3.1.2. Replacing the Line Isolation Relay
Tools Required:
• #2 Phillips screwdriver
• Flathead Screwdriver
3. When lowering the new relay circuit board onto
the tabs, verify all tabs align with the sockets on
the relay circuit board. Failure to do so will result in
damage to the tabs or the sockets.
4. Verify the relay circuit board is pushed firmly into
place before replacing the front panel of the power
supply.
1. Verify the power supply is powered off and remove
AC and DC power sources from XM2. Remove
the leftmost front panel using a #2 Phillips head
screwdriver (screws circled at right).
2. Carefully loosen the relay circuit board with the
flathead screwdriver and lift from the fixture.
Before proceeding, remove all power from the power supply by unplugging the
power supply from the AC power source, removing all front panel connections (i.e.,
N+1) and disconnecting the battery connector. Failure to do so could expose the
technician to potentially lethal voltages.
