Important Note for Maintaining Power Supply
To make sure GV-AS / EV Controllers can function properly during a power outage, be sure
to replace the internal battery on the controllers when needed. It is also recommended to
install a backup battery for compatible GV-AS Controllers.
Refer to the following sections in GV-AS Controller User Manual for instructions on how to
install a backup battery:
z GV-AS100 / 110 / 120 through GV-ASBox: See 9.1.4.F Connecting Backup Battery.
z GV-AS100 / 110 / 120 through GV-ASNet: See 9.2.4.F Connecting Backup Battery.
z GV-AS210 / 2110 / 2120: See 4.2.4 Connecting Backup Battery
z GV-AS410 / 4110 / 810 / 8110: See 5.2.4 Connecting Backup Battery

For GV-AS100 / 2110 / 2120 / 4110 / 8110, you can replace the battery on your own when
you see low battery messages and icons in GV-ASManager.
Note: Make sure the plastic insulation film under the battery is removed when using GV-
AS100 / 2110 / 2120 / 4110 / 8110 for the first time. The low battery messages and icons will
appear if the plastic film is not removed.
