12. MAINTENANCE & TESTING
Before removing any unit from service
ensure that power to the device is
isolated. Replacement of any Movtec
units should only be undertaken in
accordance with all relevant Electricity
and Safety Standards by suitably
qualified personnel.
Movtecs should be inspected periodically, and
also following any periods of lightning or
transient activity. Check the status indicators
and replace if in the “Alarm” condition as
detailed in Section 10 -STATUS INDICATION.
For high transient exposure sites or those of a
critical operational nature, it is recommended
that the alarm outputs be monitored to
provide an additional warning of reduced
capacity (refer Section 10).
Movtecs are designed for optimum
performance under severe transient activity.
To provide this performance, electronic
components in the Movtec are encased in a
patented proprietary, shock and thermal
absorbant compound. Units cannot be
serviced, they must be replaced.
Do not attempt to open or tamper with the
units in any way as this may compromise
performance and will void warranty.
Do not “Megger” or perform other types of
electrical tests that apply voltages greater
than the nominal operating voltage of the
Movtec. The Movtec will attempt to limit these
voltages thereby affecting the test result.
Where these tests must be performed, remove
the Movtec from circuit first.
