Overview
PM230 Power Modules – 0.37 kW to 75 kW (0.5 hp to 100 hp),
IP20 degree of protection
PM230 Power Modules, degree of protection IP20, standard variant,
frame sizes FSA to FSF (with Control Unit and Operator Panel)
PM230 Power Modules, degree of protection IP20, push-through variant,
frame sizes FSA to FSC (with Control Unit and operator panel)
PM230 Power Modules are designed for applications involving
pumps, fans and compressors with a square characteristic.
They do not have an integrated braking chopper (single-
quadrant applications).
The PM230 Power Module only generates low line harmonics
and apparent power losses. In addition to the energy-related
advantages, environmental stressing is also reduced.
•
Line harmonics are reduced significantly.
- The limit values of EN 61000-3-2, EN 61000-3-4 and
IEC 61000-3-12 are maintained for R

three phase devices is identical to R
SC
according to
IEC 60146-1-1.
- Additional components such as line reactors are not
required and it is not permissible to use them. As a
consequence, low envelope dimensions are obtained
for space-saving designs.
•
The active power component is very high, i.e. the devices
consume less current from the supply for the same drive
power. As a consequence, smaller supply cables can be
used.
Frame sizes FSA to FSF of the PM230 Power Module in degree
of protection IP20 standard variant are available with integrated
line filter class A for installations according to Category C2 and
in accordance with EN 61800-3 or without an integrated line
filter.
Frame sizes FSA to FSC of the PM230 Power Module in degree
of protection IP20 push-through variant are available with inte-
grated line filter class A for installations according to Category
C2 and in accordance with EN 618003, or without an integrated
line filter.
In order to maintain EMC categories C2 (line filter A) or C1
table 14 (line filter B, conducted), the permissible shielded
cable lengths between the inverter and motor are limited
(for maximum permissible cable lengths,
see Integration
).
The permissible cable lengths between inverter and motor are
limited (for max. permissible cable lengths,
see Integration
).
Longer cables can be used if output reactors are connected
for PM230
(see section Load-side power components)
.
The line system configurations that are supported are sym-
metrical systems with grounded neutral point.
PM230 Power Modules do not support Control Units with Safety
Integrated. Safety functions can be implemented by means of
external switching devices.
PM230 Power Modules with integrated filter class A or class B,
防护等级IP55 / UL类型12日0.37 kW到90 kW (0.5 hp
to 125 hp) are integral components of the SINAMICS G120P for
pumps, fans and compressors.
Detailed information can be
found in Catalog D 35.
Note:
Shield plates and shield connection kits are available. These can
be used in the wiring installation for the Control Units and Power
Modules to ensure that it complies with EMC guidelines.
For further information, see Shield connection kits and Shield
plates for Control Units and Power Modules in section Supple-
mentary system components.
