Safety information for cleaning and
maintenance
DANGER!
Electricity throughout entire device!
Personnel danger due to electric shock or electric burns.
–
Before beginning work, disconnect all of the power
connections from mains voltage.
–
Secure all of the disconnected connections against
accidental reactivation.
–
Check that the device is disconnected from mains volt-
age.
–
All of the work and electrical connections must comply
with the national regulations of the country in which the
device is being operated (e.g. the VDE regulations in
Germany) and must be undertaken by appropriately
trained specialists.
If work is to be performed on the devices, they must be deenergized. That
means that all live cables must be switched off.
Switching off the device alone is insufficient, as certain points may remain
energized. Therefore, switch off fuses before performing any work and – if
possible – remove them.
Accidental reactivation can result in serious accidents. Immediately after
deenergizing, secure all switches or fuses used for deenergizing against
being switched on again.
–
Lock the fuse box with a padlock.
In case of circuit breakers which cannot be unscrewed, a strip of adhesive
tape may be applied over the actuation lever with the wording 'Do not switch,
danger!' (1 + 2).
A prohibition sign with the text:
'Work in progress!'
'Place: ..............................'
'Sign may only be removed by: ............'
must always be securely mounted immediately.
