SIMOVERT MV Commissioning Instructions
2.1.2 Application and operation
SIMOVERT MV drive converters are designed in accordance with EN 50081-2 and
EN 50082-2 for use in industrial environments. They may not be operated on public
low-voltage networks. They must always be operated with the doors closed.

It is not permissible to use radio equipment (walkie-talkies) with a radiating power
> 2 W close to the drive converter.
For radio equipment with lower outputs, a clearance of > 1 m must be maintained.

The motor feeder cables must be screened. The screen must be grounded at both
ends. In addition, a potential bonding conductor (cross-section > 50 mm
2
) must be
routed between the motor and drive converter (connected to the grounding plate).

All of the components of the plant/system, which are connected using signal
cables, must also be connected using potential bonding conductors (exception:
components with fiber-optic cable connections), e.g.:

Drive converter B

Each drive converter cabinet has a potential bonding- and grounding rail to make it
easier to connect the potential bonding conductors. All internal and external
components must be connected to this potential bonding rail.
All of the cabinets which are involved with networked drives, must be connected
using a potential bonding conductor (min. 16 mm
2
) (the PE connection on the
customer side is not sufficient).
The screens of incoming and outgoing cables must be connected directly to the
screen rail (serrated rail). In this case, it must be ensured that the connection is
established through the largest surface area to establish a good electrical
connection.
