Conduct in the event of a hazardous situation
The behavior in the event of a hazardous situation is dependent on
assembly at the operator.
Basically:
- Shut down the power supply.
- Close the pipe work and release the pressure.
- Discharge the residual energy. (Use the earthing rod).

Responsibility of the operator
The atomizer is part of an electrostatic spray system of a stationary
spray unit for coating with non-flammable liquid coating materials,
which do not generate an explosive atmosphere within the spray
range. When designing, planning, constructing, erecting, setting up
and operating such a spray unit, EN 50348 must be noted and
adhered to.
The following points are particularly important:
- Integration in the on-site fire protection concept
- Integration in the on-site security concept:
- Emergency stop
- Safe switching off the high voltage
- Discharge of residual energies.
- Handling paint, detergents and cleaning agents
- Constant pressure - pressure monitoring.
If the atomizer is operated as a category “2G” device, it must be
ensured that during operation, the high voltage is switched off before
the first discharge. The shutdown function must be adjusted and
tested prior to commissioning. Furthermore, the shutdown function
must be tested every 12 months.
The procedure is described in the standard EN 50176.
In the chapter “Optional accessories” of this manual you will find a
case that contains the necessary equipment for testing the shutdown.
Fire protection
The painting booth must have a fire protection system. In the event of
fire, the fire protection system shall be activated automatically and
without delay. High voltage supply and supply of paint and detergent
and compressed air must be turned off automatically.
