Troubleshooting
No power to connected devices
Verify that the main power supply is active and correctly connected to the comb rail. Check all individual device connections to the comb rail for tightness and proper seating. Ensure the comb rail is correctly installed and is not bypassed.
Overheating at connection points
Immediately de-energize the system. Check that all connections are torqued to the manufacturer's specifications. Ensure the connected devices are properly seated on the comb rail and that the total current draw does not exceed the 80A rating. Inspect for any signs of corrosion or damage at the connection points.
Phase imbalance detected
Confirm that the comb rail is installed in a 3-phase system and that the connections are made correctly to each phase. Ensure that the loads connected to each phase are as balanced as possible. Check for loose connections that might be affecting one phase more than others.
Device does not fit comb rail
Verify that the device's module width (24 units) and division size (9mm) match the specifications of the comb rail. Ensure you are attempting to connect compatible devices that are designed for this type of comb rail system.
