3.3.3 Single wiring
After fully positioning the equipment, connect the power cord according to the following steps:
Make sure that all the input power distribution switches and internal power switches of UPS
have been completely disconnected. Stick warning labels on these switches, so as to
prevent others from conducting incorrect operations to the switches.
Remove the cover plate of the terminal block below the UPS rear panel, so as to expose
the terminal block connected with the power cable.
Ground connection:
Connect the protective grounding cable and other necessary grounding cables to the ground
terminal of the UPS terminal block. All the UPS cabinets must be connected with the user grounding
cable.
Mains and bypass input wiring:
During the assembly, the bypass input cable L and the mains input cable L (1-phase
in/1-phase out UPS), or the mains input cable C (3-phase in/1-phase out UPS) have
been short-circuited on the terminal block.
When the bypass and the mains power use the same mains input, the AC input cable
shall be connected with the UPS mains input terminal. Make sure that the bypass input
cable L and the mains input cable L (1-phase in/1-phase out UPS), or the mains input
cable C (3-phase in/1-phase out UPS) are short-circuited. Furthermore, make sure
that the live wire and the neutral wire are properly connected according to the label of
terminal block.
