Electrical connections
Procedure
•
Switch off the power supply before making any connections .
•
Use a thermal grease in thermistor pocket after installing electric connections .

Connections to be made in the electrical box of DHW tank
1 . Connect the booster heater power supply and thermal protection cable .
2 . Make sure to ensure strain relief of the cable .
Connections to be made in the electrical box of indoor units
3 . Plug the thermistor cable connector in the connector CNS042 on the pcb .
4 . Connect the booster heater power supply and thermal protection cable(field supply) to terminal TB-A1 and earth on the
terminal block .
5 . Connector the loose ends of the TB-A1 on the terminal block and the connector CNS042 on the PCB .
6 . Plug the thermistor cable connector in the socket X9A on the PCB .
7 . Connect the booster heater power supply and thermal protection cable (field supply) to terminal 7, 8, 21, 22 and earth on
the terminal block .
8 . Connect the booster heater power supply cable to the circuit breaker and earthing screw .
9 . Fix the cables to the cable tie mountings with cable ties to ensure strain relief .
