Electrical connection
The electrical connection of the DM04 is via the 5-pin plug M12x1 at the top of the housing.
The wiring of the DM04 depends on the ordered version. A distinction is made between frequency and ana-
logue output, as well as basic and optional wiring.
CAUTION! Electric current!
The electrical connection should only be carried out by a fully qualified electrician.
De-energize the electrical system before connecting the DM04.
CAUTION! Material damage and fire hazard!
Exceeding the specified limits will cause damage to the electronics. Without current limiting, there is
a fire hazard due to overheating of the device.
Connect the DM04 only to a power source with limited power.
Optional wirings:
Depending on the version, an analogue output can be optionally connected.
Connecting cable:
Suitable connection cables with moulded coupling socket are available in various lengths included in the
range of SIKA accessories. The shielding is already connected
with the knurled nut.
IMPORTANT! Shielding required!
Use only shielded connection cables.
The shield of the connection cable should not
be connected to earth.
We recommend to earth the pipes directly before and behind the
DM04 (
Figure).
IMPORTANT NOTICE:
Pay attention to the temperature resistance of the connecting cable (§ 9 “Technical data) at high me-
dia temperatures.
If the temperature resistance is smaller than the medium temperature, the cable may not be directly
laid on the pipe.
Connection 5-pin plug M12x1:
Screw the coupling socket of the connection cable to the plug of the DM04.
Tighten the knurled nut of the coupling socket with a maximum torque of 1 Nm.
