Caution!
• Switch off power supply before opening the housing cover. Do not install or connect the unit to
power supply. If this is not followed parts of the electronic circuit will be damaged.
• If the device has not been grounded as a result of the housing being installed, we recommend
grounding it via one of the ground screws.
• Sensors:
Connect the sensor cables to the respective head transmitter terminals (Terminals 3 to 6) by
following the wiring diagram (see Fig. 6).
• Output signal and power supply:
Open the cable gland on the sensor head or field housing. Feed the cable through the opening in
the cable gland and then connect the cable cores to terminals 1 and 2 according to the wiring
diagram (see Fig. 6).
• PC configuration (SETUP socket):
Open the flap on the SETUP socket (see Fig. 6) and connect the SETUP connection cable.
