NOSHOK 1800 Series Attachable Loop-Powered Indicator - Manual (Page 6)

General instruction for change of the angle-type plug assignment:
Remove the coupling insert by means of a screw driver at the position indicated (arrow).
Change the assignment according the notes of the respective input signal.
Latch coupling insert in cover. You have a choice between 4 different orientations – each of
them spaced 90°.
Put on angel-type plug and connect plugs using the long screw delivered (do not forget seals).
3.2 Connection example
Please take care that you must not exceed the limits of the voltage and of the maximum current
of the switching outputs (not even for a short period of time). Please take extreme care when
switching inductive loads (like coils or relays, etc.) because of their high voltage peaks,
protective measures to limit these peaks have to be taken.
When switching large capacitive loads a series resistor for current limitation needed, because
of the high turn-on-current of high capacitive loads. The same applies to incandescent lamps,
whose turn-on-current is also quite high due to their low cold resistance.
