Mounting and commissioning
ÖWWG 3 21
Power supply
Connect the oil/water alarm unit to mains by means of a permanently
installed cable such as NYM-J 3 x 1.5 mm
2
.

Route the power supply cable through the cable gland at the left
into the control unit. The phase must be connected to
terminal L, the neutral conductor to terminal N.

The control unit supply should have a separate fuse (maximum
16 A).

The probe cable must also be permanently installed; route it
through the right cable gland into the control unit and connect it
to the terminal with the designation "Probe" ("Sonde"). You do
not have to ensure a specific polarity.

Standard shielded cable 2 x 0.5 mm² can be used to extend the
probe cable. The maximum length of the extension cable is
50 m.

Do not route the probe cable next to mains cables; danger of
interference.

Protect the probe cable from damage; use metal pipes, if
required.
External unlocking
A pushbutton (normally open contact) can be connected to the two
terminals with the designation Unlock ("Entriegeln") in the control unit
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 connections must be voltage-free.
Output
The output signal of the oil/water alarm unit is made available via a
voltage-free relay contact (changeover contact). If no error condition
is present, the relay is -energised; in case of an alarm, the relay is
de-energised.
NOTICE 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.
