Power supply control unit

Mains connection is by means of a permanently installed cable
(for example, NYM-J 3x1.5 mm²).

The control unit supply has been fused separately (maxi-
mum 16 A).
Route the mains cable through the cable gland at the left into

the control unit.
Connect the phase to terminal L and the neutral conductor to ter-

minal N.
Connect probe
Use a cable with 2 x 0.5 mm² to extend the probe cable. The maxi-
mum length of the probe cables is 50 m.

The probe cable is permanently installed and sufficiently pro-
tected from damage (for example, installed in a metal pipe).

The probe cable is not routed immediately next to or together
with cables carrying mains voltage.
Route the probe cable through the cable gland at the right into

the control unit.
Connect the probe cable to the corresponding terminals with the

designation "Sonde". Any polarity is permissible.
External unlocking
A pushbutton (normally open contact) can be connected to the two
terminals with the designation Unlock ("Entriegeln") which allows for
external unlocking of ÖWWG 3 from a distance of up to 100 m. The
maximum voltage at these terminals is 12 V. The pushbutton con-
nections must be voltage-free.
Voltage-free changeover contact
The product features a voltage-free changeover contact for transmis-
sion of the alarm condition to additional equipment (for example, ad-
ditional alarm unit ZAG 01).
The switching contact may be destroyed by voltage peaks when
inductive consumers are switched off.
Use commercially available standard RC combinations such as

0.1 µF/100 Ohm for inductive consumers.
