112 Appendix 3 Wiring Diagram
Configuration explanation:
1. AC input: three schemes optional. The 3P+N+PE/380V is one option. See AC input distribution schemes for other options.
2. Rectifiers: 2 ~ 5 pieces optional.
4. BLVD and LLVD: the DC output routes and battery routes are protected by MCBs. The contactors are normally-closed type. The LLVD contactor KM2 is optional.
5. DC distribution: DU is optional. The sum dimension of the load MCBs should be smaller than 410mm. The MFU can be configured with load MCBs. The sum dimension of the load MCBs should be smaller than 190mm.
7. Load alarm signal connection of the monitoring backboard: the first 8 load alarm signal cables connect to the first 8 load alarm terminals of the monitoring backboard. The rest 2 signal cables connect to the 9th and 10th terminal of the monitoring
backboard if the DU is not configured, or connect to the signal transfer board of the DU if DU is configured.
9. This diagram describes the flexible configuration system. The actual wiring, devices and components configured are determined by the configuration document and described in corresponding design document.
3. The number of the battery MCBs is determinded by requirements. 2 ~ 4 routes optional.
6. If the monitoring module is M501D, refer to the wiring of the monitoring backboard for M501D. If the monitoring module is M800D, refer to the wiring of the monitoring backboard for M800D.
8. There are 22 load alarm signal cables in the DU, all connected to the monitoring backboard via the two signal transfer boards in the DU.

1. Before wiring, attach specified labels to the corresponding positions according to the design document.
Technical requirement:
2. Peel the heat shrinkable tube before wiring if the cable terminal is wrapped with it. If the cable needs no connection,
