Electrical diagrams

Electrical drawings · R1.2

Current reference issue: R1.2 · 14 sheets. View the PDF below or download the editable PowerPoint. R1.2 supersedes D12/D13 as the electrical reference, but it does not by itself constitute independently signed as-built or commissioning documentation. Known omission: the voltmeter supply branches and missing external fuse protection for PV1/PV2 are not shown. Do not regard these drawings as an approved as-built metering/protection record; see PV-FUSE-01 before live use. For connector name cross-references and documented open technical checks, use the electrical overview and technical review.

The PDF includes a clickable table of contents: use the Contents icon in the PDF viewer to expand six sections and jump to any of the 14 named drawing sheets.

Additional circuit overviews

Each circuit is shown separately so the control supply, heating command and external DC power cannot be mistaken for the same electrical path. Device references correspond to the numbered connection diagrams below.

The external heater DC supply is independent of the 24 V controller supply. Finder 62.31 terminal 14 (−) and Crydom load terminal −2 are on the switched positive heater path, not on the DC negative return.

Connection diagrams · all 70 routes

Each line maps one FROM → VIA → TO route. A shared distribution-net label is an electrical junction, not an extra conductor. Select a title to jump to the matching table.

Connection groups are based on the R1.2 electrical schedule. The two Murata input-voltmeter connections are not included in the 70 numbered routes. See the voltmeter reference for their actual arrangement and outstanding protection requirement.
