2-3. Single UPS Installation

Installation and wiring must be carried out in accordance with the local electric laws and regulations by
trained professionals.
1) Make sure that the mains wire and breakers of the building are rated for the capacity of the UPS to
prevent electric shock or risk of fire.
NOTE: 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. The receptacle may be damaged and destroyed.
2) Switch off the mains switch in the building before installation.
3) Turn off all the connected devices before connecting to the UPS.
4) Prepare wires based on the following table:
Model
HV 10KL /LV 5KL
HV 15KL / LV 7.5KL
LV 10K/ HV 20K
NOTE 1: The cable for HV 10KL and LV 5KL should be able to withstand over 20A current. It is
recommended to use AWG 14 or thicker wire for Phase and AWG10 or thicker wire for Neutral for safety
and efficiency.
NOTE 2: The cable for HV 15KL and LV 7.5KL should be able to withstand over 30A current. It is
recommended to use AWG 12 or thicker wire for Phase and AWG10 or thicker wire for Neutral for safety
and efficiency.
NOTE 3: The cable for HV 20KL and LV 10KL should be able to withstand over 40A current. It is
recommended to use AWG10 or thicker wire for Phase and AWG 6 or thicker wire for Neutral for safety
and efficiency.
NOTE 4: The selections for color of wires should be followed by the local electrical laws and
regulations.
5) Remove the terminal block cover at the rear panel of UPS. Then connect the wires according to the
following terminal block diagrams: (Connect the grounding/earthing wire first when making other wire
connections. Remove the grounding/earthing wire last when connecting the UPS!)
NOTE: For dual input model with single input power system, connect input terminals to the AC power
source and connect input and bypass input together (shows dashed line in below wiring diagrams)
