1.1.1 This standard specifies the general and safety requirements for PS used in areas where personnel are not allowed to come into contact with the equipment. This standard applies to: indirect current transfer systems with electrical energy transfer devices in the power supply circuit. The main function of the uninterruptible power supply system (PS) referred to in this standard is to ensure the continuity of the power supply. The PS can also be used to keep the power supply within the specified characteristics and to improve the quality of the power supply. This standard applies to: mobile, stationary, fixed or dormant LPs intended to be installed in areas where personnel are not allowed to come into contact with the equipment. The standard specifies a series of requirements to ensure the safety of operators and laymen who may come into contact with the equipment, and when specified, also includes the safety of personnel. This standard is intended to ensure the safety of the UPS installed in accordance with the manufacturer's specifications, during installation, operation and maintenance. The UPS installed in the wave can be a single IPS unit, or a system composed of several IPS components.
This standard does not include the TPS of the US-based rotating machine installed in the research area (reduced from the area of ​​​​reduction).
41, for the LPS intended to be used in the tropical home, the vehicle, wheel or +1. The net limit of 100Dm or more may not meet the requirements.
The total negative selection of 2LPS exceeds IFC60664 for more than 1 hour, and the cost of the PS is allowed. Add protection pool,
3: PS can be used with non-water external objects, which may increase the fee. This requirement is shown in H.
Note 4; High temperature: From the beginning, the waveform of the small generator is not complete, and the action of the power grid will not be divided into the power grid. Note that the UPS must be used at the end: 112 Although this standard does not cover all types of LPS, it can also be used for these UPS The Ministry of Information Industry of the People's Republic of China approved 2001-05-17 2001-0E-1 implementation
