1.2 Assembly/Removal

1.2.1 Assembly and Removal of the LMS

Mount the LMS on a clean DIN rail according to DIN EN 50 022 (e.g., NS 35 ... from

Phoenix Contact). To avoid contact resistance only use clean, corrosion-free DIN rails.

Before mounting the modules, an end clamp (E/NS 35N, Order No. 0800886) should be

mounted on the left-hand side next to the LMS to stop the modules from slipping on the

DIN rail. The end clamp should only be mounted on the right-hand side once the LMS has

been mounted.

1.2.2 Assembly

1. Place the module onto the DIN rail from above (A). The upper holding keyway must be

hooked onto the top edge of the DIN rail. Push the module from the front towards the

mounting surface (B).

2. Once the module has been snapped on properly, check that it is fixed securely on the

DIN rail. Check whether the positive latches are facing upwards, i.e., snapped on

correctly.
