2. Installation Description
2.1 Installation method
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.
2.2 Cable connection and specification
It is recommended to use stranded copper cables and prefabricate
insulated plugs to ensure connection quality. The following table lists the
sectional areas and models of the recommended cables.

correctly. Fastening torque: 0.5~0.8Nm.
Expansion port
◆For the safety (to prevent electric shock and fire accidents) and lower
noise, the ground terminal of the controller should be connected in
accordance with the requirements from national electrical regulations, and
the ground resistance should be less than 100 Ω . Single point grounding
should be used when wiring multiple controllers, and the ground wire cannot
form a loop. As shown in the diagram below:
Note for wiring:
1. It is recommended to use a shielded twisted-pair cable for analog input.
The cable should be far away from power cable or other cables that may
generate electrical power interference.
2. Grounding terminal PG of the module is well grounded.
3. Do not use the empty pin on the terminal.
