Electrical Connection - Siko MB320 Benutzerinformation

4. Electrical connection

• Wiring must only be carried out with power off!
• Check all lines and connections before switching
on the equipment!
Interference and distortion
All connections are protected against the effects
of interference. The location should be selected
to ensure that no capacitive or inductive in-
terferences can affect the sensor or the con-
nection lines! Suitable wiring layout and choice
of cable can minimise the effects of interference
(e.g. interference caused by SMPS, motors, cyclic
controls and contactors).
Necessary measures:
• Only screened cable should be used. Wire cross sec-
tion is to be at least 0,14mm², max. 0,5mm².
• Wiring to the screen and ground (0V) must be secured
to a good point. Ensure that the connection of the
screen and earth is made to a large surface area with
a sound connection to minimise impedance.
• The system should be positioned well away from
cables with interference; if necessary a protective
screen or metal housing must be provided. The
running of wiring parallel to the mains supply
should be avoided.
• Contactor coils must be linked with spark sup-
pression.
Supply voltage
The voltages depend on the sensor designs; they
are to be taken from the delivery documentation
and the identification plate.
e.g.: 24 VDC ±20%
Attention! When connecting sensor and follower
electronics, please do not exceed the max. admis-
sable cable length.

Please provide the channels with a 120 Ohm ter-
minating resistor.

1. Remove cable coating.
2. Open screening and twist it.
3. Strip stranded wires to a length of 5mm and
twist them.
4. Pinch stranded wires.

E6: Connection with plug pin and socket contact.
Plug mounting according to fig. 9.
1. Slip parts 6 to 10 over outer cable.
2. Strip cable.
3. Turn down screening.
4. Push part 5 onto ferrules.
5. Solder wires to part 3 (according connection
diagram).
6. Open spacer (part 4) and put it over ferrules,
squeeze and push it onto part 3. Slot and keyway
of parts 3 and 4 must align.
7. Press parts 6 and 5 together; cut prodruding
screening.
