The UPS is designed for industrial or computer room applications, and contains safety shields
behind the door and front panels. However, the UPS is a sophisticated power system and should
be handled with appropriate care.
This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the

l
controlled, indoor environment, free of conductive contaminants. 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
l
is required for safety and proper product operation. Do not check UPS operation by any action
that includes removal of the earth (ground) connection with loads attached.
Emergency Power Off (EPO) and Remote Emergency Power Off (REPO) functionality is disabled
l
for UPS systems configured for UL 924 auxiliary lighting. To remove power from the system a
LOAD OFF command (see paragraph 6.3.15 or 6.4.17) must be given using the front panel
controls and all breakers opened.
Ensure all power is disconnected before performing installation or service.
l
Batteries can present a risk of electrical shock or burn from high short-circuit current. The
l
following precautions should be observed: 1) Remove watches, rings, or other metal objects;
2) Use tools with insulated handles; 3) Do not lay tools or metal parts on top of batteries;
4) Wear rubber gloves and boots.
