10.2 Checking and Exchanging Various
Components
NOTICE
Qualified Person Only!
10.2.1 Fuse Check
Check the fuse when the device fails to work with significant error (E9XX).
Do not perform Fuse Check when the device is working.
Check the fuse after turning off the DC disconnect switch and the AC circuit breaker.
Measure both ends of the Inverter PBA (SJ92-01425A) F3, BDC PBA (SJ92-01426A) JF1 to
check the resistance value.
If the resistance value is open state (Mega ohms or Infinite value), perform PBA exchange.
10.2.2 Input / Output Terminal Check
Check the input / output terminal when the device fails to work with significant errors (E9XX).
Check the input / output terminal after turning off the AC circuit breaker and DC disconnect
switch.
Do not perform the check when the device is working.
Measure the input / output terminal with a multi-meter.
PV1 input (SJ92-01426A): CN13, CN14
PV2 input (SJ92-01427A): CN13, CN14
Battery input: CN17, CN27
AC output: CN1, CN4
If the resistance value is in a short state (close to 0), perform PBA exchange.
10.2.3 DC Link Check
Check the DC Link when the device fails to work with E102.
Check the DC Link after turning off the AC circuit breaker and DC disconnect switch.
Measure both ends of the DC link PBA (SJ92-01428A) CN1, CN2 with a multi-meter to check
the resistance value.
