5.2 Standardization information
Series BUM 62, 63, 64 are built-in units in the sense of provisional standard EN 50178/VDE 0160/11.94,
Section 5.2.6 and DIN VDE 0558 Part 1/07.87, Section 5.4.3.2.1. They are intended for installation in
commercially available control cabinets whose degrees of protection meet the minimum requirements of
provisional standard EN 50178/VDE 0160/11.94, Section 5.2.4 (IP 2x, possibly IP4x according to EN
60529/5.1).
Plastic covers on the equipment provide additional protection against accidental contact in the case of
casual use of control elements located close to the equipment (DIN VDE 0106 Part 100, Accident Pre-
vention Regulation VBG4 "Electrical Systems and Equipment").
If you intend to set up the equipment in closed electrical workshops according to provisional standard
EN 50178/VDE 0160/11.94, Section 5.2.7 and DIN VDE 0558 Part 1/07.87, Section 5.4.3.2.2, you must
implement additional measures to ensure compliance with the requirements of provisional standard EN
50178/VDE 0160/11.94, Section 5.2.4.
These power converters are intended for permanent mains connection to conventional TN and TT sys-
tems according to DIN VDE 0100 Part 410/11.83 with a diametric voltage of up to 3x500Veff ("and not
more than 5000 rms symmetrical amperes", if UL508C has to be observed
(Nov 27, 1996, Tab. 44.1)
Connecting to a system with an insulated neutral point (IT system) is only possible under special circum-
stances. If necessary, enquire at the factory.
During operation, the principles on which the power converter and the motor work lead to leakage cur-
rents to earth occurring that may be dissipated via the specified protective earths and may result in a
current-operated e.l.c.b. on the input side blowing prematurely. In the case of a short-circuit to frame or
to ground, a direct proportion may arise in the leakage current that makes triggering a higher-level cur-
rent-operated e.l.c.b. either more difficult or totally impossible. This means that connecting the power
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).
With regard to climatic conditions, the equipment conforms to category 3K3 for sheltered locations ac-
cording to provisional standard EN 50178/VDE 0160/11.94, Section 6.1, Table 7, Line 3 or Table 1 of
EN 60721-3-1,2,3,4 respectively, taking into account Remarks 1 and 3 of provisional standard EN
50178/VDE 0160/11.94, Section 6.1. The actual operating temperature range is higher and is in the
range 0 .. +55°C. The information in Table 7 (lines 5 and 6) of provisional standard EN 50178/VDE 0160/
11.94, Section 6.1 also applies to storage and transportation.
The storage and transportation temperature of the equipment varies from this information in as much as
it may be between -30 ... +70°C (refer to Technical Data).
The units are in protection class IP 20 according to EN 60529 (DIN VDE 0470-1)
The units are equipment in protection class I corresponding to IEC 536/3 and DIN VDE 0106 Part 1 (pro-
visional standard EN 50178/VDE 0160/11.94, Section 5.2.9).
Equipment of protection class I is equipment whose protection against dangerous shock currents is not
limited to basic insulation but which also has additional safety devices. This additional protection is pro-
vided by connecting the housing and other parts to the protective earth such that if the basic insulation
fails no voltage can remain. With these power converters, the entire insulation is carried out according
to provisional standard EN 50178/VDE 0160/11.94, Section 5.2.9.1, at least to basic insulation standard.
This also applies to the insulation between the individual circuits.
The power converters' control terminals are safely isolated from the mains and are designed for connec-
tion of SELV and PELV circuits.
At measurement of the creepage distances and clearances, the following criteria were taken into ac-
count:
- Soiling grade 2 according to provisional standard EN 50178/VDE 0160/11.94, Section 5.2.15.2, Table
