Installation - Controller
The controller can be placed vertically and horizontally.
When you place it vertically, place the left side (from front side view) down.
Also, put the rubber feet on the bottom to the left side.
Use the same screws for securing the rubber feet.
Position of set screws for rubber feet
Make sure to keep the controller away from the peripherals for the air supply and
exhaust.
Controller Front side: 100 mm // Rear side: 150 mm
The rear side exhausts the hot air (approx. 10 deg C higher than ambient
temperature). Therefore, make sure that heat sensitive devices are not placed
near the outlet.
There must be room in front of the Controller so that the entire Controller can be
pulled outward.
There must also be room behind the Controller so that one can attach and remove
cables.
Use a base table that is at least 100 mm off the floor. Placing the Controller
directly on the floor could allow dust penetration leading to malfunction.
