Component identification

The reference list covers the incoming mains equipment, controllers, relays, SSRs, buttons, lamps, protection, all specified distribution blocks and panel connectors. The register defines the reference design; inspect actual markings when replacing an installed part.

The two-channel electrical arrangement includes two Murata DMR20 DC meters, four red and four black Electro PJP 4 mm panel sockets, and two Type K panel sockets. Each Murata meter contains an internal self-resetting fuse, but neither PV1 nor PV2 has external input-wire fusing fitted. Murata specifies 0.25 A / 300 V time-delay protection for TB1 (+/−) supply wiring. External fuses/fuseholders are not included as fitted components; selection, installation and testing remain an open engineering action. PV-FUSE-01 maintenance notice →
