• If electrically conductive substrates or substrates coated with conduc-
tive material (e.g. metal foil or metal composites) are used, the mains
supply must be interrupted (see
chapter 4.2 "Operating mode with con-
).
• Before carrying out any work involving the units, the machine which has
the units fitted must not be in operation (see
chapter 6 "Trouble-shooting”, page 15
• Any work involving the units must be carried out by qualified electrici-
ans (see
chapter 5 "Maintenance”, page 14
).
• Before starting the unit make sure that the appliance is permanently
grounded via the grounding terminal (5, Fig. 1). The ground cable
should have a minimum cross section of 1.5 mm

• Check the power supplies and the discharging bars at regular intervals
for any damage to the electrical wiring and the high voltage cables. Any
damaged components must be repaired or replaced before continuing
to operate the units.
• If the housing cover is removed and the supply voltage is switched on
at the same time, contact protection is no longer effective. Always dis-
connect the power before opening the power supply units.
• The protection class IP54 only applies if the housing cover is closed
and the cable connections are shrouded.
• Connect/disconnect the discharging bars only if the power supply unit is
switched off (see
chapter 3.4 "Connecting the high voltage cable”,
).
• In applications involving moving bars, the high voltage cable must be
attached such that there is no cable movement near the connection
zone of the power supply unit (see
chapter 3.4 "Connecting the high
).
• Both the lengths of the high voltage cable and of the active bars are
limited, observe maximum lengths (see
bar length and length of the high voltage cable”, page 11
• To ensure that no voltage is supplied to the bars when the material web
is at rest, enabling the supply voltage to the power supply via machine
contact is recommended. If the material web is at rest, or if the machine
is not in operation, no high voltage is supplied to the bars in this case
(see
chapter 3.6 "Connecting the supply voltage”, page 12
).
• Before starting up the power supply the user must make sure that the
power supply and the bars have been installed and assembled cor-
rectly. The supply voltage can then be switched on (see
