[A] Delivery condition
[B] If 1-phase connection is needed, a cross connector/jumper must
be installed between (L1, L2 and L3).
[C] If you remove the cross connector/jumper between (N and 1N) at
connection 400 V 3 N~. Output of electric heater, 3 steps:
K1 = 1500 W
K2 = 3000 W
K1 + K2 = 4500 W
K1 + K2 + K3 = 9000 W
[1] 400 V ~3 N power supply
[2] 230 V ~1 N power supply for single phase heat pump
(compressor)
[3] 230 V ~1 N power supply for heating cable (accessory)
[4] 230 V ~1 N power supply EMS module (accessory)
[5] 230 V~1 N power supply
Electric heater, 4 steps at 230 V 1 N~ and 400 V
3N~
K1 = 2000 W
K2 = 4000 W
K1 + K2 = 6000 W
K1 + K2 + K3 = 9000 W
When the compressor is operating, only stages 2000 W, 4000 W or
6000 W are available. The electric heater can only be turned on with
