Single Ups Installation - Emerson Liebert GXT MT+LB 10KL User Manual

2-3. Single UPS Installation

Installation and wiring must be performed in accordance with the local electric laws/regulations and execute the
following instructions by professional personnel.
1) Make sure the mains wire and breakers in the building are in compliance with the standard of rated
capacity of UPS to avoid the hazards of electric shock or 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. Otherwise the receptacle may be burned 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
Input
10K
10KL
NOTE 1: The cable for 6K/6KL should be able to withstand over 50A current. It is recommended to use
10AWG or thicker wire for safety and efficiency.
NOTE 2: The cable for 10K/10KL should be able to withstand over 63A current. It is recommended to use
8AWG or thicker wire for safety and efficiency.
NOTE 3: The selections for color of wires should be followed by the local electrical laws and regulations.
5) Remove the terminal block cover on the rear panel of UPS. Then connect the wires according to the
following terminal block diagrams: (Connect the earth wire first when making wire connection. Disconnect the
earth wire last when making wire disconnection!)
NOTE 1: Make sure that the wires are connected tightly with the terminals.
NOTE 2: 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.
NOTE 3: For single operation, the terminals of "BPS" and "L0" must be shorted.
6) Put the terminal block cover back to the rear panel of the UPS.
