Disconnect Input
This feature allows an external dry-contact switch to notify the G5 Stack Switchgear to disconnect
the battery from the DC bus. The signal can be daisy-chained to adjacent G5 Stack Switchgear
units that also share the same DC bus.
The Disconnect input requires the signal to be asserted for a minimum of 500ms when the G5
Stack Switchgear is configured for normal disconnect mode. When configured for fast disconnect
mode, the G5 Stack Switchgear instantly reacts to the input.
In the unlikely event the G5 Stack Switchgear is unresponsive, asserting the Disconnect Input for
10 seconds will override the software to disconnect the battery from the DC Bus using a hardware-
only circuit.
