Electrical connection

5 Electrical connection
The electrical connection of the VMI is made via the 5-pin plug M12x1 on the top of the hous-
ing.
The wiring of the VMI depends on the version ordered. A distinction is made between fre-
quency and analogue 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 VMI.
CAUTION! Material damage and fire hazard!
Exceeding the specified limits will cause damage to the electronics. Without current lim-
iting, there is a fire hazard due to overheating of the device.
 Connect the VMI 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 in-
cluded in the range of SIKA accessories. The shielding is already connected with the knurled
nut. The maximum length of the connecting cable is 30 m.
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 VMI ( Figure).
IMPORTANT NOTICE:
Pay attention to the temperature resistance of the connecting cable ( § 9 "Technical
data") at high media 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 VMI.
 Tighten the knurled nut of the coupling socket with a maximum torque of 1 Nm.
