The maximum number of output relays that should be configured to be permanently
energized is 50% of those available (minimum 4).
1.7 Field Voltage
The field voltage provided by the relay is nominally 48V dc with a current limit of 112mA. The
operating range shall be 40V to 60V with an alarm raised at <35V.
1.8 Loop through connections
Terminals D17-D18 and F17-F18 are internally connected together for convenience when
wiring, Maxima 5A and 300V.
1.9 Wiring requirements
The requirements for the wiring of the relay and cable specifications are detailed in the
installation section of the Operation Guide (Chapter P44x/EN IN).
