2. Installation Description
2.1 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:
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
prefabricate insulated plugs to ensure connection quality. The following
table lists the sectional areas and models of the recommended cables.

Fix the prepared cable head onto the PLC terminals with screws
correctly. Fastening torque: 0.5~0.8Nm.
◆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. If there is interference in the external electrical wiring and the input
signal fluctuates, you can connect a smoothing capacitor (0.1μF ~ 0.47 μF
/25V).
