For all indoor connections (between the units) and outdoor connections (power supply
and unit), low-voltage electrical installations must be observed. The main power supply
and control cables must be made of copper and/or aluminium, with PVC-type insulation
for a minimum temperature of 70
o
C.
The maximum distance between the two voltage points is 50m. For values above 50m, it
is recommended to verify the specification of new gauges and must comply with local
codes.
For the cable gauge values of the main power supply, presented in the tables, the use of
copper and/or aluminium cables was considered, with insulation of the PVC 70
o
C type
and conductors loaded according to the local codes.
For the control power supply cables between the units, the use of a minimum
1.5mm
2
(70
o
C) gauge is recommended.
