(1) Values obtained at unit continuous maximum operating conditions (data given on the unit nameplate)
(2) Standardised EUROVENT conditions, water-cooled exchanger water inlet/outlet = 12°C/7°C, condenser entering/leaving water temperature = 30°C/35°C
(3) Start-up current is limited by the soft-start controller included in the compressor.
(a) When the machines are equipped with two power supplies, circuit 1 supplies the refrigerant circuit A and circuit 2 supplies the refrigerant circuit B
Note: Options 84 and 84R are not included in these values.
4.3 - Short-circuit stability current for all units
Short-circuit stability current for all units using the TN system (earthing system type): 50 kA (conditional system short-circuit current
Icc/Icf at the unit connection point as rms value).
All units are equipped with circuit breakers located in the control box immediately downstream from the unit connection point.
