Typical configuration
Where proper use is observed, the limit values for the interference voltage
at the power supply connection and for the interference emission from de
vices belonging to Group 1 Class A (industrial sector) will not be exceeded
by the following typical configurations.
The measurement record will confirm that the limit values are not ex
ceeded.
1
.
Measurement of the interference voltage on the mains supply
cable (150 kHz up to 30 MHz)
h
Measurement configuration acc. to CISPR with an artificial mains
network 3 x 400 V/16 A or 3 x 400 V/32 A (50 A)
h
Limit values for ISM devices belonging to Class A, Group 1 acc. to
EN 55011 (CISPR 11), industrial sector
h
Measurement record on request
h
Measures for installation in domestic, business, commerical and
small enterprise sectors on request.
2.
Measurement of interference emission (30 MHz to 1000 MHz)
h
Measurement of the interference emission at an alternative mea
suring point 10 m away.
Due to the short measuring distance (10 m instead of 30 m), the
limit values are raised by 10 dB
µ
V, see also EN 500812 and
CISPR/1073/CD April 95.
h
Measurement configuration acc. to CISPR, 10 m measuring dis
tance on a ground plane. The ground plane consists of a copper
foil screen layed out on the ground.
The drive modules and the mains filter are mounted on a galva
nized steel plate on a 0.8 m high wooden table. The motors are on
a Europallet under the wooden table.
The distance betweeen the power line and motor line is > 0.5 m.
Mains power is supplied from a switch cabinet 10 m away, the 24
V supply from a power supply module 10 m away.
h
Limit values for ISM devices belonging class A,
Group 1 + 10 dB
µ
V in acc. with EN 55011 (CISPR 11),
industrial sector.
h
Measurement record on request.

Measures for installation in domestic, business, commerical and
small enterprise sectors on request.
