1.1. Marking

1.2. Simplified analysis of potential sources of electric shocks

With the use of non-flammable products (as defined in the draft standard pr EN 50059:2016
Annex C), the risk of ignition is by definition nil or low, but on the other hand, these products
contain large quantities of water which quickly store quantities of energy sufficient to cause
electric shocks that would exceed the limits as defined in the draft standard EN50059-2016
Annexes A and B.

That is why the ISOCUBE insulating cabinet is equi pped with systems to prevent this type of risk.

tion environment, as defined according to the Standards IEC 60664-1and IEC 61010­1:2010.
2nd-degree pollution: Under normal use conditions, only non-conductive type pollution
arises. On a temporary basis, conduction caused by condensation may arise.

• The ISOCUBE isolating cabinet must be installed indoors, outside installation is strictly pro-
hibited.

• The hand-held electrostatic projection equipmen t can only be used in designated p ro­jection spots in accordance with Standard EN 12215 or under equivalent ventilation con­ditions.

• This equipment must not be used in a cab or an application room for solvent-based paints,
flammable liquids or ones which form explosive atmospheres.

• The use of this equipment in a work area for the application of electrostatic flammable
products or ones which form explosive atmospheres is dangerous.

• The ISOCUBE consists of the projection spray gun, the control module, the hose, the pump
and the product tank, which must be considered as a whole. Any technical change can
increase the stored electric energy in the whole set to a dangerous degree. It is strictly for

-

bidden to modify the equipment.

• Install the isolating cabinet away from any explosive zone.

• Servo-control the isolating cabinet to the “on” position of the booth’s suction fan.

• Correctly connect the control module to the installation’s ground terminal.

• Connect the pump and the product tank by means of an equipotential connecti on th at
is provided.

• The container of the spray product must be electrically conductive (metal).

• Connect all metal parts of the installation (paint pumps, containers, stools, spin coaters,
etc., which positioned within three meters of the spray gun to the ground.

• Keep the spray zone clean and free of all unnecessary components.

• The floor where the operator works must be antistatic (either unclad concret e floor ing or
a metal grating). Never cover the floor with an insulating covering. In potentially explosive
l

ocations, the floor assemblies must be antistatic, in accordance with

Standard EN 61340-4-1.

• The use inside the booth of an uncovered flame, any incandescent object, a device or
object capable of generating sparks other than the spray gun is strictly prohibited.
It is also prohibited to store in the vicinity of the booth or in front of the doors flammable
products or containers in which such products had been stored.

• The jars and cans containing paint or solvent must be systematically closed after use.

• The paint feed pump used must be rated with a maximum 1.8:1 ratio, and the pump’s air
supply must be equipped with a safety relief valve (sup plied) to limit pressure to a maxi

-

mum value of 6.5 bar.

• Inside an explosive zone, it is prohibited to use electrical or non-electrical equipment that
has not been certified, like electrical extension cables, surge protector power bars,
switches, etc.

1.6. Rules of use

• Verify the extraction ventilation system efficiency on a daily basis.

• Once a week, verify the adequate operations of the ventilation system servo controls.

• Correctly ground all metal parts of the booth, along with the parts to b e painted. The
resistance relative to the ground must be less than or equal to 1M

Ω (for a 500-V voltage
measurement). This resistance must be regularly checked and, in any case, at least once
a week.

• The operator must wear antistatic shoes in accordance with Standard EN 61340-4-3 and
moreover hold the Nanogun Airspray H

2O spray gun either with a bare hand or with anti-

static gloves or gloves modified so as to establish a direct contact between the butt and
his/her hand. The shoes intended to be worn by the operator must be compliant with

Index revision : A 8 7119

Standard ISO 20344. The measured insulation resistance must not exceed 100MΩ

• The protective clothing intended to be worn, including gloves, must be compliant with
Standard EN 1149-5. The measured insulation resistance must not exceed 100M

2. Description

This equipment is designed for the application of water-based or water- thinnable hy drosoluble
paint or varnish. The liquids sprayed must be non-flammable and highly conductive to
electricity.
To apply paints of this type electrostatically, the most simple and most effective way is to place
the liquid under high voltage, and electrically isolate the paint supply system.

The ISOCUBE isolating cabinet consists of:

•a Nanogun Airspray H2O spray gun (Item 1) (see RT Nr 7117),

• an electropneumatic box (Item 2) including the GNM 6080 control module (Item 3),

• A pneumatic piston pump (Item 4) supplying the spray gun,

• A 60kV short circuiter located on the top of the cabinet,

• a stirrer (Item 5) as an optional extra.

The ISOCUBE cabinet is equipped with safety systems that protect the operator against elec­trical shocks, by blocking access to the parts under high voltage.

3. Characteristics

(*) - The measurement of the viscosity of a water-soluble paint using a consistometric cup leads
to very significant errors. In effect, these paints are thixotropic: their viscosity decreases with the
intensity of agitation and with the time for which they are stirred. At rest, these paints are highly
viscous substances; in contrast, in movement, they become not very viscous substances. The
viscosities shown are indicative for paint stirred just before being measured with a cup.
(**) - Any other use is prohibited
