BE1-49 Maintenance 6-1
SECTION 6 • MAINTENANCE
GENERAL
Basler relays are static devices which require no preventive maintenance other than a periodic operational
check. The operational test procedure of Section 5 provides an adequate check to verify proper operation of
the relay.
If the relay fails to function properly, contact the Technical Support Services Department of Basler Electric for
a return authorization number before returning the relay for service.
STORAGE
This protective relay contains aluminum electrolytic capacitors which generally have a life expectancy in
excess of 10 years at storage temperatures less than 40°C. Typically, the life expectancy of an electrolytic
capacitor is cut in half for every 10°C rise in temperature. Storage life can be extended if, at one year intervals,
power is applied to the relay for a period of 30 minutes.
