2 INSTALLATION

Installation should be performed only by expert
personnel authorised by the manufacturer.
During installation, ensure that the power source
is disconnected from the mains.
The multiple connection of power sources (series
or parallel) is prohibited.
2.1 Lifting, transport & unloading
- The equipment is provided with a handle for hand transportation.
- The equipment is not equipped with specific lifting elements.
Use a fork lift truck paying attention during operations in
order to prevent the generator from tipping over.
Do not underestimate the weight of the equip-
ment: see technical specifications.
Do not move or position the suspended load
above persons or things.
Do not drop or apply undue pressure on the
equipment.

2.2 Positioning of the equipment

Keep to the following rules:
- Provide easy access to the equipment controls and connec-
tions.
- Do not position the equipment in very small spaces.
- Do not place the equipment on surfaces with inclination
exceeding 10° from to the horizontal plane.
- Position the equipment in a dry, clean and suitably ventilated
place.
- Protect the equipment against pouring rain and sun.

2.3 Connection

The equipment is provided with a power supply cable for con-
nection to the mains.
The system can be powered by:
- three-phase 400V
Operation of the equipment is guaranteed for volt-
age tolerances up to ±15% with respect to the
rated value.
22
The equipment can be powered by a generating set
guarantees a stable power supply voltage of ±15%
with respect to the rated voltage value declared by
the manufacturer, under all possible operating condi-
tions and at the maximum rated power.
Normally we recommend the use of generating
sets with twice rated power of a single phase
power source or 1.5 times that of a three-phase
power source.
The use of electronic control type generating sets
is recommended.
In order to protect users, the equipment must be
correctly earthed. The power supply voltage is pro-
vided with an earth lead (yellow - green), which
must be connected to a plug provided with earth
contact.
The electrical connections must be made by
skilled technicians with the specific professional
and technical qualifications and in compliance
with the regulations in force in the country where
the equipment is installed.
The power source supply cable is provided with a yellow/
green wire that must ALWAYS be earthed. This yellow/green
wire shall NEVER be used with other voltage conductors.
Verify the existence of the earthing in the equipment used
and the good condition of the sockets.
Install only certified plugs according to the safety regula-
tions.
2.4 Installation
Connection for MMA welding
The connection shown in the figure produces
reverse polarity welding. To obtain straight polar-
ity welding, reserve the connection.
- Connect the earth clamp (1) to the negative socket (-) (2) of
the power source.
- Connect the electrode holder (3) to the positive socket (+) (4)
of the power source.
