6.4.8 Auxiliary AC power outputs
The HiPerGuard MV UPS has available two auxiliary 400Vac three-phase power supplies, for use as and when re-
quired.
The first power supply is internally fed, so is continuously available. This may be required, for example, by the En-
ergy Storage enclosure(s) for fan supply.
The second power supply is fed from the external three-phase site supply. Refer to Section 6.4.1.
