5.3 - Electrical protections
In the factory, a switching device can be integrated as an
option to the Powerdrive MD2SL .
The optional power switch integrated to the drive
doesn’t isolate the input busbars of the drive.
During the installation and maintenance operation
ensure that the supply line is open.
References and size of the options below, mounted in
a Powerdrive MD2SL , are detailed in the Leroy-Somer
Configurator : http://configurateurls.leroy-somer.com
5.3.1 - aR semi-conductor fuses
The aR semiconductor fuses limit the consequences of
an incident related to a short-circuit in the drive. They don’t
provide protection to the drive power line and must always be
associated with a protective device against overload located
upstream the line.
aR semiconductor fuses kits (optional Fu aR) are available for
Powerdrive MD2SL .
5.3.2 - Line switch
A 3-pole switch is available for the Powerdrive MD2SL.
This option is used to isolate the motor from the AC
supply during maintenance operations.
• Fully visible break with padlockable handle on the front
of the drive cabinet (can be turned manually, padlock not
supplied)
• Conforming to standard IEC/EN 60947-3
The QS3P switch must always be included in aR semi-
conductor fuse kits, in accordance with the table in section
3.1.5.
The QS3P switch is necessarily associated with
semiconductor aR fuses in compliance with table § 3.1.

5.3.3 - Emergency stop
• MD2-AU1: SIL1/PLb protection device
The MD2-AU1 protection device consists of an emergency
stop wired on the STO inputs and mounted on the front.
• SIL3/PLe protection device
The Powerdrive MD2SL can be made compatible with
SIL3/PLe by incorporating a safety relay for double channel
locking.
Contact LEROY-SOMER.
5.4 - Heater kit
To prevent condensation in the Powerdrive MD2SL a self-
limited temperature heater is available as an option.
The intaller must provide ~230V single phase protection (fuse
rating indicated below) and ensure its control (the module
must be turned off when the drive is in operation).
5.5 - RFI filters
The use of RFI filters contributes to a reduction in the
emission levels of radio-frequency signals. They allow the
compliance of the Powerdrive MD2SL components with the
variable speed standard EN61800-3.
Depending on the drive and the application, install the RFI filter
recommended (available as option) between the mains and the
drive input.
CAUTION:
The specific design of these filters makes it possible
to connect to IT power supplies. The installer should,
however, ensure that insulation supervision systems
dedicated to these installations are suitable for
monitoring electrical equipment that may contain
electronic variable speed drives.
