Intelligent equipment communication protocol 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 values for calculation. On the large current path of the protective conductor, the cross-sectional area of the protective conductor shall not be less than 1.0mm2. SET warning or similar signs at the primary power connection terminal close to the equipment. 5.16 Reliability 5.16.1 Module MTBF Under normal environmental conditions for operation, the module mean time between failures (MTBF) of the UPS system shall not be less than 5 × 104h (without storage batteries). 5.16.2 System MTBF Under normal environmental conditions for operation, the mean time between failures (MTBF) of the UPS system shall not be less than 1 × 105h (without storage batteries). 5.16.3 System MTTR Under normal environmental conditions for operation, the mean time to repair (MTTR) of the UPS system shall not be greater than 0.5h (without storage batteries). 6 Test methods 6.1 Appearance and structure The equipment appearance and structure visual inspections shall conform to the requirements specified in the Section 5.2 of this Standard. 6.2 Input voltage range The test circuit is shown in Figure 1. CONNECT the input with the rated linear load. Respectively ADJUST the AC input voltage to the upper and lower limits specified in Table 1. The UPS system can operate normally, and the output voltage shall not exceed the value specified in Table 1 in the process of input voltage adjustment. and frequency of the UPS system to the rated values. Respectively CONNECT the output with 50% and 100% rated non-linear loads. In normal operating mode of the UPS system, USE a power harmonic analyzer to measure ... ......
