SUPPLY VOLTAGE

5.2.1 230V SINGLE-FASE POWER SUPPLY
Models:MULTIPLE 315; VM12; VM16; VM18; VM18H; VM53; VM53H
The appliances are provided with a standard 2P+T-10/16A German plug for connection to the electricity
mains. Insert the plug in a compatible power socket supplied by the mains.
ELECTRIC HAZARD! Before making the connection, always check to make sure the
electrical features of the system in the installation area are suitable.
5.2.2 400V THREE-PHASE SUPPLY VOLTAGE
Models: VM18; VM18H; VM53; VM53H; VM19; VM20; VM20TANDEM; VM1800; VM30
The appliances are provided with a CEE 3P+T/16A plug for connection to the electricity mains. Insert the plug in a compatible power socket supplied
by the mains.
ELECTRIC HAZARD! Before making the connection, always check to make sure the
electrical features of the system in the installation area are suitable and check the
direction of pump rotation.
5.2.3 CHECKING THE DIRECTION OF PUMP ROTATION IN 400V THREE-PHASE MACHINES
Procedure:
a) Check to make sure the voltage indicated on the machine nameplate corresponds to that of your mains supply (Fig. 2).
b) Insert the plug in the socket with the machine Off.
c) Check the oil level in the pump through the glass window provided on it (Fig. 1).
If the level is insufficient, follow the instructions described in the "CHANGING THE PUMP OIL" Chapter.
d) Adjust the "VAC" function on the control panel to a value between 3 and 5 (electromechanical versions), (Fig. 3A) 99% (digital versions with
sensor) (Fig. 3B) or 20 seconds (timed digital versions) (Fig. 3C).
e ) Lift the plexiglas cover after lowering the lid holder.
f) Switch the machine On by means of the main ON/OFF switch provided on the front of the machine.
g) Lower the cover to close it: the machine starts up automatically. With the pump rotating in the correct direction, the cover will remain lowered to
create vacuum (or an underpressure) inside the chamber; otherwise, the cover will rise again since air is blown in, not extracted from the
chamber. In this case, switch Off the machine immediately and have a specialist technician invert the power supply phases.
Check the direction of pump rotation every time the three-phase socket is changed!
ELECTRIC HAZARD!
Only specialist technicians must be allowed to invert the power supply phases.
