Weight shown is a guideline only. .
**
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.

*
Maximum instantaneous start-up current at operating limit values (maximum operating current of the smallest compressor(s) + fan current + 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).
†
Maximum unit operating current at maximum unit power input and 360 V.
4.5 - Short-circuit stability current (TN system*) - standard unit (with main disconnect switch)
BW10
Value without upstream protection
Short-term current at 1 s - Icw - kA rms
Admissible peak current - Ipk - kA pk
Value with upstream protection (circuit breaker)
Conditional short-circuit current Icc - kA rms
Schneider circuit breaker - Compact series
Reference number**
*
Earthing system type
**
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.
