Remote Cable Connection
Electical power must be disconnected from explosion proof models before
the cover is removed. Failure to do so could result in severe personal injury
or substantial property damage.
Ensure that wiring conforms to all applicable local and national electrical codes and install
unit(s) according to relevant national and local safety codes.
Fishing the Sensor Extension Cables
One three-conductor extension cable is required. Pull cable from the sensor base so that
the free ends follow the fish through the conduit. (See
).
Connections Inside Sensor Base
Inside the sensor base, a remote circuit
board rests in a plastic holder. Attach the
cable wires to the terminal block on the
circuit board as follows:
Connections Inside Electronics Housing
Inside the electronics housing, unscrew the bracket holding the circuit board in place. Pull
the board out of the holder. At the bottom of the circuit board, there is a connector labeled
“+ - probe”. Attach the cable wires to the terminal block as shown above.
Conduit must be installed between the sensor base and the electronics housing to provide a
raceway for sensor extension cables. (See
).
