Overview
PM230 Power Modules – 0.37 kW to 90 kW (0.5 to 125 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

according to
EN 61000-3-2, EN 61000-3-12 and EN 61000-3-4 and for
three-phase devices is identical to RSC 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 conse-
quence, low envelope dimensions are obtained for space-
saving designs.
•
The active power component is very high, i.e. the devices con-
sume 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 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 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 to max. 25 m
(82 ft).
The permissible cable lengths between inverter and motor are
limited. Longer cables can be used if output reactors are con-
nected for PM230
(see section "Load-side power components")
.
The line system configurations that are supported are symmetri-
cal systems with grounded neutral point.
The PM230 Power Modules don't support Control Units with
Safety Integrated. External switchgears can implement safety
functions.
PM230 Power Modules with integrated filter class A or class B,
degree of protection IP55/UL Type 12, 0.37 kW to 90 kW (0.5 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
Supplementary system components.
