B - GENERAL SAFETY INSTRUCTIONS
ELECTRICAL SAFETY
Connection to the mains
Before you connect your machine, please make sure that:
— The meter, the overintensity protection system and the electrical installation are compatible with its maximum
power rating and its supply voltage.
— It can be connected, in a single-phase or three-phase with earth system, to a socket compatible with the plug on
its power cord (mobile equipment).
— If the cable is connected to a fixed point, the earth connection if there is one, may never be cut off by the system
offering protection from electric shocks.
— The switch, if there is one, is set to OFF.
Operating position
Arc welding and cutting requires strict compliance with safety requirements in respect of electrical currents (Order of
14.12.88).
Servicing
Before any internal checking or repairs, make sure that the machine has been disconnected from the electrical
installation by locking it out:
— Accidental connection of the cable of a fixed installation has been made impossible
— Cutting off by means of a fixed connection device relates to all poles (phase and neutral. It must be in the OFF
position, with no possibility of being put into service by mistake
Some machines have an HV.HF arc strike circuit (indicated by a plate). Never work inside such a box.
Any work on electrical installations must be carried out by persons qualified for that purpose (Decree 88-1056 of 14
November 1988, Section VI, Art 46).
Maintenance
From time to time, check that the machinery and its electrical accessories - connectors, flexible cables and extension
cords - are correctly insulated and connected.
Work for maintaining and repairing insulating enclosures and ducts may not be carried out in a haphazard manner
(Section VI, Art. 47 Decree 88-1056 of 14 November 1988).
— All repairs are to be carried out by specialists, or better yet, defective accessories should be replaced.
— Regularly check that the electrical connections are tight, with no heating.
Any fans placed in a circuit in which the air is laden with dust must be cleaned from time to time. That is because
the turbine may be fouled and become unbalanced, leading to increased noise and premature wear and tear of
bearings. Maintenance is required at least after every six months, depending on the type of dust treated.
La turbine est l'element essentiel de votre ensemble aspiration.
Un mauvais fonctionnement ou un mauvais entretien risque de remettre en cause la securite du poste de travail. on
veillera donc a maintenir le ventilateur en parfait etat.
votre installation a ete choisie par rapport a une application specifique. la turbine est caracterisee par un point de
fonctionnement debit d'aspiration (vitesse d'air dans les canalisations), pertes de charge.
conformement aux reglementations de la carsat et de l'inrs, un controle periodique de l'installation est necessaire
afin de verifier que celle-ci reste conforme au dossier des valeurs de references.
