Troubleshooting
Device not receiving power
Check that the comb rail is securely connected to the power source. Verify that all connections between the comb rail and the device are tight and correctly seated. Ensure the device itself is functional.
Overheating at connection points
Turn off power immediately. Inspect connections for loose wires or corrosion. Ensure the wire gauge is appropriate for the current rating. Re-tighten connections or replace damaged components.
Comb rail does not fit enclosure
Confirm that the enclosure is designed for this specific comb rail (KB series) and that the module width (12 modules) is accommodated. Ensure no obstructions are present in the mounting area.
Inconsistent power across phases
Verify the incoming 3-phase power supply is balanced. Inspect all connections on the comb rail and to each device for equal tightness and integrity. Test voltage at each device terminal.
