Power supply (see electrical circuit diagram attached)
Power supply must be removed prior to any intervention on the station.
Connection to the power supply must be carried out by the exploiting.
Connect vacuum plant for medical use to a backed-up power supply.
Note: Power supply failure will interrupt the production of vacuum.
The HOSPIVAC and MINIVAC vacuum units are equipped with a dual power supply. It is
strongly recommended that each power supply comes from a different TGBT.
Refer to the motors or stations rating plates in order to insure that the voltage used on site is that required
by the equipment.
Connect the electric cabinet to power supply via the switch/breaker or the terminals L1–L2–L3–N + Earth,
using flexible power cord having conductor section capable of supporting the total power requirements
of all the motors that make up the unit (see table below).
Power cables must be protected upstream using a surge protection device in accordance
with current legislation and standards of your country.
Check all the electrical connections and tighten if necessary before switching on the system
A magneto-thermal starter as standard protects each motor.
Connect the synthesis alarm overview to a visual and/or audible alarm on the control unit.
The operation of a medical vacuum plant requires a power supply system to ensure the operation and safety
of the installation. In order to avoid the total loss of medical vacuum generation on, for example, a differential
disconnection due to a component grounding, two separate electric power supplies, distributed between the
motors, are installed.

of the wire type
of the length
of the room temperature
of the wire path
*There are two electric box on HOSPIVAC V2+V2/V3+V2/V3+V3 and TWIN version.
For HOSPIVAC G and TWIN G only

for motor Connect the earth wire. The cable having conductor section capable of supporting the power
requirements of one pump (see table above).
If the oil level detection or temperature safety option has been chosen, connect the sensors to the electric
cabinet as shown in the electrical diagram.
If vacuum pumps are equipped with the constant vacuum solenoid valve, connect it to the electric cabinet
as shown in the electrical diagram. (2 x 0.75 mm² +T)
For HOSPIVAC V2+V2/V3+V2/V3+V3 and TWIN G
Refers to the electrical diagram for made the connection between master box and piloted box.
Alarm report
The connection between Alarm report on automate units must be done by the person in charge of the
installation.
He must control the compliance wiring and proper operation during the final acceptance test.

Connections to the pneumatic network
Suction side
If the regulation mode with constant vacuum solenoid valve (FLEXO) is used on the HOSPIVAC V and G, the
values shown in the table below must be respected as minimum levels for the receivers in order to assure
correct operation.
Note: Higher levels than those indicated can only improve the quality of operation.

If ON/OFF regulation is chosen for the HOSPIVAC / MEDIVAC 1 / 2 /3 / G / V, the capacity must be calculated
using the formula laid down by the standard NF EN ISO 7396-1 (see § 2.2.).

For this secondary receiver, the connection can be realized using either rigid piping with a valve located
32
between the network and the receiver, or hose with a valve between the network and the hose. This hose,
fitted with a valve, is available as an option.
