The automated electric generator must have a standard interface that supports
telecommunication protocols, remote telecommunication, monitoring, and control.
AC power cables should meet the following specifications:

Requirements for DC Power Supply
The equipment room should receive stable and reliable DC power. Deploy the
power equipment near the telecommunications equipment to make the DC feeder

AC neutral should have a conductor with the same cross section as the phase
line.
AC cables should have non-flammable insulation. The layout of AC cables
should comply with local regulations. Low-voltage power distribution rooms
should comply with local regulations.
If the voltage of the power mains that supply power directly to devices
exceeds the rated voltage by -10% to 5%, or exceeds the voltage range that
devices can support, a voltage regulating device or voltage stabilizing device
is required.
If the mains do not supply power for the device directly, or if the mains
voltage exceeds the rated voltage by -15% to 10% or exceeds the input
voltage range of the DC power supply, a voltage regulating device or voltage
stabilizing device is required.
A UPS or inverter power supply system is required to provide uninterrupted
AC power to support the telecommunication load.
If abnormalities occur on the mains, telecommunication servers should be
equipped with a self-supplied electric generator to support the key
telecommunication load. The capacity should be not less than 150% to 200%
of the total uninterruptible power supply.
Storage batteries are usually installed in a parallel connection of two groups.
UPS storage batteries are generally installed in one group. The redundancy
required for the UPS can rely on concatenation or parallel connection. When
an inverter or a UPS is used, the active inverter is determined by the
maximum power and a backup inverter is required.
