21.4.2 Battery Connections
Each PowerGen system is equipped with an internal 40 Ah battery for system control power
which will last up to 72 hours when the system is in ‘Standby’. Due to the nature of operation,
the system may be in standby in excess of a 72 hour period. For this purpose, both system
batteries are interconnected to ensure that the standby battery is maintained when the
primary system is running. The battery connections are made using an 8 AWG battery cable
which is protected by a 24A 42 VDC Circuit Breaker (Figure 21-9). The battery capacity setting
in the QEC configuration must reflect the interconnection of both batteries and is set to 80 Ah
for the two 40 Ah parallel batteries.

21.4.3 Operation
For the redundant interlock to operate, both PowerGen must be switched from ‘Local’ to
‘Remote’ to be remotely enabled (See “User Interface Indicators and Controls” on page 23).
When controlled by the customer or automatically from the ATS, the PowerGen may be
enabled and disabled remotely through the FEB input which is set to ‘System toggle’.
Normal connection is to FEB input 1 and should be a potential free ‘dry’ contact whereby a
closed contact will enable the PowerGen and a subsequent open contact will disable the
PowerGen. The customer may control the operation of the PowerGen based on usage or
through monitoring of the PowerGen status.
When controlled automatically by the Automatic Transfer Switch the primary PowerGen must
initially be started manually in ‘Local’ and then both systems switched to ‘Remote’ once the
primary PowerGen is outputting to the customer loads.
The primary PowerGen will continue to run and output power unless there is condition
whereby the outputs go off (fault or manual intervention). In this case the ATS will
automatically start the standby PowerGen through the connection between the ATS -X3 and
the PowerGen FEB input. The Standby PowerGen will then continue to run as the Primary unit.
CAUTION:
When connecting batteries, negative (-VE) should be
disconnected first and reconnected last.
