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.

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. Thermocouple signals are connected by shielding compensation
cables, which should be routed separate from power cables or other cables
that may be source of electrical interference. An appropriate compensation
cables( within 100m) is recommended to reduce the noise interference.
Compensation cable has impedance, which can cause measurement error.
This problem can be addressed through characteristics adjustment. For
details, refer to 3 Setting Characteristics.
