Notes
Allowed voltage tolerance ± 10%. Voltage unbalance between phases must be within ± 3%.
Maximum starting current: starting current of biggest comp fans current
Nominal current in cooling mode is referred to the following conditions: SS T 7°C; ambient 35°C;
comp fans current.
Maximum running current is based on max compressor absorbed current in its envelope and max fans
absorbed current
Maximum unit current for wires sizing is based on minimum allowed voltage
Maximum current for wires sizing: (compressors full load fans current) x 1.1.

Notes
Allowed voltage tolerance ± 10%. Voltage unbalance between phases must be within ± 3%.
Maximum starting current: starting current of biggest compressor + current of the compressor at 75%
maximum load + fans current
Nominal current in cooling mode is referred to the following conditions: evaporator 12°C/7°C; ambient
35°C; compr fans current.
Maximum running current is based on max compressor absorbed current in its envelope and max fans
absorbed current
Maximum unit current for wires sizing is based on minimum allowed voltage
Maximum current for wires sizing: (compressors full load fans current) x 1,1.
