Overview
PM240-2 Power Modules – 0.55 kW to 132 kW
(0.75 hp to 200 hp), IP20 degree of protection
PM240-2 Power Modules, frame sizes FSA to FSF
(with Control Unit and Operator Panel)
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
Integrated Drive
(see section Control Units)
.
The PM240-2 Power Modules frame sizes FSA to FSC are avail-
able 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 (for max. permissible cable lengths,
see Integration
).
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.
