Installation method

Mount the controller on a DIN rail. In case the DIN rail produces significant vibrations, mount the
controller on an appropriate metal plate.
Do not place any equipment that generates excessive heat or noise in the vicinity of the controller.
Warning
Check and reexamine the means of ventilation if the ambient temperature of the controller exceeds
50°C (122°F).
Mounting the controller on a DIN rail
Use a DIN rail of 35mm (1.38in.) in width. Use the end
plates to secure the controller mounted on the DIN rail.
1. Engage the hook on the back of the controller over the
DIN rail by pulling down the controller's DIN lever, and
push the controller until the DIN lever locks in place.
2. Secure each end of the controller using the end plates.
Installing the controller with screws
Install the controller on a metal plate and secure it using
two screws (M3 or M4, two pieces).
There should be no gap between the controller and plate.
The screws are not included in the package.
Removing the controller from the DIN rail
1. Use a flat-head screwdriver to pull down the DIN lever
until it locks in place.
Pull the DIN lever with a force of 10 to 20N (2.2 to
4.41lb.).
Applying excessive force may damage the DIN lever.
2. Raise the controller upward to remove from the DIN
rail.
