Notes on safety
Connection work is only admissible when no voltage is present. Observe the 5
safety rules (see chapter 2.5 Working on the machine).
Make note of the following points:
•
The drive controller housing must be closed before you turn on the power
supply voltage.
•
When the power supply voltage is turned on, hazardous voltages may be
present on the connection terminals and the cables connected to them.
•
The device is not reliably free of voltage simply because all the displays are
blank!
The following actions are prohibited while the power supply voltage is turned
on:
•
Opening the housing
•
Connecting or disconnecting connection clamps
•
Connecting or disconnecting connection wiring
•
Removing or installing accessories.
Protect the device against falling parts (bits or strands of wire, pieces of metal,
etc.) during installation or other work in the control cabinet. Parts with
conductive properties may result in a short circuit or device failure within the
drive controller.
Use only copper conductors. For the corresponding lead cross-sections
consult standards DIN VDE 0298-4 or DIN EN 60204-1 (appendices D, G) as
well as the relevant terminal specifications in this documentation.
The protection class is protective grounding. Because of this, operation is only
admissible if the protective ground wire is connected according to
requirements.
The essential protective ground connections are identified by "PE" or the
international symbol for grounding (IEC 60417, symbol 5019
).
The drive controllers are not designed for use in a public low frequency network
that supplies residential areas. High-frequency interference can be expected if
the drive controllers are used in a network of this type.
Drive controllers are products subject to sales restrictions in accordance with
IEC 61800-3.
The drive controllers are not designed for use in a public low frequency network
that supplies residential areas.
In a residential environment this product may cause high-frequency
interference. If this occurs the user may be asked to take suitable measures.

Wiring
Observe the regulations applicable for your machine or system when installing
the electrical equipment, e.g. DIN IEC 60364 or DIN EN 50110.
7.2.2
Protective measures
The drive controllers are only suitable for operation on TN networks and only
for use in supply current networks that are able to provide a maximally
symmetrical nominal short circuit current at 480 volts according to the following
table.
