Description
The Sensorform EFI-CFZ consists of the following components:
2.1
Control Unit
This contains the necessary monitoring and detection circuits for detecting and
validating an earth fault as well as activating the fault indicator.
The control unit is normally mounted onto a vertical surface. When the cover is
removed, mounting screw holes are exposed for use in fixing the indicating unit
to a surface. Four two-way screw terminals inside the unit provide a means of
connecting the Power CT, Remote Reset, Aux. Relay and CT Sensor to the
unit. These cables are fed through the cable glands (M12) provided and
secured in place using the locking nut. When the cover and cable glands are
tightened firmly the enclosure provides IP65 protection.
