5 Connections
The C6200 FlexGen is wired up through plug-in terminals. The plug-in terminals provide safe and
durable connections without sacrificing ease of installation and servicing. One exception is the
inputs for the currect transformers, which are fixed terminals to avoid shock from accidental
disconnection of live current inputs.
5.1 Power Supply
The circuitry of the the C6200 FlexGen must be powered by a single external power supply. The
supply must provide a nominal voltage of +24 V DC. The C6200 FlexGen will tolerate relatively
wide variations in the supply voltage (please refer to the specifications). The supply is connected to
terminal 30 and 32 of the AUX SUPPLY plug-in connector.

-24 V DC
Negative terminal of primary supply
The auxiliary power supply is not isolated from the remaining circuitry. This means that the supply
reference terminal (terminal 32) has connection to the module
’
s COM terminal.
The front AUX SUPPLY LED illuminates with a steady green light to indicate that the supply
voltage is OK and within the tolerated limits for safe operation.
