OPERATION:
After applying power to the SPD, verify that the protection monitoring circuits are functioning
correctly. If all status alarms indicate “normal”, the SPD has been successfully installed and is
operational.
1. LINE STATUS INDICATOR LEDs
The green line status LED’s provide visual indication of SPD health status. As long as the SPD
is connected to the electrical system supply voltage and the SPD suppression circuitry is
functional, the line status indicators will be illuminated green. There is one green indicator
per each protected phase on TR5 65KA - 100KA RATED Models. TR5 25KA - 50KA RATED
Models have 1 green status indicator to monitor the health of the entire SPD.
2. REMOTE ALARM CONTACTS
Remote Alarm Contacts are available to remotely monitor the health status of the SPD. An
alarm condition will result in a status change of the contacts. These contacts do not affect
the performance of the SPD and are not required to be connected for the SPD to function as
intended.
MAINTENANCE:
GE does not provide a specific schedule for preventative maintenance as conditions will vary
based on location and the environmental factors presented at each installation site. However,
periodic inspections should be scheduled to verify that the SPD does not indicate a failure mode.
Inspections should also be made to check the integrity of the electrical supply connections to the
SPD to ensure continued reliable performance.
WARNING
UPON ENERGIZATION OF THE SPD, IF ANY OF THE LAMPS OR ALARMS
INDICATES AN ABNORMAL CONDITION, POWER SHOULD PROMPTLY BE
DISCONNECTED FROM THE SPD. THE ELECTRICAL SYSTEM SHOULD BE
INSPECTED AND THE PRE-INSTALLATION REQUIREMENTS SHOULD BE
VALIDATED. DO NOT ATTEMPT TO LEAVE POWER APPLIED TO THE SPD, OR RE-
ENERGIZE THE SPD IN THE EVENT OF AN ALARM CONDITION. PLEASE
CONTACT YOUR LOCAL GE REPRESENTATIVE FOR FURTHER ASSISTANCE.
