1. Open the controller cover.
2. Feed the wires through the cable gland.
3. Adjust the wire as necessary and tighten the cable gland.
4. Make connections with twisted-pair shielded wire and connect the shield at the controlled
component end or at the control loop end.
• Do not connect the shield at both ends of the cable.
• Use of non-shielded cable may result in radio frequency emission or susceptibility levels higher
than allowed.
• Maximum loop resistance is 500 ohm.
5. Close the controller cover and tighten the cover screws.
6. Configure outputs in the controller.
