3. Installation instructions

3.1 Attention items of installation

●The UPS installation environment must be with good ventilation, away from water, flammable gases and corrosive entities.

●Do not lie down the UPS against the wall so that front and side panel air intake hole, rear panel air outtake hole will be unobstructed.

●The peripheral environment temperature around the UPS should be within 0 ℃ ~ 40 ℃.

● If dismantling the machine at low temperatures, there may be condensation droplets, users can not install or operate it before UPS completely got dry both inside and outside, otherwise there will be danger of electric shocks.

● Place the UPS near the mains socket so that can cut off AC mains without any delay at any emergent case.

●Make sure the load connect to the UPS is off when users connect the load to UPS, and then turn on the load one by one later.

●Please connect the UPS with the socket which is over-current protected. Do not connect the UPS with the socket which rated current is less than the Maximum input current of the UPS.

●All the power socket should be configured with earthing device for safety.

●UPS could be electrified or powered no matter the input power cable is tied or not, even when the UPS is off.

The only way to cut off the output is switching off the UPS and disconnecting the mains power supply.

●For all standard type UPS, it is advised to charge the battery over 8 hours before used. Once the AC mains power energizes the UPS, it will automatically charge the battery. Without prior charging, UPS output remains as usual but with shorter back-up time than normal.

●When connected to motor, display equipment, laser printer etc, UPS power selection should be based on the startup power of the load which is usually twice as rated power.

●When wiring, please ensure input cables and output cables are connected firmly.

●If install a leakage current protective switch, please install it on output cable.

●For EA900II 6-20K Series UPS, before installing, prepare wires for terminal block of the UPS based on the following tables.
