Installation & Wiring

1. Mount in a TDC3000 I/O rack and secure with screws.

2. Use shielded twisted-pair cables for analog signals; separate from high-voltage lines.

3. Connect digital inputs/outputs per Honeywell wiring diagrams.

4. Ensure proper grounding to reduce noise and avoid ground loops.

Maintenance & Safety

• De-energize the rack before installation/removal.

• Inspect wiring/terminals periodically; keep the module clean.

• Do not disassemble; use only original Honeywell replacements.

• Operate within rated temperature, voltage, and current limits.
