3.11.7 Connecting an extra error signal ('Alarm OUT' )
Alarm OUT is a potential free terminal that is switched when an error is
detected. This can be used to signal errors, for example with a lamp. A 230 V
circuit can be directly powered. Other voltages require a relay prescribed by
the manufacturer.
1. Connect the phase cables (X1 and X2) to terminals 13 and 14 according to
the table (3.11.2"Pre paration"). If required, connect earth ( ) to terminal 15.
2. Fit the cable in the strain relief.
3. If you have no more connections to make:
- Fit the cap on the electrical terminal block.
- Fit the plastic covers onto the appliance.
3.11.8 Connecting communication cable to solar heating system
You must connect a communication cable between the controllers of the
appliance and the solar heating system.
1. Connect the cables (X5 and X6) to terminals 1 and 2 as indicated in the
table(3 .11.2"Preparation").
2. Fit the cable in the strain relief.
- If you do not need to make any more connections:
- Fit the cap on the terminal block.
- Fit the covers onto the appliance.
