6.1.2.1 Connection of the 24Vac power
supply line
Before the installation, make sure the
specifications of the power supply system
match the ones required by the device.
Make sure the power supply system and the
connection cables are properly sized.
The earth cable must be approximately
10mm (0.4in) longer than the other two
cables to prevent it from accidentally
coming off if it is stretched.
The power supply cable should also be
covered by the silicone sheath (01) supplied
for this purpose, and fastened with the
corresponding tie (02).
Cut the cables to the correct length and make the
connections. Connect the power supply to the
terminal.
