2.4. Single UPS installation
Installation and wiring must be carried out in accordance with the local
electric laws and regulations by trained professionals.
Step 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.
Step 2.
Switch off the mains switch in the building before installation.
Step 3.
Turn off all the connected devices before connecting to the UPS.
Step 4.
Prepare wires based on the following table:
Wiring spec (minimum A cable should support)
Model
Input (Ph)
Output (Ph)
Ranger
290A
290A
180KT
• The cables for Ranger 180KT should be able to withstand over 290A
current for Input and Output phase, 500A for Neutral, 560A for battery
cabinet and 290A for Ground. Please use corresponding thickness for each
wire.
Step 5.
Remove the terminal block cover at the rear panel of UPS. Then
connect the wires according to the following terminal block diagrams: (In case
power wires need to be connected please connect the grounding/earthing wire
first. On the contrary, in case you want to disconnect the power wires then please
disconnect the grounding/earthing wire last.)

NOTE!
Please install the output breaker between the output terminal and the load,
and the breaker should be qualified with leakage current protective function
if necessary.

• Make sure that the wires are connected tightly with the terminals.
Step 6.
Put the terminal block cover back at the rear panel of the UPS.
IMPORTANT!
• Make sure a DC breaker or other protective device between UPS and the
external battery pack is installed. If not, please install it carefully. Switch off
the battery breaker before installation.
• Set the battery pack breaker in "OFF" position and then install the battery pack.
• Pay high attention to the rated battery voltage marked on the rear panel.
If you want to change the numbers of the battery pack, please make sure
you modify the setting simultaneously. The connection with wrong battery
voltage may cause permanent damage of the UPS. Make sure the voltage of
the battery pack is correct.
• Pay high attention to the polarity marking on external battery terminal
block. And make sure the correct battery polarity is connected. Wrong
connection may cause permanent damage of the UPS.
• Make sure the protective earth ground wiring is correct. The wire current
spec, color, position, connection and conductance reliability should be
checked carefully.
• Make sure the utility input & output wire is correct. The wire current spec,
color, position, connection and conductance reliability should be checked
carefully. Make sure the L/N side is correct, not reverse or short-circuited.
