4.1 Transportation

- Transport the UPS system only in the original package to protect against shock and impact

4.2 Preparation

• Condensation may occur if the UPS system is moved directly from a cold to warm environment. The UPS system must be absolutely dry before being installed. Please allow at least two hours for the UPS system to acclimate the environment.
• Do not install the UPS system near water or in moist environments.
• Do not install the UPS system where it would be exposed to direct sunlight or near a heater
• Do Not block ventilation holes in the UPS housing.

4.3 Installation

• Do not connect appliances or devices which can overload the UPS system (e.g. laser printers) to the UPS output sockets
• Place cables in such a way that no one can step on or trip over them.
• Do not connect appliances such as hair dryers to UPS output sockets.
• Connect the UPS system only to an earthed shock proof outlet.
• Please use only the included VDE-tested, CE-marked mains cable (e.g. the mains cable of your computer) to connect the UPS system to the building wiring outlet (shockproof outlet).
• Please use only VDE-tested, CE-marked power cables to connect the loads to the UPS system.
• When installing the equipment, ensure that the sum of the leakage current of the UPS and the connected devices does not exceed 3.5mA
• Temperature Rating - Units are considered acceptable for use in a maximum ambient temperature of 40^ (104°F)
• FOR PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment and shall be easily accessible.
• CAUTION: The unit is heavy. Lifting the unit requires at least two people
• Check if there is a protection devices against over current and short circuit in the upstream of the UPS system. The recommended protection specification is 11A for 800VA\~1100VA, 15A for 1.5 VA, 20A for LV 2KVA and 30A for 2.5\~3KVA with a B or C trip curve.

4.4 Operation

• Do not disconnect the mains cable on the UPS system or the building wiring outlet (shockproof socket outlet) during operations since this would cancel the protective earthing of the UPS system and of all connected loads.
• The UPS system features its own, internal current source (batteries). The UPS output sockets or output terminals block may be electrically live even if the UPS system is not connected to the building wiring outlet.
• In order to fully disconnect the UPS system, first press the OFF/Enter button to disconnect the mains.
• Prevent fluids and other foreign objects from entering the UPS system.
• The EPO, RS-232 and USB circuits are IEC 60950-1 safety extra low voltage circuits by reinforced insulation

4.5 Maintenance, Service and Faults

• The UPS system operates with hazardous voltages. Repairs should be carried out only by a qualified technician
- CAUTION - risk of electric shock. Even after the unit is disconnected from the mains (building wiring outlet), components inside the UPS system are still connected to the battery and electrically live and dangerous.
- Before carrying out any kind of services and/or maintenance, disconnect the batteries and verify that no current is present and no hazardous voltage exists in the terminals of high capability capacitor such as BUS-capacitors.
• To avoid electrical shock, turn off the unit and unplug it from the AC power source before servicing the battery
- Only persons who are adequately familiar with batteries and with the required precautionary measures may replace batteries and supervise operations. Unauthorized persons must be kept well away from the batteries.
- CAUTION - risk of electric shock. The battery circuit is not isolated from the input voltage. Hazardous voltages may occur between the battery terminals and the ground. Before touching, please verify that no voltage is present.
- Batteries may cause electric shock and have a high short-circuit current. Please take the precautionary measures specified below and any other measures necessary when working with batteries:

- Remove wristwatches, rings and other metal objects

- Only tools with insulated grips and handles.

• When changing batteries, install the same number and same type of batteries.
• Do not attempt to dispose of batteries by burning them. This could cause battery explosion
• Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may be toxic
• When replacing batteries, use the same type and number of batteries or battery packs
• A battery can be at risk for electrical shock and high - short circuit current.
  • The following precautions should be observed when working on batteries:

a. Remove watches, rings, or other metal objects.
b. Use tools with insulated handles.
c. Wear rubber gloves and boots.
d. Do not lay tools or metal parts on top of batteries.
e. Disconnect charging source prior to connecting or disconnecting battery terminals.
f. Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock can be reduced if such grounds are removed during installation and maintenance
