FL SWITCH SFN ...

7267_en_01 PHOENIX CONTACT 9

Installation and Assembly/Removal

Install the FL SWITCH SFN ... on a clean DIN rail. To avoid contact resistance only use clean, corrosion-free DIN rails. End

clamps can be mounted on both sides of the module to stop the modules from slipping on the DIN rail.

Assembly:

1. Place the module onto the DIN rail from above. The up-

per holding keyway must be hooked onto the top edge

of the DIN rail.

2. Push the module from the front towards the mounting

surface.

3. Once the module has been snapped on properly,

check that it is fixed securely on the DIN rail.

Removal:

1. Insert a suitable tool (e.g., needle-nose pliers) into the

arresting latch and pull it down.

2. Pull the module slightly away from the mounting sur-

face.

3. Lift the module from the DIN rail.

Connect the DIN rail to protective earth ground using a grounding terminal block. The modules are grounded

when they are snapped onto the DIN rail. Connect protective earth ground with low impedance. Gigabit com-

ponents have a functional earth ground connecting screw on the top.
