Installation 2.5.2 Transformer-Based UPS Cable Connection NOTE After the output transformer is installed, if the startup is on bypass, the UPS has a six-cycle inrush current that is up to 20 times the rated output current. This must be taken into account when selecting the input overload protection device at the AC input supply distribution point.
Installation Configuring the Bypass Voltage The UPS bypass voltage is factory-set to 208V (the jumper copper bar has been installed). Should the user have a utility supply of 200V/220V/230V/240V, the bypass voltage jumper must be changed to ensure correct output voltages when in bypass mode. Configuring the bypass voltage jumper settings are shown in Figures 34 and 35. Refer to Table 9 for the proper setting according to the AC mains voltage configuration.
Installation Configuring the Neutral/Earth Jumper The UPS contains an isolation transformer that generates a neutral conductor for the connected load. The UPS is a separately derived source and contains a neutral/earth jumper. A factory-installed neutral/earth jumper copper bar may require removal to comply with local codes and regulations.
