Connecting the Power Cord
Follow these instructions when supplying power to the unit:
When the frame ground (FG) terminal is connected, verify the wire is grounded. Not
grounding the unit can result in excessive Electromagnetic Interference (EMI).
Grounding is required to meet EMC level immunity.
The shield ground (SG) and FG terminals are connected internally in the unit.
Remove power before wiring to the power terminals of the unit.
The unit uses 24 Vdc power. Using any other level of power can damage both the
power supply and the unit.
Since the unit is not equipped with a power switch, connect a power switch to the unit’s
power supply.
Field wiring terminal marking for wire type (75
° C (167F) copper conductors only).
