WARNING
To reduce the risk of fire or electric shock, install the UPS in a
temperature and humidity controlled, indoor environment that is free of
conductive contaminants. The ambient temperature must not exceed
40 °C (104 °F). Do not operate near water or excessive humidity (95%
maximum). The system is not intended for outdoor use.
As a result of the connected loads, high leakage current is possible.
Connection to earth ground is required for safety and proper product
operation. Do not check UPS operation by any action that includes
removal of the earth (ground) connection.
Before you start any installation or service work, make sure that all AC
and DC power sources are disconnected. Power may come from
multiple sources.
When undertaking installation or service work, ensure system
grounding continuity.
In a parallel system, the output terminals may be energized even when
the UPS is turned off.
Batteries can present a risk of electrical shock or burn from high short
circuit current. Always observe the following precautions when
working with batteries:
1) Remove watches, rings, or other metal objects.
2) Use tools with proper insulation.
3) Do not lay tools or metal parts on top of batteries.
4) Wear rubber gloves and boots.
Electric energy hazard. Do not attempt to alter any battery cabling or
connectors. Attempting to alter cabling can cause injury.
Do not open or mutilate batteries. Released electrolyte may be toxic
and is harmful to the skin and eyes.
The UPS may be connected to TN and TT power distribution systems.
The UPS unit is not suitable for IT (Isolated neutral or impedance-
earthed neutral) or corner-earthed power distribution systems.
IMPORTANT: The battery may consist of multiple parallel strings.
Make sure that you disconnect all strings before installation.
