3.4 Selection of Cable
3.4.1 Selection of Input Air Switch
Before the input coil in of the equipment, install an air switch or a distribution
box compliant with the power and capability of the equipment, to isolate it with
commercial power. Consider especially the charge power and the current
shock, the input air switch can be higher than 1.5-2 times most current of UPS
input, which is without creepage protection in order to avoid error action. The
distribution box should be better to be manufactured by professional company.
Please refer to Table 3-1.
