4.0 Applying Power to the Power Supply Panel
Now that all the Wiring is complete and the switch settings have been made, it’s time to apply power to the Power Supply
panel.
ALWAYS APPLY AC POWER BEFORE APPLYING BATTERY POWER. ALWAYS
REMOVE BATTERY POWER BEFORE REMOVING AC POWER. FAILURE TO DO SO
CAN CAUSE DAMAGE TO THE POWER SUPPLY COMPONENTS.
1. Connect AC source. The AC source shall be connected to a dedicated, non-switch power source. The AC must
first be wired into the buildings main electrical power. The conduit entry can be either from the top or left side
using the knock-outs. See Figure 8. Connect Earth Ground First.

2. Connect backup batteries. Batteries shall be Sealed Lead Acid type. Observe correct polarity and voltage. Use
two of the same size batteries connected in series as shown in Figure 9. Use up to 33 Ahr batteries depending
on circuit loading, BATTERY CALCULATION SHEET is provided on pages 20 and 21.
NOTE: The POWERPATH enclosure can accommodate two 12VDC batteries up to 7 Ahr in size. Batteries larger than
7 Ahr must be stored in a separate battery enclosure such as the Wheelock BATC Battery Enclosure.
