6.4.2. External auxiliary 3-phase power supply input
An external power supply is required for system start-up. This is not needed once the system is running.
The requirements are summarized in Table 6.1. The connection terminals are located in the APS
enclosure on fuse holders F6-1, F6-3, and F6-5.
