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. Install AC input and output power cables.

Installing Power Cables

3.1

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.

No.

Item

Expected Result

Cable routing

Cables are routed properly according to engineering

requirements.

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.

Cable connection to USB,

network, and other ports

Signal cables to USB, network, and other ports are connected

securely and correctly.

Cable labels

Labels are neatly attached to both ends of each cable, and the

information on the labels is concise and legible.

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.

Spacing between cable

ties

Distances between cable ties are the same, and no burr exists.

Operating environment

The inside and outside of the cabinet are free from conductive

dust or other sundries.

Verifying the Installation

Operations

1. Switch on the external battery circuit breaker (if any).

2. Switch on the external AC input circuit breaker (if any). The UPS enters standby mode.

3. Press and hold SELECT for 1s on a non-setting screen to access the login screen for parameter

settings. The initial password is 123. Enter the correct password to access the UPS setting

mode. On the parameter setting screen, press SELECT to select a parameter, and then press

OFF/ENTER. Set parameters as required.

Default output voltage: 230 V AC; options: 220 V AC, 230 V AC, and 240 V AC

Default output frequency: 50 Hz; options: 50 Hz and 60 Hz

Default battery capacity: 4 (200 Ah), 1 (50 Ah) to 48 (2400 Ah). The value increases by 50 Ah

each time you press SELECT.

Default number of parallel UPSs: 1; value range: 1–4
