2 Mechanical Installation Installation Environment Requirements When installing the programmable controller on the guide rail, take the operability, maintainability, and environment adaptation into account. Item Specifications Operating environment Places without corrosive or inflammable gas or severe conductive dust Altitude Maximum 2,000 m (80 kPa) Pollution degree Interference immunity 2 kV on power supply line (IEC 61000‑4‑4)
Page 22 Item Specifications Installation position and limit Installation position: The PLC can be installed in four directions. For details, see " 2.2 Installation Position Requirements " on page 21 Limit: Horizontal installation: Input derating: When the ambient ● temperature is 45°C, the PLC can work at full load.
Page 23: Installation Position Requirements
Item Specifications Continued (To be continued) Output derating: When the ambient ● temperature is 45°C, the PLC can work at full load (that is, the total current of the eight outputs not higher than 2 A). When the ambient temperature is 55°C, the total current of simultaneously active outputs shall be reduced to 50% (that is, the total current of the eight outputs not higher...
Page 24: Other Installation Positions
Note Keep the PLC away from high‑temperature heating sources (heater, transformer, large resistor, etc.) by at least 100 mm. ■ Other installation positions For other installation positions, the same clearance requirements as the optimal installation position apply. Other installation positions are shown in the following figure.
Page 25: Installation Precautions
In case of vertical installation: Install the PLC below all I/O modules. ● Hold the cables with a cable duct to prevent the weight of cables being ● applied to the lower end plate. Failure to comply may cause displacement of the PLC from the DIN rail, leading to maloperation of the PLC.
Page 26: Installation Dimensions
Installation Dimensions The installation dimensions (in mm) are shown in the figure below. Installation Methods The master is mounted onto a DIN rail that complies with IEC 60715 (width: 35 mm, thickness: 1 mm). The dimensions (unit: mm) are shown below. When installed on a DIN rail other than the recommended one (especially the one whose thickness is not 1.0 mm), the module will not fit in place as the mounting hook does not work.
Page 27 2. Make sure the DIN rail mounting hook of the master is locked. The locked and unlocked states of the mounting hook are shown below. If the mounting hook is pressed down, it is locked. ● If the mounting hook is lifted up, it is unlocked. ●...
Page 28: Removing The Module
Install an DIN rail end plate to both sides of the master or module. To mount the end plate, hook the bottom of it to the bottom of the DIN rail, rotate the end plate to hook the top of it to the top of the DIN rail, and then tighten the screw to lock the end plate in place, as shown below.

Material Name Applicable Cable Size Tubular lug 0.75 If other tubular lugs are used, crimp them to twisted cables. The following figure shows requirements of the shape and size.
Page 35: Cable Connection
Cable Connection ■ RS485&RS232 communication The RS485 communication port and the RS232 communication port share the same terminal block, with RS485 communication port on the left and RS232 communication port on the right. The signal on the left side of the terminal is RS485 communication, and the signal on the right side is RS232 communication.
Page 36 Check the silk print on both sides of the terminal to prevent wrong cable connection. Do not connect the GND cable to the I/O terminal on the lower side. Failure to comply can lead to short circuit and damage the components. ■...

5 Operation and Maintenance Program Run and Stop After writing a program while the PLC is in the "STOP" state, execute the shutdown operation as described in the following table. Status Operation 1. Set the system to the "RUN" state. To run the system 2.
Page 39 5. After successful download, the RUN indicator blinks slowly at 1 Hz and the PLC enters the "STOP" state. Then, remove the SD card. If the ERR indicator blinks slowly, it is indicated that the download has failed. Check whether the downloaded file is applicable to the PLC model and whether the login password of the downloaded file is the same as the login password of the PLC.
