Isolate Mains Power to appliance as per TOPs P4
Observation:
Are the external controls potential free or are they switching mains voltage?
If they are potential (voltage) free then they should be connected to the terminal block on the back of the control box (blue and yellow leads).
If they are mains voltage switching then they should be connected to the green terminal block on the 230 volt controls interface PCB.
Note:
If mains voltage switching controls are present select the
"Mains voltage switching controls present" option below.
If potential free (no voltage) switching controls are present select the "Potential (voltage) switching free controls fitted" option below.
If they are potential (voltage) free then they should be connected to the terminal block on the back of the control box (blue and yellow leads).
If they are mains voltage switching then they should be connected to the green terminal block on the 230 volt controls interface PCB.
Note:
If mains voltage switching controls are present select the
"Mains voltage switching controls present" option below.
If potential free (no voltage) switching controls are present select the "Potential (voltage) switching free controls fitted" option below.
Isolate as per TOPs P4
and refit as necessary
