Reconnection Options
In the case of storage tanks with optional heating times, reconnection of the heating rods is to be carried out in
accordance with the circuit diagram pasted to the device. Switching installed at the factory is in line with the
6-hour heating time in ~ 230 V connection voltage. The polyphase circuits from 100 litres upwards, 3 ~
400 V and 3 N ~ 400 V, are also to be connected in accordance with the following table.
Reconnectable heating times and outputs at associated protection currents 16A.
Details in bold indicate switching undertaken at the factory (6 hours ~230 V)
