7. CABLING
Connect power leads of the control gear and frequency converter of the fan
drive according to the Electric diagram.
The wire cross-sections have been selected for long term current capacity for
cables arranged in the air (supported on brackets, cable racks, in perforated
trays) with spacing from the wall of min. 0.3 cable diameter, insulated with PVC,
for 3-conductors loaded.
Due to the protection selectivity, length, cable placement method and
short-circuit currents, revise the feeders’ cross-sections in the table below.
