungsten load does not exceed 30 percent of the switch rating.

This ETL listed transfer switch is for use in optional standby systems only (NEC article 702).

A 150A or 200A rated switch is suitable for use on a circuit capable of 22,000 RMS symmetrical amperes, 240 VAC when protected by a circuit breaker without an adjustable short time response or by fuses.

When requesting information or ordering parts for this equipment, make sure to include all information from the data decal.

For future reference, record the Model and Serial numbers in the space provided on the front cover of this manual.

Transfer Switch Enclosure

The standard switch enclosure is a National Electrical Manufacturer's Association (NEMA) and 3R type. ETL and NEMA 3R (indoor/outdoor rated) type enclosures primarily provide a degree of protection against falling rain and sleet; are undamaged by the formation of ice on the enclosure.

Safe Use of Transfer Switch

WARNING

Consult Manual. Read and understand manual completely before using product. Failure to completely understand manual and product could result in death or serious injury. (000100a)

Before installing, operating or servicing this equipment, read the Safety Rules carefully. Comply strictly with all Safety Rules to prevent accidents and/or damage to the equipment. The manufacturer recommends that a copy of the Safety Rules be posted near the transfer switch.

Also, be sure to read all instructions and information found on tags, labels and decals affixed to the equipment.

Publications that outline the safe use of transfer switches are the following:

• NFPA 70; National Electrical Code
- UL 1008: Standard for Safety—Automatic Transfer Switches
- UL 891 (Busbar)
• ANSI C12.7 Meter Sockets

NOTE: It is essential to use the latest version of any standard to guarantee correct and current information.

Load Management Options

Load management systems are designed to work together to prevent a generator from being overloaded by large appliance loads. A Smart A/C Module (SACM) is provided as standard equipment with this switch. An optional Smart Management Module (SMM) is also available.

Smart A/C Module (SACM)

Up to four air conditioner loads can be managed by the SACM. The SACM manages the loads by "shedding" the connected loads in the event of a drop in generator frequency (overload). Loads to be "shed" are in four priority levels on the module.

See Figure 2-2. Priorities A/C 1-4 (A) have connections for an air conditioner. To control an air conditioner, no additional equipment is required. Internal normally closed relays interrupt the 24 VAC thermostat control signal to disable the air conditioner load.

Four LEDs, located on the SACM (B), illuminate when a load is connected and powered.

See Figure 2-2. The SACM has a test button (C) used to simulate an overload condition. This button operates even when the transfer signal is inactive. The Generator Control Wiring is connected to terminals (D).

Figure 2-2. Smart A/C Module (SACM)

Application Considerations

Generator overload condition is determined by generator frequency. Loads are shed when frequency is less than 58 Hz for three seconds or less than 50 Hz for 12 second (for 60 Hz systems).

The SACM can be used in conjunction with individual SMMs to manage a combined total of eight loads.

• Use Priorities A/C 1-4 on the SACM as the top priorities, then up to four SMMs as Priorities 5-8.
• Use only select A/C priorities on the SACM as the top priorities, then use additional SMMs as the remaining priorities.
• A SMM can share a priority with an A/C priority on the SACM provided the generator is sized to handle the combined surge load from both appliances. Sharing priorities can allow up to 12 loads to be managed in a properly sized system.

In any combination of modules, the recovery times after a loss of utility power or shutdown due to overload are shown in Table 1.

Table 1. Priority Settings

Priority	Recovery Time	SACM	SSMM
1	5 minutes	Yes	Yes
2	5 minutes 15 seconds	Yes	Yes
3	5 minutes 30 seconds	Yes	Yes
4	5 minutes 45 seconds	Yes	Yes

Voltage Checks

NOTE: Use the Digital Multimeter (DMM) LowZ low input impedance setting to collect accurate voltage measurements. LowZ eliminates the possibility of inaccurate ghost voltage readings, also known as phantom voltage or stray voltage readings. See DMM manufacturer's literature for additional information.

Utility Voltage Checks

DANGER

Electrocution. High voltage is present at transfer switch and terminals. Contact with live terminals will result in death or serious injury.

(000129)

1. Turn ON the utility power supply to the transfer switch using the utility service disconnect circuit breaker.
2. With an accurate AC voltmeter, check for correct voltage. Measure across ATS terminal lugs N1 and N2; N1 to NEUTRAL and N2 to NEUTRAL.

Generator Voltage Checks

DANGER

Electrocution. High voltage is present at transfer switch and terminals. Contact with live terminals will result in death or serious injury.

(000129)

1. On the generator panel, select MANUAL. The generator should crank and start.
2. Let the generator stabilize and warm up at no-load for at least five minutes.
3. Set the generator's main circuit breaker (CB1) to ON or CLOSED.
4. With an accurate AC voltmeter and frequency meter, check the no-load, voltage and frequency. Measure across ATS terminal lugs E1 to E2; E1 to NEUTRAL and E2 to NEUTRAL.

Frequency	60–62 Hz
Terminals E1 to E2	240–246 VAC
Terminals E1 to NEUTRAL	120–123 VAC
Terminals E2 to NEUTRAL	120–123 VAC

1. When certain the generator supply voltage is correct and compatible with transfer switch ratings, turn OFF the generator supply to the transfer switch.
2. Set the generator main circuit breaker (CB1) to OFF or OPEN.
3. On the generator panel, select OFF to shut down the generator.

NOTE: Do NOT proceed until generator AC output voltage and frequency are correct and within stated limits. If the no-load voltage is correct but no-load frequency is incorrect, the engine governed speed may require adjustment. If no-load frequency is correct but voltage is not, the voltage regulator may require adjustment.

Generator Tests Under Load

1. Set the generator main circuit breaker to OFF or OPEN.
2. Set the utility service disconnect circuit breaker of the transfer switch to OFF or OPEN, and turn OFF or OPEN all load circuit breakers.
3. Manually actuate the transfer switch main contacts to the emergency (standby) position. See Manual Operation.

4. To start the generator, select MANUAL. When engine starts, let it stabilize for a few minutes, and close lid (if applicable).

5. Set the generator main circuit breaker to ON or CLOSED. The generator now powers all LOAD circuits. Check generator operation under load as follows:

6. Turn on electrical loads to the full rated wattage/amperage capacity of the generator. DO NOT OVERLOAD.

7. With maximum rated load applied, check voltage and frequency across transfer switch terminals E1 and E2. Voltage should be greater than 230 VAC (240 VAC system); frequency should be greater than 59 Hz.
8. Verify the gas pressure remains within acceptable parameters (see the generator Installation manual).

9. Let the generator run under rated load for at least 30 minutes. With unit running, watch for unusual noises, vibration, or overheating that might indicate a problem.

10. When checkout under load is complete, set main circuit breaker of the generator to OFF or OPEN.

11. Let the generator run at no-load for several minutes. Then, shut down by selecting OFF.

12. Move the main switch contacts back to the utility position.
