2.3 Work and operational safety
Warning!

Carefully observe the following notes and the complete chapter 2 "Safety”,
page 6 !
• Before carrying out repairs, cleaning or maintenance work involving the
power supplies and the discharging bars, switch off the power supply
and disconnect the mains power supply (see
chapter 5 "Maintenance”,
page 13 , chapter 6 "Trouble-shooting”, page 14 ).
• Before carrying out any work involving the units, the machine which has
the units fitted must not be in operation (see chapter 5 "Maintenance”,
page 13 , chapter 5 "Maintenance”, page 13 ).
• Any work involving the units must be carried out by qualified electricians
(see chapter 5 "Maintenance”, page 13 , chapter 6 "Trouble-shooting”,
page 14 ).
• Before starting the unit make sure that the appliance is permanently
grounded via the ground connection (5, Fig. 1). The ground cable
should have a minimum cross section of 1.5 mm
2
(see chapter 3.2
"Ground connection”, page 9 ).
• Disconnect and/or connect the bars and the cables only when the
power supply is swiched off (see chapter 3.4 "Connecting the high vol-
W
age cable”, page 10 ).
• Terminals at the housing that are not used must be closed with blanking
plugs (see chapter 3.4 "Connecting the high voltage cable”, page 10 ).
• Check the units, the electrical wiring and the high voltage cables at

regular intervals and before the start-up for any damage. Any damaged
components must be repaired professionally or replaced before con-

tinuing to operate the units.
• If the housing cover is removed, contact protection is no longer effec-
tive. Always disconnect 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.
• Both the lengths of the high voltage cable and of the active bars are li-
P
ited, observe maximum lengths
• Please note the maximum total lengths of the bars and the high voltage
cables in chapter 3.5. (see chapter 3.6 "Connecting the supply voltage”,
page 11 ).
• Keep the bars clean at all times. Dirt results in malfunctions and in pre-
mature wear of the units.
• 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 12 ).
