Short-circuit stability and protection See table below "Short-circuit stability current"
* Maximum instantaneous start-up current at operating limit values (maximum operating current of the smallest compressor(s) + fan c locked rotor current of the largest
compressor).
** Power input, compressors and fans, at the unit operating limits (saturated suction temperature 10°C, saturated condensing temperature 65°C) and nominal voltage of 400 V
(data given on the unit nameplate).
*** Standardised Eurovent conditions: evaporator entering/leaving water temperature 12°C/7°C, outside air temperature 35°C.
**** Maximum unit operating current at maximum unit power input and 400 V (values given on the unit nameplate).

** If another current limitation protection system is used, its time-current and thermal constraint (I²t) trip characteristics must be at least equivalent to those of the recommended
Schneider circuit breaker. Contact your nearest Danfoss office.
The short-circuit stability current values above are in accordance with the TN system.

** The length and width dimensions are the same as for the standard unit.
*** When delivered, the standard pre-inflation of the tanks is not necessary the optimal value for the system. To permit changing the water volume, change the inflation pressure to
a pressure that is close to the static head of the system. Fill the system with water (purging the air) to a pressure value that is 10 to 20 kPa higher than the pressure in the tank.
