CTC EcoPart i425-i435 Pro 

General Information

5.3.2 Shielded communication

When there is a series connection, the loop which connects position Sc of 
the control terminal block and PE on the mains terminal block must also be 
removed and replaced by the shielding, which is then connected up to the 
next heat pump (control terminal block position Sc). This must be done on all 
heat pumps except the last cooling module in the series connection.
