If 230 V power supply is used, change the motor connection
from star to delta and change the setting of the thermal cut-
out as well.

Electrical connections (Fig. 16)
Set up by the installer
Use flexible cables according to regulation EN 60 335-1:
if in PVC boot, use at least H05 VV-F
if in rubber boot, use at least H05 RR-F.
All the cables to be connected to the burner terminal strip 8)(Fig.
16) must be routed through the fairleads.
The fairleads and precut holes can be used in various ways. One
