CHAPTER 2. TRANSPORT AND INSTALLATION
Knocks and sudden movements must be
avoided when transporting the equipment. The
transport position will be shown by arrows on the
packaging. The packaging must be protected from
rain.
The GAR T equipment have lifting eyes. It is
best to use this system.
If the equipment is packed the wheels and
handle must be fitted before connecting it to the
mains. On the inside of the packing box you will find
everything necessary to assemble the equipment.
2.1. ELECTRICAL SUPPLY INSTALLATION
The electrical installation of the equipment
making up the system must be carried out by
specialised personnel according to the standards in
force.
The location must meet the following
requirements:
- Place: Dry and ventilated, far enough away
from the welding area in order to prevent the dust
and pollution caused by the welding process from
getting into the equipment. Never work in the rain.
The distribution panel where the machine has
to be connected, must be comprised of the following
elements:
DIFFERENTIAL SWITCH (ID):
Three-pole or two-pole
with minimum sensitivity of 300 mA. The aim of this
switch is to protect the personnel from direct or
indirect contact with electrical parts under voltage.
The differential switch is selected according to the
characteristics plate.
AUTOMATIC SWITCH (IA):
Three-pole or four-pole.
The instrument will be chosen according to the
characteristics plate. We advise choosing a slow type
Intensity-Time characteristic (Curve G), as false
trippings could occur due to transitory overloads.
All the equipment of the GAR T series have
two voltages (standard version at 220/380V),
therefore, it must be checked whether the voltage
chosen on the equipment coincides with the mains
voltage.
Figure 2. Change of Voltage.
CONNECTION AT 220 V
The standard equipment leave the factory with
the voltage selector at 380 V., in order to protect it
against negligence in the connection. To change it
to 220 V follow the instructions given on figure 2.
(The procedure will be the same in special voltage
cases):
1. Place screw T in position 22
°
. To connect the
equipment place handle in 220 V. position
Screw T should always be in place so as to avoid
deterioration in the equipment due to negligence in
the connection.
Connection to mains is made with the input
hose. This cable has four wires, three of which are
connected to the mains and the other (yellow, with
green border) must be connected to the earth intake
of the plug.
DO NOT FORGET TO CONNECT THE
EARTH INTAKE IN THE SOCKET
MAKE SURE THE MAINS VOLTAGE
COINCIDES WITH THAT ESTABLISHED IN
THE MACHINE
