Applicable Industries

Installation Requirements

1. Install module into standard Genius remote I/O rack vertical slot, fully lock front module latch
2. Field 120V AC input wiring use separate cable raceway isolated from low-voltage DC control wiring
3. Genius bus communication cable must be shielded twisted pair with single-end cabinet earth grounding
4. Rack power supply rated capacity match total combined power consumption of all installed I/O modules
5. Maintain 10mm minimum vertical spacing between stacked I/O modules for heat dissipation

Operation & Maintenance Precautions

1. Do not apply voltage exceeding 132V AC to any discrete input channel terminal
2. Inspect terminal block screw torque every 6 months to eliminate loose contact heating
3. Bus communication fault LED constant red indicates cable short or termination resistor missing
4. Only GE factory specified Genius bus termination resistors installed at bus segment endpoints
5. Module disassembly voids factory calibration and isolation performance warranty
