General safety regulations
This chapter sets out the fundamental safety regulations that must be fol-
lowed by the user and third parties using the OptiCenter OC04.
These safety regulations must be read and understood before the Opti-
Center OC04 is put into operation.
Safety symbols (pictograms)
The following warnings with their meanings can be found in the Gema
Switzerland operating instructions. The general safety precautions must
also be followed as well as the regulations in the operating instructions.

ment
INFORMATION!
Useful tips and other information
Intended use
−The OptiCenter OC04 is built to the latest specification and con-
forms to the recognized technical safety regulations and is de-
signed for the normal application of powder coating.
−Any other use is considered non-compliant. The manufacturer is
not responsible for any incorrect use and the risks associated
with such actions are assumed by the user alone. If the OptiCen-
ter OC04 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 instruc-
tions specified by the manufacturer is also part of conformity of
use. The OptiCenter OC04 should only be used, maintained and

started up by trained personnel, who are informed about and are
familiar with the possible hazards involved.
−Start-up (i.e. the execution of a particular operation) is forbidden
until it has been established that the OptiCenter OC04 has been
set up and wired according to the guidelines for machinery
(2006/42 EG). EN 60204-1 (machine safety) must also be ob-
served.
−Unauthorized modifications to the OptiCenter OC04 exempt the
manufacturer from any liability from resulting damage.
−The relevant accident prevention regulations, as well as other
generally recognized safety regulations, occupational health and
structural regulations are to be observed.
−Furthermore, the country-specific safety regulations also must be
observed.

Product specific safety information
General information
The OptiCenter OC04 is a constituent part of the system and is thus inte-
grated into the safety system of the plant.
If it is to be used in a manner outside the scope of the safety concept,
then corresponding measures must be taken.
NOTE:
For further information, see the more detailed Gema safety regula-
tions!

Installation
The services and facilities to be provided by the customer should be in-
stalled according to local regulations.
Grounding
Check the grounding of the booth and the powder management center
before every start-up. The grounding connection is customer specific and
is fitted on the booth base, on the cyclone and on the powder manage-
ment center. Also make sure that the workpieces, and all other systems
are properly grounded.
Operating the equipment
In order to be able to operate the equipment safely, it is necessary to be
familiar with the safety regulations, the operational characteristics and
functioning of the various plant units.
For this purpose, read the safety notes, this operating manual and the
operating instructions of the plant control unit, before starting up the plant.
In addition, all further equipment-specific operating instructions, e.g. the
OptiFlex and all additional components should also be read.
To obtain practice in operating the plant, it is absolutely essential to start
the operation according to the operating instructions. Also, later on, they
serve as a useful aid on possible malfunctions or uncertainty and will
make many enquiries unnecessary. For this reason, the operating manual
must always be available at the equipment.
Should difficulties arise, however, your Gema service center is always
ready to assist.
Inspection
Before switching on the booth, check the following points (where applica-
ble):
−No foreign material in the central suction unit in the booth and in
the powder suction
−Sieve machine is connected to the cyclone separator, the clamp
is tightly locked
−Pneumatic conduction and powder hose are connected to the
dense phase conveyor

Repairs
Repairs must be carried out by trained personnel only. Unauthorized con-
versions and modifications can lead to injuries and damage to the equip-
ment. The Gema Switzerland GmbH guarantee would no longer be valid.
NOTE:
We point out that the customer himself is responsible for the safe
operation of the equipment! Gema Switzerland GmbH is in no way
responsible for any resulting damage.
By carrying out repairs, the powder management center must be discon-
nected from the mains, according to the local safety regulations!
NOTE:
Only original Gema spare parts should be used! The use of spare
parts from other manufacturers will invalidate the Gema guarantee
conditions!
