4 • General safety regulations OptiFlex 2 V
The OptiFlex 2 V Fresh powder system is state of the art equipment that
conforms to the recognized technical safety regulations and is designed
for normal powder coating applications.
Any other use is considered non-compliant. The manufacturer shall not be
liable for damage resulting from such use; the user bears sole responsibil-
ity for such actions. If the OptiFlex 2 V is to be used for other purposes or
other substances outside of our guidelines then Gema Switzerland GmbH
should be consulted.
Observance of the operating, service and maintenance instructions speci-
fied by the manufacturer is also part of conformity of use.
The relevant accident prevention regulations, as well as other generally
recognized safety regulations, occupational health and structural regula-
tions are to be observed.
Furthermore, the country-specific safety regulations also must be ob-
served.
Additional safety and operation notices can be found on the accompany-
ing CD or on the homepage www.gemapowdercoating.com.
Start-up is forbidden until it has been established that the OptiFlex 2 V
fresh powder system has been set up and wired according to the EU
guidelines for machinery.
Unauthorized modifications to the OptiFlex 2 V fresh powder system ex-
empt the manufacturer from any liability from resulting damages or acci-
dents.
The operator must ensure that all users do have the appropriate training
for powder spraying equipment and are aware of the possible sources of
danger.
Any operating method, which will negatively influence the technical safety
of the powder spraying equipment, is to be avoided.

For your own safety, only use accessories and attachments listed in the
operating instructions. The use of other parts can lead to risk of injury.
Only original Gema spare parts should be used!
Repairs must only be carried out by specialists or by authorized Gema
service centers. Unauthorized conversions and modifications can lead to
injuries and damage to the equipment and invalidate the Gema Switzer-
land GmbH guarantee.
The connecting cables between the control unit and the spray gun must
be installed in such a way, that they cannot be damaged during the op-
eration. Please observe the local safety regulations!
The plug connections between the powder spraying equipment and the
mains should only be removed when the power supply is switched off.
All maintenance activities must take place when the powder spraying
equipment is switched off.
The powder coating equipment may not be switched on until the booth is
in operation. If the booth stops, the powder coating device must switch off
too.
The control units for the spray guns must be installed and used in zone
22. Spray guns are allowed in zone 21.
Only original Gema OEM parts are guaranteed to maintain the explosion
protection rating. If damages occur by using spare parts from other manu-
facturers, the warranty or compensation claim is void!
Conditions leading to dangerous levels of dust concentration in the pow-
der spraying booths or in the powder spraying areas must be avoided.
There must be sufficient technical ventilation available, to prevent a dust
concentration of more than 50% of the lower explosion limit (UEG = max.
permissible powder/air concentration). If the UEG is not known, then a
value of 10 g/m³ should be considered (see EN 50177).
All unauthorized conversions and modifications to the electrostatic spray-
ing equipment are forbidden for safety reasons.
No safety devices should be dismantled or put out of operation.
Mandatory operational and workplace notices from the operating compa-
ny must be written in a comprehensible manner in the language of
equipment operators and posted in a suitable place.

6 • General safety regulations OptiFlex 2 V
Powder lying on the floor around the powder spraying equipment is a po-
tentially dangerous source of slipping. Booths may be entered only in the
places suitable for it.
Static charges
Static charges can have the following consequences: Charges to people,
electric shocks, sparking. Proper grounding must be in place to prevent
objects from becoming charged.
Grounding
All electrically conductive parts found in the workplace of 5 meters around
each booth opening, and particularly the objects to be coated, have to be
grounded. The grounding resistance of each object must amount to max-
imally 1 MOhm. This resistance must be checked/tested regularly when
starting work.
The condition of the work piece attachments, as well as the hangers,
must guarantee that the work pieces remain grounded. The appropriate
measuring devices must be kept ready in the workplace, in order to check
the grounding.
The floor of the coating area must conduct electricity (normal concrete is
generally conductive).
The supplied grounding cable (green/yellow) must be connected to the
grounding screw of the fresh powder system. The grounding cable must
have a good metallic connection with the coating booth, the recovery unit
and the conveyor chain, respectively with the suspension arrangement of
the objects.
Smoking and igniting fire are forbidden in the entire vicinity of the system!
No work that could potentially produce sparks is allowed!

ing regulations

OptiFlex 2 V General safety regulations • 7
As a general rule for all powder spraying installations, persons with
pacemakers should never enter high voltage areas or areas with electro-
magnetic fields. Persons with pacemakers should not enter areas with
powder spraying installations!
Photographing with flashlight can lead to unnecessary releases and/or
disconnections by safety devices.
Disconnect the plugs before the machines are opened for maintenance or
repair.
The plug connections between the powder spraying equipment and the
mains should only be removed when the power supply is switched off.
As far as it is necessary, the operating firm must ensure that the operating
personnel wear protective clothing (e.g. facemasks).
A dust mask corresponding to filter class FFP2 or N95 at minimum must
be worn during any cleaning work.
The operating personnel must wear electrically conductive, steel-toe
footwear (e.g. leather soles).
The operating personnel should hold the gun with bare hands. If gloves
are worn, these must also conduct electricity.
These general safety regulations must
be read and understood in all cases
prior to start-up!
The stay for persons
with cardiac pace-
makers is forbidden

carried out according to local regulations.
- It must be ensured, that all components are earthed accord-
ing to the local regulations before start-up.
OptiFlex 2 V Fresh powder system
The OptiFlex 2 V fresh powder system is a constituent part of the equip-
ment and is therefore integrated in the system's safety concept.
If it is to be used in a manner outside the scope of the safety concept,
then corresponding measures must be taken.
