Safety instructions for cleaning and
maintenance
DANGER – HIGH VOLTAGE!
You can be killed or injured by an electric shock!
During maintenance work there is a risk of touching live
parts and receiving a fatal electric shock.
–
Disconnect device from power supply before opening.
–
Do not reach behind covers and do not open the device
with the device switched on.
–
Refit any safety devices (e.g. switches) after the work
has been completed.
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 be-
ing 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!'.
A prohibition sign with the text:
'Work in progress!'
'Place: ..............................'
'Sign may only be removed by: ............'
must always be securely mounted immediately.
It is imperative that you, the owner and/or operator, check all components for
any signs of wear which may occur through normal use.
–
Observe the cleaning and maintenance schedule specified in the tables
in Chapter 7.4 and 7.6.
–
Only replace UV low-pressure lamps with the original type or compatible
lamps.
