Before commencing with wiring, ensure that all power to the SECTOR II
is OFF.
Lightning Protection
The
S-SERIES
electronic controller utilises the same proven surge protection philosophy that is
used in all products from Centurion Systems (Pty) Ltd. While this does not guarantee that the
unit will not be damaged in the event of a lightning strike or power surge, it greatly reduces the
likelihood of such damage occurring. The earth return for the surge protection is provided via the
mains power supply earth.
In order to ensure that the surge protection is effective, it is essential
that the unit is properly earthed.
