Electrical connection

4 Electrical connection
The electrical connection of the IVMI is made via the 5-pin plug M12x1 on the top of the
hous-ing.
The wiring of the IVMI depends on the version ordered. A distinction is made between fre-
quency and analogue output, as well as basic and optional wiring.
CAUTION
The electrical connection should only be carried out by a fully qualified electrician.
 De-energize the electrical system before connecting the
IVMI.
FIRE HAZARD DUE TO OVERHEATING OF THE DEVICE
Exceeding the specified limits will cause damage to the electronics. Without cur-
rent limiting, there is a fire hazard due to overheating of the device.
 Connect the IVMI only to a power source with limited
power.
FOR USE ON SHIPS OR OTHER MARITIME EQUIPMENT
induQ / IVMI devices do not offer isolation between Frame Ground (FG/PE)

and Signal Ground (GND/0V).
24 VDC power needs to be supplied via a Safety Extra Low Voltage (SELV) and
Limited Energy Circuit or SELV and Class II (double insulated) DC power supply.
Pulse and current signals coming from our device may only be connected to gal-
vanic insulated input ports.
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 accessories. The shielding is already connected with the knurled nut.
The maximum length of the connecting cable is 30 m.
SHIELDING REQUIRED
 Use only shielded connection cables.
 The shield of the connection cable
should not be connected to earth.
We recommend earthing the pipes directly before
and behind the IVMI ( Figure).
