ELECTROCUTION hazard!
There is a risk of fatal electric shocks when
performing work on electrical devices. With
all maintenance or repair work, the pump
must be disconnected from the mains and
secured against being switched on again
without permission. Damage to the power
supply cable may only be rectified by a quali-
fied electrician.
UNAUTHORISED work could result in fatal
injuries!
Maintenance and repair work that impairs the
safety of Ex protection must only be carried
out by the manufacturer or authorised service
workshops.
