Dahle Quality Manager ABB Power T&D Company Inc. Relay Division 4300 Coral Ridge Drive Coral Springs, FL 33065 (305) 752-6700 This letter is a notification of a potential defect on the Class 1E type CVE-1 relay style numbers 1326D67A01 and 1326D67A02. This defect consists of an incorrectly rated telephone relay used as V1 and V2. The Class 1E type CVE-1 relays are equipped with two 110 volts rated telephone relays. The typical operating voltage in the field exceeds the telephone relays (V1 and V2) rating; therefore, the telephone relays may overheat and fail. To correct this, the design has been changed to a 120 volts rated telephone relay. A copy of this notification is being sent to all customers who our records indicate have purchased these type of relays. If you have any questions or require any additional information regarding this announcement, please do not hesitate to contact the Quality Manager at the Relay Division. Cheryl A. Dahle Jose R.
