Removal
CAUTION:
1.
Insert a suitable tool (e.g., needle-nose pliers) into the
arresting latch and pull it down.
Only qualified personnel may start up and operate
this device. Qualified personnel are persons
authorized to start up, ground and mark devices,
systems, and equipment according to the
standards of safety technology.

6.3
Pull the module slightly away from the mounting
surface.
Lift the module from the rail.
Power Connection
NOTE:
The FL SWITCH SFN… module is designed for
SELV and PELV operation according to
The switch is designed for SELV and PELV operation at
+24 V DC according to IEC 61140/EN 61140. Only SELV
and PELV according to the defined standards may be used
for supply purposes.
IEC 61140/EN 61140.
Snapping the switch onto a grounded DIN rail connects it to
WARNING:
A.)THIS EQUIPMENT IS SUITABLE FOR USE IN
CLASS I, ZONE 2, GROUPS A, B, C, AND D OR
NON- HAZARDOUS LOCATIONS ONLY.
B.) WARNING - EXPLOSION HAZARD -
the ground potential. In an environment particularly prone to
EMI, noise immunity can be increased by an additional low-
impedance connection to functional earth ground.
SUBSTITUTION OF COMPONENTS MAY
IMPAIR SUITABILITY FOR CLASS I, ZONE 2.
C.) WARNING - EXPLOSION HAZARD - DO
NOT DISCONNECT EQUIPMENT UNLESS
POWER HAS BEEN SWITCHED OFF OR THE
AREA IS KNOWN TO BE NON-HAZARDOUS.
Install the FL SWITCH SFN… on a clean DIN rail. To avoid
contact resistance use only clean, corrosion-free rails that
+
–
meet the EN 50022 standard. End clamps should be
mounted on both sides of the module to stop the modules
from slipping on the rail.

NOTE:
Connect the DIN rail to protective earth ground
using a grounding terminal block. The modules
are grounded when they are snapped onto the
rail. Connect protective earth ground with low
impedance. 1000 Mbps switches have a
protective ground connecting screw on top.
Assembly
Place the module onto the DIN rail from above. 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.
Once the module has been snapped on properly, check
that it is fixed securely on the rail.
