Cable Length Diagram
To determine the necessary cable cross-sections as a
function of the line length and the sum of the rated currents
of the drives.

Cable Cross-Section Determination
Notes re-cable cross-section determination and cabling layout
Simplified formulae for cable cross-section determination (for drives up to 2.5
A nominal current draw)
Note:
Permissible current supply of the TRZ Plus has to be considered,
see technical data.
A = cable cross-section
I = sum of the rated drive current draws

Notes re-selection of cables
For the motor supply cables of SHE drives 3 or 5 (duplicated
layout) individual cores are required.
Two cores (4 cores) are for the motor voltage, the 3rd or 5th
core respectively is required for monitoring the cabling.
The selection and layout of the cables is to be performed
according to (model) utility facilities guidelines (MLAR). Here
particular attention is to be paid to E30 or E90 functionality
retention!
