    GENERAL MAINTENANCE CHAPTER 5: MAINTENANCE General maintenance The 350 requires minimal maintenance. As a microprocessor-based relay, its characteristics do not change over time. The expected service life of a 350 is 20 years when the environment and electrical conditions are within stated specifications. While the 350 performs continual self-tests, it is recommended that maintenance be scheduled with other system maintenance.
