• 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 Filter PBA F101, F102, and F401 check the resistance value.
• If the resistance value is open state (Mega ohms or Infinite value), perform PBA exchange.
• Voltage rating : 600 Vac/Vdc
• Current rating : 30 A

10.2.2 Input / Output Terminal Check

• Check the input / output terminal when the device fails to work with significant errors.
• 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 : CN104, CN105
- PV2 input : CN107, CN106
- Battery input : CN401
- Load output : CN603
- AC output : CN1 (Sub Filter Board)
• If the resistance value is in a short state (close to 0), perform PBA exchange.

10.2.3 DC Link Check
