▶ Do not remove or connect electric circular plug until the power
supply has been disconnected.
Risk of explosion when opening the device.
▶ Open device only when no explosive atmosphere is present.
Risk of explosion caused by electrostatic discharge.
In the event of a sudden discharge from electrostatically
charged devices or individuals, there is a risk of explosion in
the potentially explosive atmosphere.
▶ Protect device from large charge-generating processes.
▶ Ground housing before start-up.
▶ Take suitable measures to ensure that no electrostatic dis-
charges can build up in the potentially explosive atmosphere.
▶ Clean the device surface by gently wiping it with a damp or
anti-static cloth only.
