Installing a UPS

NOTICE

Carefully read the UPS2000-G-6KRTLL User Manual prior to installation to get familiar with product information and safety precautions.
Use fully insulated tools during installation and operation.
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.

Scenario Rack-Mounting the UPS2000-G

Reserve a space of 1 U in the middle of four batteries for routing battery power cables.
Reserve a space of 5 cm between the battery communications port and the cabinet for installing a communications cable.
Reserve a space of 44 mm between the battery edge and the rack edge for installing battery power cables.
In rack-mounted installation scenarios, the front panels of the UPS and lithium batteries are not on the same plane.
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
2. Install devices from bottom to top, as shown in the

Installing Cables

WARNING

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 Power Cables

Scenario 1 Installing Cables for a Single UPS

Install AC input and output power cables.

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

Install battery cables.

NOTE

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.
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.
Before connecting cables to the UPS, ensure that the battery circuit breakers are OFF to prevent operations with power applied.
If the UPS shares a battery string, the PE bar and battery busbar are configured.

Recommended power cable specifications

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

NOTICE
Install a build-out resistor at the COM_OUT port on the last lithium battery

Scenario 2 Installing Cables for Parallel UPSs

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.

Install AC input and output power cables
NOTE
Two UPSs connected in parallel are used as an example

Install parallel communications cables and parallel current equalization cables. In this example, two UPSs are connected in parallel
1. Parallel current equalization cables
2. Parallel communications cables

Installing Communications Cables

NOTE

The USB channel supports a serial data communications protocol between the UPS and a PC.
If you connect a DB9 connector to the RS232 port, the UPS can exchange data with the PC over serial communication.
You can use only either USB or RS232.

Verifying the Installation

No.	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.

Operations

Setting Key UPS Parameters

Switch on the external battery circuit breaker (if any).
Switch on the external AC input circuit breaker (if any) of the UPS. The UPS transfers to the standby mode.
Press and hold SELECT for 1s on a non-setting screen to access the login screen for parameter settings. The initial password is 000001. Enter the correct password to enter the UPS setting mode.
Set the output voltage to 220 V AC or other values based on site requirements. The value can be 220 V AC, 230 V AC (default), or 240 V AC.
In a parallel system, set the number of parallel UPSs to 2 or other values on each UPS based on site requirements. The value is 1 by default and range from 1 to 4.
Set the battery capacity to 100 Ah or other values based on site requirements. The value is 100 Ah by default and can range from 50 Ah to 2400 Ah. The value increases by 50 Ah each time you press the SELECT button
Press ON/MUTE+SELECT to return to the standby screen.

NOTE
For details about parameter settings, see the UPS2000-G-6KRTLL User Manual

Common Settings

Starting the Inverter

On the standby screen, press and hold down ON/MUTE for more than 5 seconds. Release the button when you hear a beep tone. If the UPS starts successfully, it enters the normal mode. After you ensure that the UPS runs properly, switch on the AC output circuit breaker on the UPS and start loads

Shutting Down the Inverter

Shut down loads.
Press and hold down OFF/ENTER for more than 5s. Release the button when you hear the buzzer buzzing. The UPS shuts down the inverter and transfers to bypass mode. If mains parameters are inconsistent with bypass parameters, the UPS transfers to standby mode.
Switch off the UPS AC input circuit breaker (on the power distribution cabinet or external switch) and output circuit breaker (if any) based on site requirements.
Switch off the external battery circuit breaker (if any), or disconnect battery power cables (if there is no external battery circuit breaker).
