Testing after repair shall be carried out in accordance with EU directives.
WARNING
Risk of explosion due to alteration of the ignition gap geometry
Changing ignition gap geometries (gap dimensions) as part of repair work according to the
minimum specifications of IEC / EN 60079–1 is not permissible.
This can result in death, serious injury or material damage.
•
Obtain the gap dimensions of the electrical machine from the manufacturer for the repair
or restoration of ignition gap geometries.
9.1.9.7
Maintaining the external fan (forced ventilation)
WARNING
Rotating or live parts
Live electrical parts are dangerous. Contact with them can cause death, serious injury or
material damage.
Before performing any maintenance work on the external fan, disconnect it from the mains,
particularly before opening the terminal box. Make sure that the device cannot be switched
back on.
Servicing the external fan
The external fan is essentially maintenance-free. However, dirt and dust deposits on the
impeller and the motor, particularly in the gap between the impeller and the inlet nozzle can
impair its function.
●
Remove the dirt and dust deposits regularly; the intervals depend on how dirty the
surrounding area is.
●
Make sure that the impeller is evenly cleaned, as irregular deposits can lead to an
imbalance.
The full flowrate is only achieved if the inward flow of air to the impeller is unrestricted.
Servicing the external fan motor
Please observe all specifications and intervals in the operating instructions for the external
fan motor. If a SIMOTICS XP 1MB1.5/1MB5.5 low-voltage motor is used as an external fan
motor, these operating instructions also apply for the external fan motor.
