5.1 Technical Design Considerations

WARNING
FUNCTIONAL-SAFETY COMPLIANT USE
®
The VLT Plus Panel is a product in accordance with the
Low Voltage Directive 2006/95/EG, but does not provide
safety-related control functionality in accordance with
Machine Safety Directive 2006/42/EG. CE declaration is
therefore related to EMC (2004/108/EG) and LV Directive.
Failure to take the necessary safety-related control
measures can result in death or serious injury.
•
The panel operator has to ensure the proper
use of the product, even when Safe Torque Off
(STO) functionality is used, for example for
ATEX-conform motor thermal protection. In this
case, the safety function is part of the approved
motor thermal protection, using the function as
appropriate energy cut-off.
•
Any other use of the safety functions is in sole
responsibility of the end user, including certifi-
cation, documentation, and so on.
•
Customized variants can differ and are not
subject to the panel configurator product
description.
NOTICE
The notification of maximum possible cross-section and
number of wires is shown in drawings for each main
component, where mains and motor cables can be
directly connected. The drawings are provided with the
panel.

For VLT
(normal overload) values are used for the
design. Due to the 80% design rule of EN
61439-2, design is adjusted for the HO
(high overload) use. Details are provided
per power rating in the relevant
documents.
RDF RDF is specified to 1 for all power circuitry as
only 1 frequency converter is foreseen per panel/
infeed.
Cables/wires Cables/wires used according to DIN standards,
cross-section in mm
can be used. Always consider local standards
must always be taken into considerations.
Energy Energy cabling is done directly to the relevant
cabling terminals of switchgear, frequency converter, or
filter.
Cable entry Bottom cable entry.
Wiring color According to DIN EN 60204-1.
