WARNING
Spark formation
The impact of corroded steel parts on the aluminium hous-
ing at high speed can cause spark formation and thus lead
to an explosion.
➢ Choose the installation position carefully, so that there
are no external impacts.
➢ Fasten the NEA/NEG securely.
➢ Check the fastening regularly (generally monthly).
WARNING
Hazard of electrostatic discharge
When cleaning the NEA/NEG with a dry cloth there is a risk
of electrostatic discharge. A electrostatic discharge can lead
to an explosion due to ignition of an explosive atmosphere.
➢ Only clean the NEA/NEG with a wet cloth.
➢ Remove dust deposits regularly.
➢ The following warning label is located
on the NEA/NEG and must be observed:
WARNING
Static electricity
The discharge of charged, isolated conductive parts can
cause ignitable sparks.
➢ Connect the earthing screw of the NEA/NEG to the po-
tential equalisation of the higher-level machine.
➢ Include all components in the potential equalisation of
the machine.
