Electrical
The CoreSense is an overvoltage category II instrument.
Use only fuse(s) specified as appropriate for this equipment (see “Technical specifications” on
page A51.)
In accordance with international safety standards, the sensor uses a three-wire power cord typically
connected to an electrical panel that provides grounding for the sensor chassis.
DANGER
Disconnect power at the distribution panel circuit breaker before opening the sensor.
Ensure that the equipment and all devices or power cords connected to the sensor are
properly grounded. Make sure that the sensor ground is at the same potential as the
transformer ground.
Protective earthing connection (grounding) must be active at all times.
The absence of grounding can lead to a potential shock hazard that could result in
serious personnel injury. If an interruption of the protective earthing is suspected, cut
the power to the sensor at the plant’s distribution panel and have the electrical circuit
tested.
