2Installing a UPS
1. Carefully read the UPS2000-G-6KRTLL User Manual prior to installation to get familiar with
product information and safety precautions.
2. Use fully insulated tools during installation and operation.
3. Only engineers certified by the manufacturer or its agent are allowed to install, commission,
and maintain the UPS. Otherwise, personal injury or equipment damage may occur, and the
UPS faults caused are beyond the warranty scope of Huawei.
Rack-Mounting the UPS2000-G
Scenario
1. Reserve a space of 1 U in the middle of four batteries for routing battery power cables.
2. Reserve a space of 5 cm between the battery communications port and the cabinet for
installing a communications cable.
3. Reserve a space of 44 mm between the battery edge and the rack edge for installing
battery power cables.
4. In rack-mounted installation scenarios, the front panels of the UPS and lithium batteries
are not on the same plane.
5. The guide rails for the UPS2000-G-6KRTLL are 592.37 mm to 807.37 mm long, 30 mm
wide, and 87 mm high. The guide rails are scalable and support Huawei M-shaped cabinets.
1. Install mounting brackets on UPS.

3Installing Cables
•Connect UPS AC input and output power cables in the same phase sequence. Connect battery
terminals correctly.
•Before connecting cables to the UPS, ensure that the input, output, and battery circuit breakers
are OFF to prevent operations with power applied.
Installing Cables for a Single UPS
Scenario 1
Wiring Terminal Input (AC INPUT) Output (AC OUTPUT)
External Circuit Breaker 32 A
Earth Leakage Circuit Breaker 100 mA -
Cable Cross-sectional Area 6 mm²
Terminal Type OT-6 mm2-M5 terminal
Torque for Tightening Bolts 2 N·m

1. The UPS2000-G-6KRTLL needs to connect to external lithium batteries ESM-48100B1 or
ESM-48150B1. Each UPS supports a maximum of 16 batteries connected in parallel. This
document uses four lithium batteries connected in parallel as an example.
2. When lithium batteries are connected, it is recommended that a DC circuit breaker (150 A 80
V DC circuit breaker for the 6 kVA UPS) be installed between the lithium batteries and the
UPS.
3. Before connecting cables to the UPS, ensure that the battery circuit breakers are OFF to
prevent operations with power applied.
4. If the UPS shares a battery string, the PE bar and battery busbar are configured.
Wiring Terminal Battery (BATT. 48VDC)
External Circuit Breaker 125 A (type D)
Cable Cross-sectional Area 25 mm²
Terminal Type OT-25 mm2-M8 terminal
Torque for Tightening Bolts 7 N·m
2. Install battery cables.
After lithium batteries are connected in parallel, connect signal cables to the BMS ports on
the UPS. Install a build-out resistor at the COM-OUT port on the last lithium battery.

Installing Cables for Parallel UPSs
Scenario 2
•Before parallel running, ensure that all output circuit breakers for each UPS are ON.
Otherwise, a UPS fault (error code #72) will occur.
•Batteries must be connected for parallel running.

Installing Communications Cables
3.2
1. The USB channel supports a serial data communications protocol between the UPS and a PC.
2. If you connect a DB9 connector to the RS232 port, the UPS can exchange data with the PC
over serial communication.
3. You can use only either USB or RS232.
Install parallel communications cables and parallel current equalization cables. Three UPSs
connected in parallel are used as an example.

Item
Expected Result
1
Cable routing
Cables are routed properly according to engineering
requirements.
2
Cable connection
All cables are connected securely and correctly, and they are free
of damage. Bolts are tightened to specified torque using a torque
wrench.
3
Cable connection to USB,
network, and other ports
Signal cables to USB, network, and other ports are connected
securely and correctly.
4
Cable labels
Labels are neatly attached to both ends of each cable, and the
information on the labels is concise and legible.
5
Ground cable connection
The UPS ground cable is securely connected to the equipment
room ground bar. Use a
multimeter to measure the resistance
between the UPS ground cable and the equipment room ground
bar. The resistance is less than 0.1 ohm.
6
Spacing between cable
ties
Distances between cable ties are the same, and no burr exists.
7
Operating environment
The inside and outside of the cabinet are free from conductive
dust or other sundries.
