4.13 Connecting Internal Battery Strings
This battery section contains its own energy source. Risk of electric shock. Do not touch
uninsulated battery terminals. The internal wiring may carry LETHAL VOLTAGES.
Internal battery strings should be connected by a qualified electrical contractor knowledgeable of
battery systems, and required precautions.
Connect battery strings only after all wiring is complete.
The UPS is shipped with each battery tray string electrically disconnected. To connect the battery tray strings:
1. If not already open, open the front door (see Figure 4-1) by lifting the latch from the bottom and turning to
the right (counterclockwise) and swing the door open.
2. Remove the screws securing the bottom internal safety shield panel (see Figure 4-22) and remove the
panel to gain access to the battery section (see Figure 4-23). Retain the hardware for later use.
3. Connect the red and black connectors marked with the white flags (see Figure 4-24) for each set of
batteries on the battery shelf.
4. Connect the black connectors (see Figure 4-24) for each set of batteries on the battery shelf.
5. Connect the red connectors (see Figure 4-24) for each set of batteries on the battery shelf.
