1.3 ELECTRICAL CONNECTION
The electrical connection will be executed by connecting the
plug of the monobloc with the power supply by means of an
extension cable. (Fig. 1.3.a)
WARNING!! The electrical connections for the machine
should only be carried out by a qualified technician who will
be in charge of the preparation of the installation and who
should follow the indications below before connecting to the
power supply.
- ENSURE that the power voltage and frequency correspond to
that given on the data plate fixed on the side of the machine
Permitted Tolerances: +/- 10% of rated voltage +/-1% of con-
tinuous rated frequency.
- IT IS IMPORTANT to connect the equipment to an efficient
earthing system, fitted according to the standards in force
WARNING!! Do not use sockets or plugs that are not been
earthed.
- IN ORDER to protect the equipment from possible overloads
or short circuits, connection to the power supply must be made
by means of a thermomagnetic circuit breaker or a switch with
adequate dimensioned fuses.
- WE RECOMMEND, furthermore, that a differential switch (earth fault interrupter), with a high-sensitivity of at least 30 mA and
manual reset, be fitted upstream of the system.
CAUTION!! If the power supply is made by means of a generator make sure that the produced electrical energy is sufficient for
a sure start-up of the compressor.
For the size of safety device, the following should be taken into calculation:
-I n (rated current), indicated on the CE label, intervention curve "C"
-PROCEED to the electrical connection of the machine by following the colours of the wiring in the power supply cable:
green/yellow
=
PROTECTIVE CONDUCTING WIRE
blue
=
NEUTRAL
PROCEED to the electrical connection of the monobloc by means of a 16 mm power supply plug with two poles and ground wire
(IEC 309 INDUSTRIAL PLUGS).
1.4 DEINSTALLATION
For deinstallation, if any, follow steps A-E as given below.
A) DISCONNECT the power supply switch
B) REMOVE the plug or power supply cable from the main power supply.
C) REMOVE the equipment from its place, handling it with caution!
D) REPACK the equipment in its original packing if possible, taking care to replace all protective materials necessary to avoid
damage during transport.
E) FOR a new positioning and connection operations of the machine, proceed as previously described.
