Ordering examples
Example 1
Task:
A converter cabinet unit is required to control the fan speed for
a 380 kW fan drive connected to an existing 400 V MCC outgo-
ing feeder. The rated speed of the fan is 975 rpm. Due to the pre-
vailing ambient conditions, the converter must be mounted on a
100 mm cabinet base and have IP54 degree of protection. The
installation altitude is < 1000 m above sea level, the ambient
temperature is 45° C.
Solution:
Because an MCC outgoing feeder already exists, line connec-
tion components, such as main switch, line contactor and line
fuses, can be omitted and the space-saving version C can be
selected. If we take into account the derating factors for the IP54
degree of protection and the increased ambient temperature, a
450 kW, 400 V converter cabinet unit with options
M06
(cabinet base 100 mm) and
M54
(IP54 degree of protection) must be selected for this con-
stellation.
The ordering data is as follows:
6SL3710-1GE38-4CA3-Z
+M06 +M54
Example 2
Task:
A 280 kW pump to control pressure compensation is to be sup-
plied via a converter for a completely new district heating pump-
ing station. A 690 V supply is available. The installation altitude
is 350 m above sea level and the ambient temperature is 40° C.
The rated speed of the pump is 740 rpm. The pump unit and mo-
tor are located in an unmanned substation, so the winding tem-
perature of the motor must be monitored by Pt100 thermistors
and evaluated by the converter. The color of the converter cabi-
net units is to be RAL 3002.
Solution:
A converter cabinet unit with 315 kW, 690 V in the version A with
the following options should be selected:
L26
(main switch including fuses),
L13
(line contactor),
L86
(Pt100 evaluation unit) and
Y09
(special cabinet paint finish).
The ordering data is as follows:
