3 Terms and definitions
The following terms and definitions apply to this Standard.
3.1 Modular uninterruptible power system
It is composed of input distribution, output distribution, power module, and
control module. The modules are possessed of the following properties.
– Have independent mechanical framework;
– Have complete and independent function;
– The modules shall work cooperatively.
3.2 Power module
It includes rectification, inversion, charging (optional), power factor correction,
and relevant control circuits. As the main module of the UPS system, the power
module has hot swapped function and parallel redundancy operation function
under the normal operating mode of the UPS system.
3.3 Control module
It shall be responsible for the real-time monitoring of the operating mode of the
UPS system as well as the collection and storage of the operating parameters,
5.5.3 Output overload protection of power modules
When the power module’s output exceeds the rated load, the UPS system shall
give an audible and visual alarm; when the power module’s output exceeds its
overload capacity, EXIT the UPS system; when all the power modules in the
UPS system exceed the overload capacity, SWITCH to bypass for power supply.
5.5.4 Over-temperature protection
When the internal temperature of the power module comes up to the protection
settings, the power module shall be able to automatically give an alarm, exit the
system for protection, and return back to the operating mode after
troubleshooting.
5.5.5 Low battery voltage protection
When the UPS system is in battery inverter mode, and the battery voltage
reduces to the protection point, the UPS system shall give an audible and visual
alarm, and the battery shall stop providing power supply.
Note. When the mains power supply recovers after the shutdown caused by battery discharge termination,
users can set whether the system can automatically restart.
5.5.6 Output over-voltage and under-voltage protection
When the inverter output voltage of the UPS system exceeds the over-voltage
and under-voltage set values, the UPS system shall give an audible and visual
alarm, and shall switch to bypass for power supply.
5.5.7 Module fuse (or breaker) protection
The main circuit of the power module shall set fuse (or breaker) protection, so
as to restrict further expansion of certain faults.
5.5.8 System fuse (or breaker) protection
The AC main input, bypass input, and AC output of the UPS system shall be
respectively equipped with fuse (or breaker), and other protective equipment.
5.6 Fan fault alarm
The UPS system shall give an audible and visual alarm when the fan breaks
down.
5.7 Lightning protection performance
The lightning withstand current ratings and technical requirements of the UPS
5.15.3.1 The touch current of the UPS system’s protective earth (PE) to the
input neutral (N) shall not be greater than 3.5mA.
5.15.3.2 When the touch current is greater than 3.5mA, the effective value of
the protective conductor current shall not exceed 5% of the input current per
phase. If the loads are unbalanced, USE the maximum among 3 phase current
valu...
