The power supply for the FusionDC1000 can be the mains or a diesel
generator (DG). For the detailed input routes and capacity, see the power
supply and distribution system diagram for the solution in use.
The supported power supply system is 380 V, 50 Hz/60 Hz, three-phase, four-
wire, and PE.
A Class I surge protective device (SPD) with a maximum discharge current
(I ) no less than 100 kA (8/20 µs) is required for the upstream input power
max
distribution frame (PDF) for the FusionDC1000.
External cables of the FusionDC1000 are connected to the pre-fab. module
through the power PDB and feeder window of the pre-fab. module. It is
recommended that external cables be buried underground.
NO TICE
● The prefabricated modular data center product contains devices with large
leakage currents. Do not configure a circuit breaker that has the leakage
current protection function.
● If a "high electricity leakage" tag is attached on the equipment, ground the
protective ground terminal on the equipment enclosure before connecting
the AC power supply; otherwise, electric shock as a result of electricity
leakage may occur.
