MG.30.A7.02 - VLT
®
is a registered Danfoss trademark
Derating for installing long motor cables or
larger cable cross-section
The VLT
®
3002-3052 is tested with 300 m
unscreened cable and 150 m screened
cable (for types 3002-3004 this only
applies to f
SWITCH
≤
4.5 kHz. At f
SWITCH
> 4.5
kHz, max. 40 m).
The VLT
®
3000 Series is designed to run
with a motor cable of a rated cross-section. If
a cable with a larger cross-section is to be
used it is recommended to reduce the out-
put current by 5% for each step the
cable cross-section is increased.
(Higher cable cross-section gives
increased capacity to earth and thereby in-
creased earth current).
