9. Maintenance
Although very little maintenance is required with Alpha systems, routine checks and adjustments are recommended
to ensure optimum system performance. Qualified service personnel should do the repairs.
The following table lists a few maintenance procedures for this system. These procedures should be performed at
least once a year.
To order more breakers refer to the options listed in the specifications. Always replace circuit breakers with the same
type and rating.
Consult factory for all replacement parts.
Use extreme care when working inside the unit while the system is energized. Do not
make contact with live components or parts.
Circuit cards, including RAM chips, can be damaged by static electricity. Always wear a
grounded wrist strap when handling or installing circuit cards.
Ensure redundant modules or batteries are used to eliminate the threat of service inter-
