The electronic controller utilises the same proven surge protection philosophy that is
used in all our products. 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 and/or earth spike located next to the operator.
While care has been taken in the design of the D5 SMART to prevent unauthorised
removal (theft) of the unit, an optional steel theft-deterrent cage is also available for
added peace of mind.
INTRODUCTION
SECTION 1
1.2. Lightning Protection
1.3. Theft Protection
In order to ensure that the surge protection is effective, it is essential
that the unit is properly earthed.
If a theft-deterrent cage is required, be sure to leave enough clearance from
pillars, etc. (Section 7.1.2. - "Minimum Clearances").
