5. 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:
• Use of screened connection cable with trunk
cable in pairs. Pairs to be allocated differential-
signal wise (D+, D-), (T+, T-), (A, /A), (B, /B)
(Recommendation: encoder/-resolver line from
Messrs. LAPP-Kabel, 5*2*0,14²+2*0,5², type-no.:
70388728).
• Wiring to the screen and ground (GND) 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 sensor 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.
