• The site of installation must be dry and free of dust, if possible. Air cir-
culation must not be obstructed (see chapter 3.1 "Assembly of the high
voltage generator”, page 11).
• To make sure that no high voltage is applied at the bars when the
machine is not running, the supply voltage to the generator should be
enabled via a machine contact which disables the high voltage when
the machine is at rest (see chapter 3.7 "Connecting the supply voltage”,
page 16).
• When routing the high voltage cable observe all notes in chapter 3.3
"Installation of the high voltage cables”, page 12.
• 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 units (see chapter 3.7 "Connect-
ing the supply voltage”, page 16).
• (see chapter 3.4 "Charging bars suitable for connection”, page 13).
• The high voltage cable must be pushed up to the stop (90 mm) into the
cable inlet! The connecting area of the high voltage cable must be kept
clean (see chapter 3.5 "Connecting the high voltage cable to the high
voltage generator and to the distribution box”, page 14).
• To avoid damaging the generator, make sure that the signals are con-
nected correctly (see chapter 3.8 "Analog interface”, page 18).
• Fusing protection for the fault alarm contact must be provided by the
customer (see chapter 3.8 "Analog interface”, page 18).
• Shielded cables must be used to wire the analog interface and for all
interface cables; the shield must make contact on both sides (see chap-
ter 3.8 "Analog interface”, page 18, chapter 3.9 "Laying the cable shield
of the interface cable”, page 21, chapter A.1 "Assembly instructions
Plug connectors Analog interface”, page 45).
• In the variant with connecting terminals, the cable shield of the interface
cable must be routed via the EMC cable gland to ground potential (see
chapter 3.9 "
Laying the cable shield of the interface cable”, page 21).
• If <YES> has been selected for automatic runup, high voltage is
available immediately after the supply voltage to the generator is
switched on (see chapter 4.6 "
Specific operating parameters for the
high voltage output”, page 29).
• Make sure that the units are clean at all times.
Dirt results in malfunctions and in premature wear of the units.
• The IP54 protection class applies only if the lid of the enclosure is
closed and the cable entries are covered.
