AccuLoad IV Clock Battery Replacement Instructions

WARNING:

do not perform this procedure in a hazardous area.

Recommended backup battery replacement interval - 5 years

13.6.1

Battery replacement procedure:

1. Remove power from the unit.

2. Remove connectors and ethernet cables from A4M and A4I boards as applicable.

3. Remove A4M from housing via the (4) captive fasteners on the corners of the A4M.

4. Locate the hole in the A4M mounting tray that allows access to the RTC battery.

5. Battery removal:

a. Position the A4M so the gold tab on the RTC battery socket is pointing

toward the technician.
