Standardised Eurovent conditions: water heat exchanger entering/leaving water temperature 12°C/7°C, outside air temperature 35°C
** Power input of the compressor(s) + fan(s) at maximum unit operating conditions saturated suction temperature 10°C, saturated condensing temperature 65°C at
400 V nominal voltage (Values given on the unit name plate).
*** Maximum unit operating current at maximum unit power input and 380 V.
**** Maximum unit operating current at maximum unit power input and 400 V (Values given on the unit name plate).
†
Maximum instantaneous starting current at operating limit values (maximum operating current of the smallest compressor(s) + fan c locked rotor current of
the largest compressor).
Fan motor electrical data: current draw used in the tables above – units at Eurovent conditions and 50°C ambient air temperature around the motor at 400 V: 3.8 A,
start-up current 20 A, power input 1.75 kW. These values are indicated on the motor name plate.

Type of system earthing
IT system:
The short circuit current stability values given above for the TN system are also valid for IT for units 30RQ 302 to 522.
For units 30RQ 262 modifications are required.
