settings. The current differential module in itself is highly programmable but the interaction in the
system has been kept to a minimum in order to simplify the system user interface.
NOTE
While most of the GARD 8000 Modules can be installed and removed while powered, it is not
recommended to do so while Tripping Circuits are enabled as unintended operations may
result.
