Specifically, the following ECN examples identified design changes and errors which were not adequately evaluated or identified to Elgar's customers (90-01-02):

(1)ECN1680,IntegratedCircuit(IC)Socketproblemsregarding seismic fragility-(previously identified as Unresolved Item L

88-01-07 in NRC Inspection Report 99908871/88-01 and discussed in Section D.6 of this report).

(2)ECH2413,Improperinstallationofsemiconductordevices.

(3) ECH.2572, Interference between a terminal > block and front panel of 7.5 kilo-volt ampere (KVA) inverter regarding a lamp board l

assembly.

(4) ECN 3751, Numerous design changes to rectify problems on the driver logic board.

(5) ECH 4532, Capacitor design change to the static switch drive board.

(6) ECN 5322, Potential for electrical shorting of terminal block leads on 7.5 KVA inverter lamp board assemblies.

(7) ECN 5570, Fuse blowing problem corrected on the DC to DC L

converter board.

(8) ECH 7095, Incorrect termination of certain CMOS type IC logic gate input pins.
