3 Mounting and installation
3.1 Mounting and removing the IP20 switch
Mount the switch on a clean DIN rail according to DIN EN 50 022 (e. g., NS 35 ... from Phoe-
nix Contact). To avoid contact resistance, only use clean, corrosion-free DIN rails. End
brackets (E/NS 35N, Order No. 0800886) can be mounted to the right and left of the switch
to stop the modules from slipping on the DIN rail.
To install:
1 Place the module onto the DIN rail from above. The upper holding keyway of the mod-
ule must be hooked onto the top edge of the DIN rail. Push the module from the front
towards the mounting surface.
Figure 3-1 Snap the switch onto the DIN rail
2 Once the module has been snapped on properly, check that it is fixed securely on the
DIN rail. Check whether the positive latch is facing upwards, i.e., snapped on correctly.
Removal:
1 Pull down the positive latch using a suitable tool (e.g., screwdriver). Then swivel the
bottom of the module away from the DIN rail slightly (1). Next, lift the module upward
away from the DIN rail (2).
