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.

◆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:

MC200E Lord module provides 5 V dc logic power supply (5 V/GND)
and 24 V dc logic power supply (24 V/GND) for self and all extension
module. At the same time MC200E Lord module can also provide 24 V
dc power supply (24 V/COM), the 24 VDC can input point or other
equipment for power supply, MC200E series provide active I/O
extension module, the 5 V/GND, 24 V/GND, 24 V/COM output can be
used as the subsequent passive extension module of power supply.

8. Power operation and routine maintenance
8.1 Power operation
After the connection, item by item, check to ensure that no foreign
connections fall into the cabinet inside,heat flow
1．Switch on the POWER of the controller, POWER light should be light;
2．Start the PC software programming, Download the user program
will be programmed into the controller;
3．Download program calibration finished.
8.2 Routine Maintenance
Routine maintenance checking should pay attention to the following:
1．Ensure working environment clean and tidy, controller, avoid foreign
body in dust into machine;User equipment
2．To maintain good ventilation controller；
3．All wiring connections and terminals, fixed tightly in good condition
4. Observe the indicator light controller, observe LCD display screen
and state information.
9. The common problems and solutions
When the controller can not work normally, please check in turn:
1. Power line connection and protection of electrical switches and
related conditions, ensure controller has been reliable power supply；
2. The connection of user terminals is strong;
3. Refer to the fault record. If the above checks are done and when
confirmed controller still unable to work, Can refer to the table and
working status of the controller for analysis
