IF BATTERY SYSTEM IS GROUNDED: (system is intentionally grounded by connecting a
battery terminal to ground)
1. An increased shock hazard exists between the terminal of
opposite polarity and ground (i.e., dirt and acid on top of battery
cell touching rack).
2. If an unintentional ground develops within the already grounded
system, a short circuit may occur and cause explosion or fire.
IF BATTERY SYSTEM IS UNGROUNDED (system is NOT grounded):
1. If an unintentional ground develops within the system, an
increased shock hazard exists between the terminal of opposite
polarity and ground.
2. If a second unintentional ground develops within the already
unintentionally grounded system, a short circuit may occur and
cause explosion or fire.
Therefore, should you be required to work on a grounded battery system, make absolutely
sure you use the correct safety precautions, equipment and clothing.
IMPORTANT:
If you have ANY questions concerning safety when working with the battery
system, contact your nearest EnerSys

sales/service representative to clarify any of
the noted safety precautions, or call the corporate office number listed on the back
of this manual and ask for EnerSys Reserve Power Service.
