6.3 Applicable standards
The power units of the series BUM 62 T are built-in devices according to EN 50178 / VDE 0160 / 11.94,
Section 5.2.6 and DIN VDE 0558 Part 1/07.87, Section 5.4.3.2.1.
Sheets of plastic covering the power connections, additionally prevent accidental contact during
commissioning and casual use of control elements located close to the equipment (DIN VDE 0106 part
100, Accident Prevention Regulation VBG4 "Electrical Systems and Equipment).
If the units are to be installed in closed electrical premises according to EN 50178/VDE 0160/11.94,
Section 5.2.7 and DIN VDE 0558 Part 1/07.87, Section 5.4.3.2.2, the user must ensure by additional
measures that the requirements according to EN 50178/VDE 0160/11.94, Section 5.2.4 are met.
Mains connection
The power unit is provided for the fixed mains connection to TN and TT mains according to DIN VDE
0100, Part 410/11.83 with a linked mains voltage of up to 3 x 460 V + 15%.
The power unit can be connected to IT mains using an isolating transformer with the neutral grounded
at the secondary side.
During operation, the principles on which the converter and motor work, lead to leakage currents to earth
which are dissipated via specified protective earth connections and which may result in a current-
operated e.l.c.b. on the input side blowing prematurely. A DC component in the fault current may occur
in the event of a short-circuit to frame or earth fault which makes a triggering of the higher-level current-
operated e.l.c.b. more difficult or even impossible. Universal-current sensitive current-operated e.l.c.b.
and current-operated e.l.c.b. for AC and pulsating AC fault currents with a rated fault current of 300 mA
are suitable.
The connection of the converter to the mains using only the current-operated e.l.c.b. is
prohibited (preliminary standard EN 50178 / VDE 0160 /11.94, sections 5.2.11 and 5.3.2.1)
Climatic conditions / Temperature
Concerning climatic conditions, the units of the climatic category 3K3 for sheltered locations acc. to EN
50178/VDE 0160/11.94, Section 6.1, Table 7, Line 3 or acc. to Table 1 of
EN 60721-3-1,2,3,4 under consideration of Note 1 and 3 of EN 50178/ VDE 0160/11.94, Section 6.1.
The actual operating temperature range is between 0 to +55 °C. For storage and transport, the
specifications of Table 7 (lines 5 and 6) of EN 50178/VDE 0160/11.94, Section 6.1 apply.
Unlike these specifications, the storage and transport temperature of the units may adopt values
between -30 and +70 °C (see technical data).
Type of protection
The type of protection of the units is IP 20 acc. to EN 60529 (DIN VDE 0470-1).
The power units are equipment of protection class I according to IEC 536/3 and DIN VDE 0106 Part 1
(EN 50178/VDE 0160/11.94, Section 5.2.9).
