Electrical connection can only be made when de-energized!
For switching supply sources, it is necessary to check that the input is galvanically separated
from the network side and that they are fitted with a filter suppressing the conforming inter-
ference (ter a – collectively oscillate against ground potential), or the interference
is removed in another manner.
In case of strong ambient electromagnetic interference, paralleling of conductors with power distribution,
or for distribution to distances over 30 m, we recommend using shielded cable.

Sensors DLS-35 with type of cable outlet A, B, V or H are connected to assessing units perma -
nently connected by PVC cable. Design diagrams are provided on page 7.
Sensors DLS-35 with connection method type C (see page 7) are connected to assessing units
by means of a connector socket with compression cable (length 2 or 5 m), or by means of a con-
nector socket without cable (see accessories). In this case the cable is connected to the inside
pins of the socket according to Figure 15. The recommended diameter of this cable is 4 to 6 mm
(the recommended cross-sectional area is 0.5 to 0.75 mm
2
).

lectrical connection
A sensor with NPN or PNP output can be loaded only by resistive or inductive load. The positive
pole of the supply voltage (+U) is connected to the brown wire BN or pin connector no.1, the nega-
tive pole (0 V) is connected to the blue wire BU or pin connector no. 3 and load on the black wire
BK or pin connector no. 4 . The capacitative loads and low resistance loads (bulb) is evaluated by
the sensor as a short circuit.
Connection diagrams are listed in Figures 13 and 14.
