Installation Mounting the base unit
9 – 10
● Avoid mounting base unit in proximity to vibration sources such as large magnetic contactors
and no-fuse circuit breakers; mount these on a separate panel or at a distance.
● Install wiring ducts with sufficient dimensions.
If the wiring duct is mounted above the PLC, the depth of the wiring duct should be maximum
50 mm, so that the ventilation is not affected.
Keep enough distance to the controller that cables and modules can be easy replaced in
future.
If the wiring duct is mounted below the PLC, give enough space for the power supply input
cables (100/230 V AC) and for the cables to the I/O modules.
● In order to avoid the effects of radiated noise and heat inside the cabinet, provide a clearance
of minimum 100 mm between the PLC and devices that generate noise or heat (contactors
and relays). The device could be mounted on the internal side of the cabinet. The required
clearance of the device on the right and left side of the PLC is minimum 50 mm.
