Foreword; Safety; Warnings - Helvi PC75 Manuel D'instructions

Thank you for purchasing our products. When
assembled and used correctly, our welding gene-
rators are reliable and long-lasting and will help
increase the productivity of your business with
minimum maintenance costs.
All these appliances were designed, manufactured
and tested entirely in Italy, in full accordance with
the European Directives of Low Voltage (2006/95/
EC) and EMC (2004/108/EC), by applying norms
EN 60974.1 (safety rules for electric material, Part 1:
source of welding current) and EN 60974-10 (EMC
Electromagnetic Compatibility) and are identified as
Class A products.
Class A appliances were not designed for use in
domestic environments in which power is supplied
through a public low-voltage grid; it is therefore po-
tentially difficult to ensure the electromagnetic com-
patibility of Class A appliances in such environments,
due to radiated and conduced disturbances.
These professional electric appliances must therefore
only be used in industrial environments, connected
to private power distribution cabins.
These generators are therefore not subject to the
European/International EN/IEC regulation 61000-
3-12 which defines the maximum levels of harmonic
distortion induced in the public grid of low-voltage
power distribution.
The installer or the user (if necessary, contact your
power distributor) is responsible for ensuring that
these appliances can be connected to a public low-
voltage grid.
Warning: the manufacturer refuses all re-
sponsibility in the event of unauthorized mo-
difications performed on its products.

WARNINGS

This manual contains instructions for the proper in-
stallation of the Electric Electronic Equipment (EEE)
you have just purchased.
The owner of an EEE must make sure that this
document is read and understood by welding tech-
nicians and their assistants and by maintenance
technicians.
Warning: Even when the ON/OFF switch of
the EEE is at "O", voltage from the power grid
is still present within the generator and in the
power cable. Prior to any internal inspection,
make sure the appliance has been discon-
nected from the power source (this means ta-
king a series of steps in order to separate the
appliance from the power source and to keep
it free from voltage).

FOREWORD

These power generators must only be used for the
cutting procedures described in this manual; they
must never be employed to recharge batteries, for the
thawing of water pipes, for the heating of buildings
by means of added resistances etc.
Compliance to RoHS Directive: We hereby declare
that this range of generators 3Ph described in this
manual is in accordance with RoHS EU Regulations
2002/95/CE of 27 January 2003 regarding the
restriction of the use of certain substances harmful
for human health present in Electric and Electronic
Equipment (EEE).
This symbol, applied to the welding generator
or to its packaging, indicates that, at the end
of its useful life, the product must not be tre-
ated as ordinary waste, but must be collected
separately from other waste and in accor-
dance with European Directive 2002/96/CE
of 27 January 2003 regarding the disposal
of waste electrical and electronic equipment
(WEEE). These must be collected separately
and disposed of in an environmentally com-
patible way.
As owner of an EEE product (Electrical Electronic
Equipment), you are responsible for contacting your
area dealers for information on authorized collectors.
Applying the above mentioned European Directive
improves the environment and our own health.
Warning: Welding, cutting and similar tech-
niques may be dangerous operations for
the worker and for anyone near the wor-
king area. Please carefully read the SAFE-
TY chapter below in order to reduce risks.

SAFETY

Electrical electronic appliances may never be used
without their panels and covers, as this may be
dangerous for the workers involved. Using the ap-
pliances without these protections may cause serious
damage to the appliances themselves.
These generators may be supplied by an electricity
generator, which must absolutely be equipped with
a diesel engine with a power higher than the power
required by the generator (see technical data table)
and output voltage of 400Vac +/- 10% - 3Ph –
50/60Hz.
