30 Maintaining the DataSite Configured Panel
4. Check for the proper function and freedom of movement (no sticking
or binding) for the disconnect switch (800H), and defeater mechanisms.
Replace broken, deformed, malfunctioning or badly worn parts or
assemblies.
5. Inspect current carrying parts such as fuse clips, knife blades of
disconnects and line and load terminals of devices for discoloration,
corrosion or other signs of wear or possible failure.
6. Check locking or interlocking devices for proper working condition.
Adjust, repair or replace any device if necessary.
7. Check for loose wire connections on power and control circuit
terminals. Loose connections can cause overheating, hot spots or arcing
faults that could lead to equipment malfunction or failure. Replace any
damaged parts or wiring.
8. Check relay coils for evidence of overheating, such as cracking, melting
or burning of insulation. If there is evidence of overheating, the coil
must be replaced. When replacing a coil, check and correct the
over-voltage or under-voltage conditions that may have caused the coil
failure. Be sure to clean any residue of melted coil insulation from other
parts of the device and replace as necessary.
9. Check battery terminals for excessive corrosion. If corrosion is present
clean or replace batteries or terminals as needed.
Batteries should be replaced at recommended intervals. The table,
Recommended Battery Replacement Schedule on page 31 , shows the
recommended intervals between battery replacements based on ambient
temperatures.
WARNING
Follow NFPA 70E, 2004 safety guidelines when working on
energized equipment. To prevent injury or death to personnel
lubricating disconnect switch contacts, make sure DataSite
configured panel power source(s) is disconnected and the
respective disconnect(s) is locked in the OFF/O position. To
prevent personal injury or damage to equipment, make sure
that the unit handle operator is in the OFF/O position before
working on the unit.
ATTENTION
Failure to replace batteries may lead to a loss in backup power
resulting in the loss of function of the DataSite configured
panel.
