Terminal Information - Power (Frames 6 & 7)
These terminals are located externally on the product.
Auxiliary Supply
Live 115-230V Frame 6
Auxiliary Supply
Live 110-240V Frame 7
Auxiliary Supply
Neutral
These terminals are the mains input connections for control supply transformer and contactor relay supply L
N
Main contactor coil
V AC
This terminal is internally connected to the auxiliary supply neutral and provides a convenient connection point for
the contactor coil neutral connection
N
Main contactor coil
V AC
This terminal is the switched output from the contactor control relay and is derived from the auxiliary supply. The
output is internally fused at 3A hence contactor coils having a high pick-up current must be operated via a slave
relay.
Note: The contacts of the Contactor Control Relay are suppressed by a series connected resistor (680 Ohms) and
capacitor (22nF) to protect the relay contacts. Users should be aware that when the contactor Control Relay is
“De-energised”, a leakage current of approximately 2mA can be expected and this should be considered when
interfacing to these terminals. Typically, there could be the energisation of very sensitive relays.
