Maintaining the DataSite Configured Panel 31

Battery intervals may vary with the addition of external loads to the
system or rapid changes in ambient temperature. Periodic maintenance
and measurement of battery life should be done to ensure system
reliability.

10. Check all fuses. If replacing fuses, install the same type and rated fuse

that was originally furnished with the DataSite configured panel.

11. Remove accumulated dust and dirt from structure and individual units

by vacuuming. Do not use compressed air, as it may contain moisture
and blow debris within the enclosure.

12. Refer to individual user policies, NFPA 70B, Recommended Practice for

Electrical Equipment Maintenance for Servicing Guidelines.

This table was developed with the assumption that batteries are maintained
properly without additional loads connected to system. Replacement schedules
for additional loads may vary depending on size of load connected. Also, this
table is based on temperature only as the load on the battery will only affect
the battery life if the load is greater than or equal to 1 W continuous.
