3.3 Installation Method
The PLC must be installed horizontally on the backplane of the
electrical cabinet, and maintain a distance of more than 20cm from the
peripheral equipment or cabinet wall. The installation in other directions is
not conducive to the PLC heat dissipation, and there can be no heating
equipment under the PLC. As shown in the picture below:
Ceiling installation
Horizontal installation
DIN rail mounting
Generally, you can mount the PLC onto a 35mm-wide rail (DIN). Open
the DIN snap-fit at the bottom of the module and lock the bottom of the
module onto the DIN rail; Rotate module close to the DIN guide rail and close
the DIN snap-fit with a double-checking.
Screw fixing
Fixing the PLC with screws can stand greater shock than DIN rail
mounting. M3 screws can be chosen to fix the PLC onto the backboard of the
electric cabinet through the mounting holes on PLC enclosure, as the
following figure.
