Replacement
Procedure
The replacement battery assembly includes a metal bracket and cable assembly.
To replace the NET-PATHm UPS battery
1
Remove the commercial power connection from the rear of the NET-PATHm.
2 Press the UPS Off button to perform a Safe Shutdown.
3
Disconnect the cables from the back of the NET-PATHm. Be sure to mark your
cables so you can reconnect them quickly.
4 Remove the screws that secure the NET-PATHm rear panel.
5 Remove the battery retaining screws on the bottom of the NET-PATHm.
6
Carefully slide the main board from the case.
7 Disconnect the battery power connector from the main board.
8 Remove the screw that secures the battery to the main board.
9
Lift the battery off the main board .
10 Insert the new battery assembly and secure it with the retaining screws. Be sure
the new battery has the same physical and electrical orientation as the old battery.
11 Attach the new battery power connector to the main board making sure the red
wire is on the left when viewed from the front of the NET-PATHm. Be careful.
The connector is keyed, but it is possible to force it in backwards. This will
change the polarity of the battery and will damage the NET-PATHm.
12
Reinstall the cover and replace the retaining screws.
13 Attach the cables to NET-PATHm.
14 Apply power to the unit.
15
The battery LED indicator should illuminate to indicate that the battery is fully
charged, or flash slowly to indicate that the battery is charging. If the battery
LED indicator is off, the new battery may be defective, or its polarity may be
incorrectly oriented. Check the connector to ensure it is plugged in correctly. Red
connects to the positive terminal and black to the negative terminal of the battery.
