&all legal instructions regarding the
prevention of accidents,
&all legal instructions regarding
environmental protection,
&the Code of Practice of relevant
trade associations.
&all current safety regulations as
defined by DIN, EN, VDE and all
locally applicable standards
Working on the system
&Isolate the system from the power
supply and check that it is no longer
'live', e.g. by removing a separate
fuse or by means of a main isolator.
&Danger
Contact with 'live' compo-
nents can lead to severe inju-
ries. Some components on
the PCBs will remain 'live'
even after the power supply
has been switched OFF.
&Prior to removing equipment
covers wait at least 4 min. to
allow the voltage to dissi-
pate.
&Safeguard the system against
unauthorised reconnection.
!Please note
