4.2. Installation and configuration
Important safety instructions
Installation and wiring must be performed by qualified personnel, and in accordance with the local electrical regulations and
codes. Also, you must observe the following guidelines:
1. Make sure the mains wire and breakers in the building are enough for the rated capacity of the UPS to avoid the hazards of electric
shock or fire.
Do not use the wall receptacle as the input power source for the UPS, as its
rated current is less than the UPS's maximum input current. Failure to do so may result in a broken or burned out receptacle.
2. For safety considerations, turn off the mains switch in the building before installation.
3. Turn off and shut down the connected UPS
4. Wiring sizes should be installed in accordance with the following table:
NOTE 1: The cable for 6K/6KL should be able to withstand currents of over 40A. It is recommended to use a 6 AWG or thicker wire for
safety and efficiency.
NOTE 2: The cable for 10K/10KL should be able to withstand currents of over 63A. It is recommended to use an 4 AWG or thicker wire
for safety and efficiency.
NOTE 3: The color selection of wires should be made according to the local electrical codes and regulations.
5. Remove the terminal block cover on the rear panel of the bypass switch module. Then connect the wires according to the terminal
block diagrams included in the section below.
4.3. Connection of the UPS to the external maintenance bypass switch module
1. Remove the terminal block cover on the rear panel of the bypass switch module.
2. Then connect the output terminals of the UPS to the UPS output terminals located on the bypass switch module.
3. Proceed to connect the utility input terminals of the UPS to the UPS input terminals on the bypass switch module.
4. Connect the signal slots of the UPS and the switch module using the supplied signal control cable.
5. Connect main utility line to utility input on the bypass switch module.
6. Finish by connecting the desired load to the bypass switch module output terminals (load).
