Components and manufacturer documentation
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 →
