Electrical cables should be drawn according to regulations by qualified per-
sonnel. The control system and its cables should be installed in compliance
with current national legislation and the requirements of local authorities.
Maximum cable length/prescribed cross-sectional size of
cables
The maximum allowed cable lengths between control unit and motor and the
prescribed cross sectional sizes of the cables are given in the table below. The
cable must be protected according to National/European Standards.
Calculation of max. cable length:
56 x A/l
A
is cable cross-section and
I
is max motor current in total.
Allowed maximum voltage drop in the cable:
2 V
Operation current:
The total of all motor currents.
