mounting width with crimp connection and 40 mm mounting width
with screw connection are available (screwdriver blade width:
3.5 mm, maximum torque: 0.8 Nm).
Use stranded conductor to facilitate handling of the front connector.
Ferrules are not required for screw connections, because the screw
terminals are provided with wire protection.
When the crimp contact is inserted in the plastic body of the front
connector, a click can clearly be heard. This indicates that the contact
is engaged. For jumpering or to correct the wiring, you can remove the
contacts with a releasing tool (see ordering information) without
having to pull out the front connector.
Ferrules are not required for screw connections, because the screw
terminals are provided with wire protection. You can use ferrules of
7 mm in length to DIN 46228. The maximum terminal area is
2
2 x 2.5 mm .

The crimp contacts must be ordered separately for these types of connector.
Caution
Only extra-low voltage 60 V DC with safety separation from
system voltage may be used for the 24 V DC supply and for the
24 V DC input signals. Safety separation can be implemented to
the requirements of, amongst other sources,
VDE 0100 Part 410/HD 384-4-41/IEC 364-4-41 (as functional
extra-low voltage with safety separation) or
VDE 0805/EN 60950/IEC 950 (as safety extra-low voltage SELV)
or VDE 0106 Part 101.
