BENSHAW RSi GX Series - Control Circuit Terminals

Control Terminals
3.6 Control Circuit Terminals
z Note:
•
Tie the control wires no more than 15cm away from the control terminals. Otherwise, it
interferes with front cover reinstallation.
•
Use copper wires rated 600V, 75W and higher.
•
Use the recommended tightening torque when securing terminal screws.
•
When you use external power supply (24V) for multi-function input terminal (P1-P8),
terminals will be active above 12V level. Take caution not to drop the voltage below
12V.
