Power supply (see electrical circuit diagram attached)
Power supply must be removed prior to any intervention on the plant.
Connection to the power supply must be carried out by the exploiting.
Connect HOSPIVAC CABIN to two backed-up power supplies.
The HOSPIVAC vacuum plants are equipped with a dual power supply. It is strongly
recommended that each power supply comes from a different TGBT.
Class I equipment: to avoid any risk of electric shock, this equipment must only be
connected to a power supply with a protective earth.
Refer to the plant rating plate in order to ensure that the voltage used on site is that required by the
equipment.
Connect the auxiliary electric box (or the control and auxiliary electric box if HOSPIVAC C3 E300) with
two flexible electrical cables with a minimum cross-section as shown in the wiring diagram and in the
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 motor 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, two separate electric power supplies (X and Y), distributed between the motors,
are installed.

* A D-curve circuit breaker protection must be installed for each power supply, upstream the electrical box.
** Indicative cable cross-sections according to the EN60204-1 standard
Even so, the sections shall be defined by taking contacts with the wire provider.
They depend on:
the wire type
the length
the room temperature
the wire path.
Supply the electric motors of the pumps by connecting the terminal box of each motor to the terminals
T1 - T2 - T3 of the contactor LU1 for motor A, LU2 for B and LU3 for C, etc. Connect the earth wire. The
cable section corresponds to the section for 1 vacuum pump in the table above.
If the oil level or temperature safety device (optional) has been selected, connect the probes to the
control box as shown in the wiring diagram.
If the pumps are equipped with a constant vacuum solenoid valve, connect them to the control box
according to the wiring diagram (2 x 0.75 mm² + E).
Follow the wiring diagram for the connections between the master box and the secondary box.
Alarm report
The connection between Alarm report and main automate 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.
When the air conditioning option is selected, an air conditioner disconnect contact is also available to
customers in the electrical box.

Connections to the pneumatic network
Suction side
With constant vacuum solenoid valve regulation mode (FLEXO), the values shown in the table below must
be respected as minimum levels for the receivers delivered separately in order to assure correct operation.
Note: Higher levels than those indicated can only improve the quality of operation.

Exhaust side
Ensure that the CABIN exhaust will not affect other systems in the surrounding area.
No air must be sucked in at least 3m around the vacuum CABIN exhaust.
