3.3.2 Mains connection
The mains connection (Fig. 3-4, 11, Pos. G) is
designed for a mains cable which contains a European
appliance connector on the device side.
A mains cable is supplied with the unit. If the plug is not
compatible with your wall socket, you have to get a suit-
able mains cable:
• Three-conductor cable with protective ground
• Conductor cross-section 3 × 1.5 mm

1 Connect the European appliance connector of the
mains cord with the mains connection of the unit
2 Connect the plug of the mains cable with the wall
socket
NOTE:
If the unit is installed in a switching cabinet, the
mains power can be supplied via a switchable central
power distributor.
3.3.3 Ground
The ground screw (Fig. 3-4, 11, Pos. I) can be used to
connect the Vacuum Gauge Controller with the protective
ground of the pumping station.
1 If required: Connect the protective ground of the
pumping station with the ground screw. Use a pro-
tective conductor.
3.3.4 SENSOR
The SENSOR connection is used to connect the sensors.
For each channel, there are two connections available
which are connected in parallel: An 8-pin RJ45 appliance
socket and a 15-pin D-Sub appliance socket. See
Fig. 3-4, 11, Pos. A…C.
