the battery installation. Risk of electrical shock.
: Batteries can present a risk of electrical shock or burn from high short circuit
current. The 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.
: ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or
connectors. Attempting to alter wiring can cause injury.
NOTE DO NOT DISCONNECT the batteries while the UPS is in Battery mode.
There are two ways to replace the batteries:
:
With utility power (hot-swapping). With the UPS in Maintenance Bypass
mode, utility power continues to support the connected equipment;
however, the equipment is not protected from utility failures.
:
Without utility power. The UPS shuts down completely, removing power
from the connected equipment.
