Safety Precautions

Electrical connection must be carried out by specialized personnel only. Read safety manual instructions before connecting to power.
Do not make electrical connections with device connected to power.
Do not run other cables through the designated power cable gland.
Have a disconnect switch installed in the vicinity of the instrument to ensure electrical circuit is de-energized for installation.

Connecting to Power

Loosen the four screws, enough for the springs to push them out.
Grasp the front bezel and swing open to access the two-terminal power supply board.
Remove the safety cover to access Terminal 1 block (power path).
Remove the blank plug and thread the cable through the power cable gland.
Connect the power cable leads to the removable terminal connector marked POWER.
Follow L (live), PE (ground), N (neutral) lead markings for correct wiring of output leads.
Carefully put wired terminal connector into place on the board.
Replace safety cover over Terminal 1.

Terminal 1 (Power path)

Terminal 2

Controller Wiring

High voltage connections: POWER, ALARM, REL 1 to REL 5 (relays) are made to the Terminal 1 block.
Low voltage connections: COMM (RS-485), PROBE1, IN1 and IN2 (digital inputs), A01 to A04 (analog outputs), and PROBE2 are made to the raised Terminal 2 block.
Follow the positive/negative lead markings to ensure that output leads are wired to the correct position on the main board.

Probe Wiring

Ensure the controller is not powered.
Run the probe cable through the conduit opening.
Connect probe leads to the removable terminal connector marked PROBE1 or PROBE2.
Follow the lead markings (positive/negative) for correct wiring.
Carefully put the wired terminal connector into place on the board.
Position excess cable through the cable gland before tightening the nut.
Remove the ground screw and hardware located below the PROBE1 or PROBE2 connector. Attach the ground lead ().
