2.9.4 De-icing battery pack power supply (optional)
VEX520 à VEX550 unit: We recommend a 20A circuit breaker with a sensitivity differential of
300mA and 4mm2 section cable for the general power supply.
VEX560 à VEX580 unit: We recommend a 40A circuit breaker with a sensitivity differential of
300mA and 6mm2 section cable for the general power supply.
Caution:
three-phase power supply for all sizes.
