Procedures
3Trip Unit Operation Verification diagnostic
Tools: Trip unit test kit
- Connect a test kit to the trip unit test plug receptacle.
- Perform verification tests per instructions shipped with the test kit to verify trip unit functions.
Battery replacement / battery rack installation maintenance
- Isolate DC supply before working on battery connections.
- Install battery rack with hold-down, floor standing.
- Install battery with minimum 2200 amps capacity at -18 °C to 0 °C.
- Verify 24 volt negative ground connection.
Trip Unit Switch Adjustment operation
⚠ Wait a minimum of 15 minutes after circuit breaker trips before resetting to allow thermal imaging to reset completely to zero.
Tools: Wire seal MICROTUSEAL
- Open switch cover.
- Adjust the appropriate switches to desired values.
- Replace switch cover.
- Use wire seal MICROTUSEAL, if necessary, to provide tamper evidence.
