3.4 Installation method
The PLC must be installed horizontally on the back panel of the
electrical cabinet. Install it up and down and keep the distance between
the PLC and the equipment or cabinet wall above and below not less
than 20cm. Installation in other directions is not conducive to heat
dissipation of the PLC, and there should be no heating equipment
under the PLC.
Make holes in the panel according to the size of the opening. The
MCCD series display control integrated PLC is embedded from the
front of the panel, and the text display is fixed with four randomly
equipped mounting brackets. See the operation diagram below:
3.5 Cable connections and specifications
When wiring products, it is recommended to use multiple copper wires
and prefabricate insulated terminals to ensure the quality of wiring. The
sectional area and type of the recommended conductor are shown in

For security (to prevent electric shock and fire accident), and reduce
the noise, the module of grounding terminal shall be in strict
accordance with the national electrical code requirements, grounding
resistance should be less than 0.1 Ω. When grounding multiple
modules, single point grounding should be adopted, and the ground
wire cannot form a circuit. As shown in the figure below:
