Reduce the number of NAC Appliances on Output1
Check for a wiring short. Check for improperly wired NAC
circuit. (If an appliance is wired + to – and – to + a short trouble
will be indicated.
Check SYNC BUS terminals for good connections. Check NAC
circuit wiring for continuity. Check NAC circuit for 10K Ohm
EOLR.
Excessive current on the SYNC BUS. Reduce the number of
Power Supplies connected to the circuit.
Check for circuit wire to enclosure or conduit.
