GENERATION IN AC (ALTERNATING CURRENT)
Make certain of the efficiency of the ground
connection (12) - See page M20 -.
Position the G.F.I. switch to ON.
☞
Voltage is now immediately available to the AC
sockets.
Verify that the voltmeter displays the nominal voltage
value + 10%.
Connect the electric devices to be powered to the
AC sockets, using suitable plugs and cables in
good condition.
It is strictly forbidden to connect the group to
the public mains and/or to any other source
of electric power.
WARNING
☞
Verify that the electrical characteristics (voltage/
frequency/power) of the device being powered are
compatible with those of the generator.
Low frequency and/or voltage can irreparably
damage some electrical devices.
Verify that the ground lead of the electrical appliance/
tool to be powered is correctly connected to the
terminal of the plug.
☞
For double insulation devices with the symbol
, the plug’s ground terminal does not need
to be grounded.
THERMAL PROTECTION
The monophase outputs are protected against
overloads by the thermal protection (59B).
When the rated current is exceeded, the protection
intervenes to cut off the voltage to the AC socket.
. Note: the intervention of the thermal protection is
not instantaneous, but reacts according
to an overcurrent/time characteristic, whereby the
greater the overcurrent the quicker the intervention.
In case of intervention by the protection device,
verify that the total power for the loads connected
does not exceed the declared rating and decrease
if necessary. Disconnect the loads and wait a few
minutes to allow the thermal protection to cool down.
Before resetting by pressing
the central button and then
connect the load again.
If the protection should
intervene again, replace it with another one with
matching intervention current specifications and/or
contact the Service Department.
. Note: do not forcibly hold the central button of the
thermal protection device to prevent its intervention,
as this could irreparably
damage
the unit’s
alternator.
☞
Note: the three phase output does not require
any protection against overcurrents, since it uses
a self-protecting asynchronous type alternator.
GROUND FAULT INTERRUPTOR SWITCH
The high-sensitivity ground fault interruptor switch
[G.F.I.] (30mA) (D), guarantees protection against
indirect contacts due to faulty ground currents .
When the G.F.I. switch picks up a faulty ground
current that is higher than 30mA, it intervenes by
immediately cutting off voltage to the AC sockets.
In case of intervention by this protection
device, reset the G.F.I. switch by moving
the lever to the ON position. In case of
another intervention, verify that there are
no faults in the tools connected, or
replace the G.F.I. switch with another
one of matching specifications and/or contact the
Service Department.
☞
Notes: Verify the operation of the G.F.I. switch
at least once a month by pressing the TEST button.
The generator must be running and the G.F.I. lever
in the ON position.
SIMULTANEOUS USE
The welder’s alternator permits the simultaneous
use of auxiliary power and welding current. The
auxiliary power available to the AC plugs (15)
diminishes as the welding current drawn increases.
The table on page M52 TECHNICAL
SPECIFICATIONS shows the amount of auxiliary
power available as the welding current varies.
COMBINED USE
The output available from the various auxiliary power
sockets is limited, not only by the declared output of
the unit but also by the capacity of each individual
socket.
