separate protection segments. Each Status
Indicator is illuminated when power is
available and when full surge capacity is
available by that segment. The Surge
Suppressor should be replaced if either
Status Indicator fails to illuminate. Note: The
Status Indicators will not operate (regardless
of surge capacity) if power is not available.
8S units
These units are identified by four Status
Indicators which operate similar to above. The
Surge Suppressor should be replaced if any
two or more Status Indicators fail to
illuminate.
13. MAINTENANCE & TESTING
Before removing any unit from service
ensure that power to the device is
isolated. Replacement of any Surge
Suppressor should only be undertaken in
accordance with all relevant Electricity
and Safety Standards by suitably
qualified personnel.
TDS-DINLINE units should be inspected
periodically, and also following any periods of
lightning or transient activity. Check the
status indicators and replace if recommended
in Section 12 -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 14 - ALARM RELAY-
TDS-AR).
