2.12 Putting into service
To put the equipment into service, perform the following sequence of operations at each end of the feeder.
Insert the supply links and fuses.
Make a final inspection to ensure that the equipment is ready for automatic tripping. In particular check that the
flag-indicator is re-set, that the metering test-link of each relay is firmly inserted and that all connections are tight.
Finally, insert the tripping links, the protection is then ready for service.
2.13 Operation
No action is required in the event of a fault on the primary circuit external to the protective zone. On clearance of
an internal fault the relay should automatically reset, but the flag-indicator would require to be reset by hand. It
should only be reset after the fault has been logged.

2.14 Maintenance
The maintenance test required will largely depend upon experience and site conditions; but it is recommended
that the inspection and tests under "Check of Connections", "Secondary Wiring and Insulation Resistance Tests"
and "Overall Fault-Setting Tests", be performed every five years. "Pilot Tests" should be repeated at this time but
may be repeated more frequently based on experience of the condition and environment in which the connection
is installed.
