1.3 INDIVIDUAL PROTECTIVE DEVICES (IPD) TO BE USED

When handling the product, especially if already installed, always wear the following items of protective clothing: Accident-
prevention shoes, safety goggles, accident-prevention gloves and a leather apron or similar form of protection.
Every time maintenance or repair operations are performed on installed electric pumps, particularly those which are immersed in
dangerous liquids or septic tanks, all parts must be thoroughly cleaned and washed with water or specific products.

2 . DEVICE IDENTIFICATION

A metal identification plate stating all the product specifications is applied to the electric pump. Refer to the data on this plate when
seeking information or clarifications.

2.1 ATEX MARKING (potentially explosive environment)

0496
According to EN 60079-0 the plate coding summarises the following:
: product in conformity with the regulations with CE mark suitable for the product
0496 : identification number of the body that does the production check
: explosion-proof apparatus intended for use in potentially explosive environments;
II : (group) high-level protection system in potentially explosive environments;
2 : (category) electric pump intended for use in areas where explosive environments may originate from air and gas mixtures,
vapours, mists or air/dust mixtures
G : (gas) the electric pump is protected in areas where flammable gases, vapours or mists are present;
D : (dusts) the electric pump is protected in areas where flammable dusts are present;
Ex
: European Ex;
d
: electrical equipment for potentially explosive environments – explosion-proof casings "d";
k : non-electrical equipment for potentially explosive environments – protection by immersion in fluid "k";
c : non-electrical equipment for potentially explosive environments – protection by manufacturing safety standard "c";
IIB : (explosion group) type of potentially explosive environment in which the electric pump will be used;
T5 : corresponds to 100°C and is the maximum surface temperature that the electric pump can safely reach;
tD A21 : protection through holder; method A for constructions in area 21
IP68 : maximum degree of protection against the penetration of both solid bodies and fluids (30 m depth);
X : The pump installation must be carried out by qualified technical staff skilled in electrical and mechanical fields and trained to
deal with the hazards connected to places subject to risks of explosion. The wired box must also be suitable for the place of
installation

2.2 PLATE
