2.2.6 Control circuit terminals (common to all models)
[ 1 ] Screw specifications and recommended wire size (control circuit terminals)
The specifications for the screws used in the control circuit wiring and the wire sizes are shown below.
The control circuit terminal block is common, regardless of the inverter capacity.
The control terminal block for the conventional model MEGA (GS1) is available as an option to allow round crimp
terminals to be connected.
Refer to Chapter 11 “11.21 Control Terminal Block (G1S Compatible) OPC-G1-TB1” for details.
