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 be able to be switched on only if 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 ROMER spare parts will guarantee that the explosion
protection will be preserved. If damages occur by using spare parts
from other manufacturers, 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.
The operating and job instructions has to be written in an understandable
form and in the language of the persons employed, and has to be an-
nounced in a suitable place in the working area.
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.
