Electrical Connection - Siko IV28M/1 Benutzerinformation

Mounting of the encoder
• Fixation either by screws and shaft clamping.
Ensure that the encoder is mounted without
strain.
• Do not exceed the values for the maximum axial
and radial shaft load.
• Ensure accurate shaft alignment. If shaft and
flange are not correctly aligned, strain on the
bearings will result, which will overheat and be
irreparably damaged.

4. Electrical connection

• Switch power off before any plug is inserted or
removed!
• Any wiring must only be carried out without
power.
• Provide stranded wires with ferrules.
• Check all lines and connections before switching
on the equipment.
• The encoder's and follower electronic's (eg.
control unit) operating supply must be switched
on simultaneously.
• Encoders with parallel output: Unconnected
signal lines must be provided with a resistor (eg.:
R = 10 kOhm) and connected to earth.
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 encoder or the con-
nection lines! Suitable wiring layout and choice
of cable can minimise the effects of interference
(eg. 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.
• 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.
• With output circuit LD5 cable length is 3 meters
max. In case of a cable prolongation (> 3m),
signals must be refreshed by a repeater and it

must be ensured that the encoder is connected
to 5V±5% supply voltage (for avoiding voltage
drop on cable).
