Chapter 5—System Configuration and Operation
Stand Alone Ground Fault Module
Description
The C445 system may be configured as a standalone system
whereas only ground fault monitoring and indication is
enabled. In such a configuration, a C445B... base module is
coupled to an External Ground Fault Module connected to
the appropriate sized CT to transmit monitoring information
via a network. A C445M... measurement module and/or a
C445UM user interface module may be added to provide
local indication, control, and protection.
C445 outputs:
Output 1 and 2 are general purpose outputs
●
Output 3 is default as the ground current trip relay
●
When the C445 Motor Management relay is powered on
for the first time with the External Ground Fault Module,
output 3 will default as the ground trip relay.
If a different output relay is desired for this operation,
outputs 1, 2 and 3 – open for user configuration and their
function can be selected by the user.
