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 length diagram up to 2 amps for drives with a current draw < 2.5 A
Nominal drive current in amps

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 amp nominal curent draw)
Note: Permissible current supply of the TRZ Plus Comfort has to be considered, see technical data.
A = cable cross-section
I = sum of the rated drive current draws
*L = simple line length
73 = factor, made up from 2.5 V max. permissible voltage drop and
electrical conductivity of copper
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!
Examples of cable types and fittings that can be used
Cable system, consisting of load support system and cables with appropriate fire protection tested wall
plugs and screws. Cable system in accordance with DIN 4102-12 Safety cable + layout system.
