2.3 Power Supply and Distribution Requirements
● 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
max
) no less than 100 kA (8/20 µs) is required for the upstream input power
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.
● The prefabricated modular data center product contains devices with large
leakage currents. Do not congure 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.
