41
The cross-section of the power cable must be chosen according
to the length of the cable and the type of installation, based on
the maximum current input of the air-conditioner and so as to
prevent excessive voltage drops (the power supply voltage must
be between ± 10% of the rated value).
The following table shows the minimum recommended cross-sec-
tions for the power cables.
- A backup fuse should be fitted upstream of the power
line for short-circuit current up to 10 kA.

B = cooling only
R = cooling only + STD hearters
H = cooling only + humidifier
