General
Concept
VersionsVersion 1:
This range of digital machines is remarkably flexible and readily adaptable to a wide
range of applications. These welcome features are due firstly to the modular product
design and secondly to the scope that the system gives for troublefree system expansion. High-quality components, protective plastic frames and a powder-coated aluminium
housing ensure excellent reliability and durability.
The auto-transformers are especially designed to meet the requirements of this range of
digital machines.
They allow the machines to be used with available mains voltages.

Safety
Converting the
mains voltage for
„Version 1“
WARNING! Work performed incorrectly can cause serious injury and damage.
The following activities must only be carried out by Fronius-trained qualified
personnel! Take note of the safety rules in the power source operating instructions.
WARNING! An electric shock can be fatal. Before opening the unit, turn the main
switch to the „0“ position and pull out the mains plug or disconnect the power
supply.
1.Turn the main switch on the auto-transformer to the „0“ position
2.Pull out the mains plug or disconnect the power supply
4.Disconnect the phase conductors (L1, L2, L3) in the „Setting 500 or 480 V (230 V)“
section
NOTE! Operating the auto-transformer with phase conductors only partially
reconnected can cause serious damage. When converting the mains voltage,
always make sure that all phase conductors are reconnected.
5.Connect the phase conductors (L1, L2, L3) in the „Setting 460 or 440 V (200 V)“
section
6.Check that all cables are securely connected to the terminal strip
7.Attach the auto-transformer cover
8.Cross out the mains voltage in the space above the rating plate and enter the mains
voltage you have set in the empty box
CAUTION! Operating the equipment at an incorrect mains voltage can cause
serious damage. The entered value must correspond to the mains voltage actually set.

Putting the machine into service
Safety
Preparing to
install
WARNING! Work performed incorrectly can cause serious injury and damage.
The following activities must only be carried out by Fronius-trained qualified
personnel! Take note of the safety rules in the power source operating instructions.
WARNING! An electric shock can be fatal. Only carry out work on the machine
when
- the mains switch is in the „0“ position,
- the machine is unplugged from the mains.

CAUTION! Beware of the danger of the trolley tipping over. Always place the
heavy auto-transformer at the bottom. This will reduce the danger of the trolley
tipping over as the centre of gravity is now lower.

Connecting the
auto-transformer
„Version 1“
WARNING! Operating the equipment incorrectly can cause serious injury and
damage. Read the following sections of the power source operating instructions
before starting the power source for the first time:
- Safety rules
- Putting the machine into service
- Putting the power source into operation
Connecting the
auto-transformer
„Versions 2 and
3“
The ventilation of the auto-transformer is a very important safety feature. When deciding
where to set up the system, ensure that cooling air can enter unhindered through the air
slots on the underside and escape through the slots in the sides.
1.If the auto-transformer mains cable needs to have a plug attached, fit a suitable
mains plug.
2.Switch the power source mains switch to the „0“ position
3.Turn the main switch on the auto-transformer to the „0“ position
4.Insert the mains plug of the auto-transformer and turn on the power supply.
5.Turn the main switch on the auto-transformer to the „I“ position
6.The auto-transformer is ready for use
Note: Operating the auto-transformer with phase conductors only partially
connected can cause serious damage. When connecting the connection cable,
always make sure that all phase conductors and the earth conductor are
connected.

Care, maintenance and disposal
GeneralUnder normal operating conditions the auto-transformer requires only a minimum of care
and maintenance. However, it is essential that certain important points are observed to
ensure the welding machine remains serviceable for many years to come.
WARNING! An electric shock can be fatal. Before opening the machine, turn off
the machine, disconnect the mains supply and attach a clearly legible and
comprehensible warning sign to prevent anyone switching it on again. Discharge electrolytic capacitors where necessary. The housing screws provide an
adequate PE conductor connection for earthing the housing. The screws must
never be replaced with different screws unless a reliable PE conductor connection is set up.
Every start-up
Every 6 months
Every 12 months
Disposal
-Check the mains plug and mains cable for damage
-Check that there is a gap of 0.5 m (1.6 ft.) all around the machine to ensure that
cooling air can flow and escape unhindered.
NOTE! Air inlets and outlets must never be covered, not even partially.
-Dismantle machine side panels and clean machine inside with dry reduced compressed air
NOTE! Risk of damage to electronic components. Do not bring the air nozzle
too close to the electronic components.
-If a lot of dust has accumulated, clean the cooling air ducts.
Carry out a safety inspection
(see the „Safety rules“ chapter in the power source operating instructions)
Dispose of in accordance with the applicable national and local regulations.
