Installing the New Battery

take out the Battery.

minal, and place the new Battery in the round frame.

Replace the Waterproof Packing from the front of the panel to ensure water-
proofing performance (IP65 for NV3W/NV3Q and IP67 for NV3W-V1 or
NV4W) if the NV-series PT has been removed from the panel and you are
installing it again. Refer to 4-1-7 Waterproof Packings for information on
