Rated insulation voltage of the mains input circuits (TN- and TT- networks) is 849 V
according to EN 50178/VDE 0160, section 3.64.
Series BUM64S/A/F units are conditional short-circuit-proof in the sense of EN 50178/
VDE 0160, sect. 6.3.4.
During operation, the principles on which the power converter and the motor work lead to
leakage currents to earth occurring. These are to be conducted by use of the appropriate
protective conductors which may lead to a premature release of a series fault current cir-
cuit breaker.
.
Protection against direct contact with the units is achieved by installing them in commer-
cially available switching cabinets. Their degree of protection must meet at least the min-
imum requirements of EN 50178/VDE 0160, section 5.2.4 and EN 60204-1, chapter 12.4.
Plastic covers on the equipment provide additional protection against accidental contact
when commissioning or in case of casual use of control elements located close to the
equipment. For the power connection additional measures must be taken according to
IEC 60536-2, chapter 5.1.1, German accident prevention directive “Electrical plants and
working funds“ VBG4.
Essential for personal protection are the safety measures and security regulations ac-
cording to DIN/VDE.

WARNING
The following
may occur
,
if you do not observe this warning information:
m
serious personal injury
m
death
The hazard is:
Electricity.
When there is body contact or earth leakage a direct current com-
ponent in the fault current can be generated. This may hinder or keep a fault current circuit
breaker from working properly.
Connecting the single power unit to mains input only by use of a fault current circuit breaker
is forbidden (EN 50178/VDE 0160, sections 5.2.11 and 5.3.2.1).
WARNING
The following
may occur
,
if you do not observe this warning information:
m
serious personal injury
m
death
The hazard is:
Electricity.
Missing protective conductor connections at the unit or at the motor can lead to personal dam-
age.
Connect the protective conductors.
Discharging time of voltage conducting parts is > 1 min.
Before working at voltage conducting parts check with adequate test equipment that the parts
do no longer conduct voltage. Touch parts only after you have assured that they are voltage
free and after unit and motor have been secured against reactivation.
