Environment-resistive Slave Units Section 5-2
5-2 Environment-resistive Slave Units
The Environment-resistive Slave Units are designed to be easily connected
with M12 connectors that lock by turning them 1/8 of a turn for less wiring.
5-2-1 Mounting in Control Panels
Use screws to mount a Waterproof Terminal in a control panel. These Termi-
nals cannot be mounted on a DIN Track.
Drill the mounting holes in the control panel according to the dimensions
shown in the dimensions diagrams and secure the Terminal with M5 screws.
The appropriate tightening torque is 1.47 to 1.96 N⋅m.
Installation Direction The Terminal can be mounted in any direction. Any one of the following 6
directions is acceptable.
