All installation, connection, commissioning, servicing and repair
work on P1V-S motors must be carried out by qualified personnel
taking account of the following:
• These instructions.
• Notices on the motor.
• All other planning documents, commissioning instructions
and connection diagrams associated with the application.
• Provisions and requirements specific to the application.
• Applicable national/international regulations (explosion pro-
tection, safety and accident prevention).
Real life applications
P1V-S motors are designed to provide rotary movement in
industrial applications, and should only be used in accordan-
ce with the instructions in the technical specifications in the
catalogue, and within the operating range indicated on the motor
housing. The motors meet the applicable standards and require-
ments of the Machinery Directive 2014/34/EU (ATEX)
The motors must not be used as brakes in
explosive atmospheres.
Braking involves driving the motor against the direction of rota-
tion for which the motor is supplied with compressed air. The
motor is then operating as a compressor, and there is a cor-
responding increase in temperature.
The motors must
not
be used underground in mines
susceptible to firedamp and/or combustible dust. The motors
are intended for use in areas in which explosive atmospheres
caused by gases, vapours or mists of combustible liquids, or air/
dust mixtures may be expected to occur during normal use (infre-
quently)
Checklist
Before using the motors in a potentially explosive atmosphere,
you should check the following:
Do the motor specifications match the classification of the area of
use in accordance with Directive 94/9/EG
(previously ATEX 100a)?
• Equipment group
• Equipment category
• Zone
• Temperature class
• Max. surface temperature
1. When installing the motor, are you certain that there is no
potentially explosive atmosphere, oil, acids, gases, vapours
or radiation?
2. Is the ambient temperature as specified in the technical data
in the catalogue at all times?
3. Are you certain that the P1V-S motor is adequately
ventilated and that no additional heat is added
(for example in the shaft connection)?
4. Are all the driven mechanical components ATEX certified?
Additional safety instructions for installation in explosive atmospheres
Serious, even fatal, damage or injury may be caused by the hot moving parts of the P1V-S motors in the presence of
explosive gas mixtures and concentrations of dust.
Installation requirements in potentially explosive
atmospheres
• The temperature of the supply air must not exceed the
ambient temperature.
• The P1V-S may be installed in any position.
• An air treatment unit must be attached to the inlet of the
P1V-S air motor.
• In a potentially explosive atmosphere, none of the
motor ports may be blocked because this may cause an
increase in temperature. The air from the port must be taken
to the silencer or, preferably, outside the potentially explosive
area.
• The P1V-S motor must be connected to ground at all
times, through its support, a metallic tube or separate con-
ductor.
• The outlet of the P1V-S motor must not open within a poten-
tially explosive area, but must be passed to the
silencer
or, preferably, removed and released outside the potentially
explosive area.
• The P1V-S motor may only drive units that are ATEX certi-
fied.
• Ensure that the motor is not exposed to forces greater than
those permitted in accordance with the catalogue.
Measuring the temperature on the outside of the
P1V-S motor (only when used in potentially explosive
areas)
During the commissioning process, it is essential to measure
temperature increases at the indicated positions on the outside
of the P1V-S motor.
These measurements can be taken using standard
thermometers.
Checking the motor during operation
The motor must be kept clean on the outside, and a layer of dirt
thicker than 5 mm must never be allowed to form.
Strong solvents should not be used for cleaning, because they
can cause the seal (material NBR/FPM) around the drive shaft to
swell, potentially increasing the temperature.
