ronmental pollution.
Note
Details identified by the word "Note" con-
tain additional information.
Target group
These instructions are exclusively
designed for qualified personnel.
■ Work on electrical equipment must
only be carried out by a qualified elec-

associations
■ All current safety regulations as
defined by DIN, EN, DVGW, VDE and
all locally applicable standards
aÖNORM, EN and ÖVE
cSEV, SUVA, SVTI and SWKI
Working on the system
■ Isolate the system from the power sup-
ply and check that it is no longer 'live',
e.g. by removing the separate fuse or
by means of a main isolator.
Note
In addition to the control circuit, there
may be several power circuits.
■ Safeguard the system against unau-
thorised reconnection.
!Please note
