• Any work involving the units must be carried out by qualified electri-
cians (see chapter 5 "Maintenance”, page 16, chapter 6 "Trouble-
shooting”, page 17).
• Before starting the unit make sure that the appliance is permanently
grounded via the grounding terminal (6, Fig. 1). The ground cable
should have a minimum cross section of 1.5 mm
2
(see chapter 3.2
"Ground connection”, page 11).
• 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”,
page 12).
• In applications involving moving bars (e.g. film draw strips), 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 voltage cable”, page 12).
• Both the lengths of the high voltage cable and of the active bars are
limited, observe maximum lengths (see chapter 3.5 "Maximum active
bar length and length of the high voltage cable”, page 13).
• 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 supply voltage”, page 13).
• 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 chapter 4.1
"Startup”, page 15).
• The power supply must be checked regularly to ensure its proper func-
tioning. The connections of the high voltage cables must be free of dirt
and other foreign matter (see chapter 5.1 "Power supply”, page 16).
• Make sure that the bars are clean at all times. Dirt results in malfunc-
tions and in premature wear of the units.
