Field Installation Guidelines

• Mount the compact terminal unit firmly onto panel structures, maintaining vertical airflow spacing to support thermal convection across -40 to +70 deg C operating environments.
• Route Ethernet and RS485 communication lines separately from 24 VDC power and high-voltage AC conductors to reduce electromagnetic noise coupling.
• Verify that the incoming 24 VDC auxiliary power supply strictly complies with rated voltage tolerances and polarity conventions prior to energization.
• Secure all digital input and output screw terminal terminations to mechanical torque specifications to prevent intermittent connection faults under vibration.
