3.Installatin Location

3.1 Environmental Tempetature

PLC use ambient temperature range: － 5℃ ～ 55℃. Ambient
temperature for a long time when over 55 ℃,Should choose a
well-ventilated place.

3.2 Installation Site

◆ Non-corrosive, flammable gases and liquids place.
◆ Strong vibration-free place.
◆ This PLC for the installation environment design II standards,
pollution level 2 applications.

3.3 Installation Position

Mount the PLC onto the cabinet backboard horizontally. You must
provide a clearance of at least 20cm, both above and below the unit, for
proper cooling. Never mount them to the floor or ceiling of an enclosure
or other directions. See the following figure. No heat generating
equipment should be around the PLC.

3.4 Installation Methord

DIN rail mounting
Generally you can mount the PLC onto a 35mm-wide rail (DIN), Open
the module at the bottom of the DIN card buckled，The bottom of the
module onto the DIN rail;
Rotating module close to the DIN guide rail, Close the DIN card clasp;
Double-check the module and DIN rail snap on DIN is closely fixed, as
the following figure
Screw fixing
Fixing the PLC with screws can stand greater shock than DIN rail
mounting. Use M3 screws through the mounting holes on PLC
enclosure to fix the PLC onto the backboard of the electric cabinet, as
the following figure.

3.5 Cable Connection And Specifications

Cable specifications
When wiring a PLC, use multi-strand copper wire and ready-made
insulated terminals to ensure the quality. The recommended model and
the cross-sectional area of the cable are shown in the following table.
Cable Recommended Wire NO. Conductor Cross-Section
AC power line（L、N） AWG12、18
Ground wire（ ）
Input signal wire（X） AWG18、20
Outout signal wire（Y） AWG18、20
Fix the prepared cable head onto the PLC terminals with screws.
Fastening torque: 0.5~0.8Nm.
◆ In order to safety (to prevent electric shocks and fire accident) and
reduce noise, PLC grounding terminals should be in strict accordance
with the national electrical code requirements grounding, grounding
resistance should be less than 100 Ω. Multiple PLC ground, should be
single-point grounding, ground loops can not form. As below:
1.0～2.0mm²
AWG12 2.0mm²
0.8～1.0mm²
0.8～1.0mm²
