Connection To The Electrical Supply; Usage Norms - CEA RAINBOW 200 HF Manual De Instrucciones

with the technical prescriptions of the
EN 50199 standard and is foreseen to
be used in all industrial spaces and
not in spaces for domestic use. If elec-
tromagnetic disturbances should
occur, it is the user's responsibility to
resolve the situation with the technical
assistance of the producer. In some
cases the remedy is to schormare the
welder and introduce suitable filters
into the supply line.
MATERIALS AND DISPOSAL
• These machines are
built with materials that
do not contain sub-
stances that are toxic or
poisonous to the opera-
tor.
• During the disposal phase the
machine should be disassembled and
its components should be separated
according to the type of material they
are made from.
HANDLING AND STOCKING
COMPRESSED GASES
• Always avoid contact
between cables carry-
ing welding current and
compressed gases cyl-
inder and their storage
systems.
• Always close the valves on the com-
pressed gas cylinders when not in
use.
• The valves on Inert gas cylinder
should always be fully opened when in
use.
• The valves on flammable gases
should only be opened full turn so that
quick shut off con be mode in an
emergency.
• Care should be taken when moving
compressed gas cylinders to avoid
damage and accidents which could
result in injury.
• Do not attempt to refill compressed
gas cylinders, always use the correct
pressure reduction regulators and

Installation
The installation site for the system must
be carefully chosen in order to ensure its
satisfactory and safe use.
The user is responsible for the installa-
tion and use of the system in accor-
dance with the producer's instructions
contained in this manual.
Before installing the system the user
must take into consideration the poten-
tial electromagnetic problems in the
work area. In particular, we suggest that
you should avoid installing the system
close to :
• signalling, control and telephone
cables
• radio and television transmitters and
receivers
• computers and control and measure-
ment instruments
• security and protection instruments
Persons fitted with pace-makers, hear-
ing aids and similar equipment must
consult their doctor before going near a
machine in operation. The equipment's
installation environment must comply to
the protection level of the frame i.e. IP
23 (IEC 529 publication). This system is
cooled by means of the forced circula-
tion of air, and must therefore be placed
in such a way that the air may be easily
sucked in and expelled through the
apertures made in the frame.

Before connecting the welder to the
electrical supply, check that the
machine's plate rating corresponds
to the supply voltage and frequency
and that the line switch of the welder
is in the "O" position. Only connect
the welder to power supplies with
grounded neutral. Only connect the
welder to power supplies with
grounded neutral.
This system has been designed for
nominal voltage V.230 50/60Hz. It can
however work at V.220 and V.240 50/
60Hz without any problem. Connection
to the power supply must be carried out
using the tripolar cable supplied with the
system, of which:
• 2 conducting wires are needed for
connecting the machine to the supply
• the third, which is YELLOW GREEN in
colour is used for making the
"EARTH" connection.
Connect a suitable load of norma-
lised plug (2p + t) to the power cable
and provide for an electrical socket
complete with fuses or an automatic
switch. The earth terminal must be
connected to the earth conducting
wire (YELLOW-GREEN) of the supply.
Table 2 shows the recommended load
values for retardant supply fuses chosen
according to the maximum nominal cur-
rent supplied to the welder and the nom-
inal supply voltage.
NOTE 1: any extensions to the power
cable must be of a suitable diameter,
and absolutely not of a smaller diameter
than the special cable supplied with the
machine.
NOTE 2: It is not advisable to plug up
the welder to motor-driven generators,
as they are known to supply an unstable
voltage.
