Overview
SINAMICS G120 standard inverters
0.37 kW to 250 kW (0.5 hp to 400 hp)
Power Modules
PM240-2 Power Modules – 0.55 kW to 15 kW
(0.75 hp to 20 hp), degree of protection IP20
PM240-2 Power Modules, degree of protection IP20, standard variant,
frame sizes FSA to FSC
PM240-2 Power Modules, degree of protection IP20, push-through
variant, frame sizes FSA to FSC (with Control Unit and Operator Panel)
The new PM240-2 Power Modules are based on a new hardware
platform. This permits an increase in power density as well as
the application of innovative cooling concepts (push-through
technology) with especially high requirements in terms of control
cabinet cooling.
Furthermore, the PM240-2 Power Module is also suitable for use
in safety-oriented applications. In conjunction with a fail-safe
Control Unit, the drive can be transformed into a Safety Inte-
grated Drive
(see section "Control Units")
.
The PM240-2 Power Modules frame sizes FSA to FSC are
available both with and without an integrated line filter class A of
compact design for 200 V and 400 V line voltages.
The PM240-2 Power Modules with integrated line filter class A
are suitable for connection to TN supply systems. Power
Modules without integrated line filter can be connected to
grounded TN/TT systems and non-grounded IT systems.
The permissible cable lengths between inverter and motor
are limited. Longer cables can be used if output reactors are
connected
(see section "Load-side power components")
.
Push-through variant
The push-through variant allows the cooling fins of the
Power Module to be pushed through the rear panel of the control
cabinet. Push-through variants should be used in applications in
which the amount of waste heat generated inside the control
cabinet itself must be minimized.
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.
