Installation on a standard mounting rail (SIDOOR ATD4xxW)
You need the SIDOOR standard rail mounting to mount a SIDOOR controller on a standard
mounting rail.
The SIDOOR standard rail mounting can be mounted on the controller in two different ways.
This enables the controller to be mounted both vertically and horizontally on a standard
mounting rail.
NOTICE
Material damage
The maximum screw depth when mounting a SIDOOR standard rail mounting on a
controller is 2.5 mm. The use of longer screws can result in damage to the controller.
For this reason, use only the fixing screws supplied for mounting the SIDOOR standard rail
mounting.
Proceed as follows to mount the standard rail mounting:
Steps
1. Select either a vertical or horizontal
orientation for mounting the control-
ler on the standard mounting rail.
2. Screw the SIDOOR standard rail
mounting tightly to the controller with
2 (M4 x 6) screws. Use the predrilled
holes in the controller for this pur-
pose.
