3. Installation and Setup 3.4 Single UPS Installation Installation and wiring must be performed in accordance with local electrical codes/regulations and should only be performed by qualified personnel. 1) Make sure the mains wire and breakers in the building can sustain the rated capacity of the UPS to avoid the hazards of electric shock or fire. Note: Using a wall receptacle as the input power source for the UPS may result in the receptacle burning or otherwise being destroyed. 2) Switch off the mains switch in the building prior to installation. 3) Turn off all the connected devices before connecting to the UPS. 4) Prepare wires based on the following table: Wiring spec (AWG) [cross-sectional area in mm2] Model Input (Ph) Output (Ph) Neutral Cable Length Ground SVT10KX 10 [5] 10 [5] 8 [8] 10 Meters Maximum 8 [8] SVT20KX 8 [8] 8 [8] 6 [13] 10 Meters Maximum 6 [13] SVT30KX 6 [10] 6 [10] 4 [21] 10 Meters Maximum 4 [21] Notes: • The SVT10KX cable should be able to withstand over 40A current. It is recommended to use 10 AWG or thicker wire for Phase and 8 AWG or thicker wire for Neutral. • The SVT20KX cable should be able to withstand over 63A current. It is recommended to use 8 AWG or thicker wire for Phase and 6 AWG or thicker wire for Neutral. • The SVT30KX cable should be able to withstand over 63A current. It is recommended to use 6 AWG or thicker wire for Phase and 4 AWG or thicker wire for Neutral. • The selection of wire color should follow local electrical codes and regulations. 5) Remove the terminal block cover to access the UPS system's input, output and grounding connection terminals. Circular knockouts must be made on the terminal block cover to allow wiring conduits to pass through. Notes: • Make sure the wires are connected tightly to the terminals. • Install the output breaker between the output terminal and the load. The breaker should be qualified with leakage current protective function. • Cabling should be protected by flexible conduit and routed through the appropriate knockouts in the terminal block cover. 6) Replace the terminal block cover of the UPS system with flexible conduit attached. Terminal Block Wiring Diagram (All Models) Warning: Make sure the UPS is not turned on prior to installation. The UPS should not be turned on until all wiring has been completed and checked. Warning: If an external battery pack is installed, switch off the battery breaker before installation. Note: Set the battery pack breaker in the "OFF" position, then install the battery pack. • Pay close attention to the rated battery voltage posted on the rear panel. Connecting battery packs with the incorrect voltage may cause permanent damage to the UPS. • Pay close attention to the polarity markings on the external battery terminal block and make sure the correct battery polarity is connected. Wrong connection may cause permanent damage to the UPS. • Ensure the protective earth ground wiring is correct. The wire current spec, color, position, connection and conductance reliability should be carefully observed. • Ensure the utility input and output wiring is correct. The wire current spec, color, position, connection and conductance reliability should be checked carefully. Make sure the R, S, T and N wiring is correct, not reversed and not short-circuited. 9

Installation and wiring must be performed in accordance with local electrical codes/regulations and should only be performed by qualified
personnel.
1) Make sure the mains wire and breakers in the building can sustain the rated capacity of the UPS to avoid the hazards of electric
shock or fire.
Note:
Using a wall receptacle as the input power source for the UPS may result in the receptacle burning or otherwise being destroyed.
2) Switch off the mains switch in the building prior to installation.
3) Turn off all the connected devices before connecting to the UPS.
4) Prepare wires based on the following table:
