1. Before installation, read the user manual carefully to get familiar with product information and safety precautions.
2. Use insulated tools during installation and operation.
3. Only engineers certified by the manufacturer or its agents are allowed to perform UPS installation, commissioning, and maintenance. Otherwise, personal injury or equipment damage may occur, and the resulting UPS faults are beyond the warranty scope.
4. This document describes how to install a single UPS. For details about how to install parallel systems, contact Huawei technical support.

Installing the UPS

2.1 Determining the UPS Installation Position

1. Channel steels and expansion bolts for securing the channel steels should be purchased by the customer. The recommended channel steel width is 50 mm or more.
2. Ensure that the spacing between external sides of a channel steel is 800 mm. Secure channel steels to the ground by using expansion bolts.

Scenario A: Channel steel mounting hole
Scenario B: Mounting holes on the floor
Unit: mm 2.2 Securing the UPS

• Floor mounting: Use eight M12x60 expansion bolts to secure the cabinet to the ground.
• Channel steel mounting: Use eight M12x60 common bolts to secure the cabinet to channel steels.

(1) Cabinet mounting holes (ground installation mode)
(2) Cabinet mounting holes (channel steel installation mode) 2.3 Install the front, rear, left, and right anchor baffle plates

Connecting Cables

NOTE

1. This document describes cable routing by removing the top cover when there are two mains inputs.
2. In the case of single mains, you do not need to connect bypass input power cables and remove short-circuit copper bars.

3.1 UPS Cable Connection Reference
WARNING

• Prepare cables away from the cabinets to prevent scraps from falling inside. Cable scraps may ignite and cause personal injury or device damage.
• After cables have been installed, clean the cabinets in a timely manner. Keep the cabinets and surrounding environment clean and tidy.
• You need to prepare terminals onsite. The stripped length of the copper wire should be the same as that of the part of the terminal that covers the conductor.

NOTE
The cabling route is for reference only. Connect cables based on site requirements.
3.2 Connecting Cables
Scenario 1: Routing Cables from the Top

1. Open the front door of the bypass cabinet, and remove front power distribution covers.

2. Remove the cable covers from the top of the cabinet. Then remove the beam, which is an optional step.

3. Remove the rear cover from the bypass cabinet, and then remove the connecting copper bars between mains input terminals and bypass input terminals. (If the mains input and bypass input share a power source, skip this step.)

4. Connect the ground cable to the UPS.

5. Connect the mains input power cable.

6. Connect the output power cable.

7. Connect bypass input power cables.

8. Connect the battery cable. NOTE
   Route a neutral wire from the middle of the positive and negative battery strings. Take a battery string consisting of 40 batteries as an example. A neutral wire is routed from the middle of positive and negative battery strings, each consisting of 20 batteries.

9. Connect signal cables.

Scenario 2: Routing Cables from the Bottom

1. Remove the cable covers from the bottom of the cabinet, drill holes in the covers, attach grommet strips to the hole edges for protecting cables, and reinstall the cable covers.
2. Connect power cables and signal cables.

NOTE
For the screw specifications and torque used for connecting cables in a bottom cable routing scenario, refer to the top cable routing scenario. This section only shows the cable routes in the bottom cable routing scenario.

Installation Verification

1. Check that there is no foreign matter in the cabinet.(1) Switches
   (2) Mains input wiring copper bars
   (3) Battery input wiring copper bars
   (4) Output wiring copper bars
   (5) Bypass input wiring copper bars
   (6) Cabinet rear

2. After verifying the installation, reinstall all the covers.

3. (Remove the paper protective film from the sealing putty.) After routing cables and verifying cable connections, seal the gap between cables and the cabinet using sealing putty.
   NOTICE
   Sealing putty must be used as a whole and the gap can be sealed only from the top.

4. Do not remove the dustproof cover before power-on to prevent dust inside the UPS.

Powering On and Starting the UPS

NOTICE

1. Before powering on the UPS, ensure that the UPS has passed all check items in the UPS5000 Commissioning and Acceptance Report and Chapter 4.
2. Measure the voltage and frequency of the UPS upstream input switch. The line voltage range is 138–485 V AC, and the frequency range is 40–70 Hz.

5.1 Powering On the UPS 5.2 Initial Startup

1. Obtain the startup password through the app. After the application is approved, enter the password on the service authorization screen of the device to complete device authorization.
   NOTICE
   Technical support engineers can obtain the service authorization code through the app. For details, see the Data Center Facility Deployment Guide.

2. Set the language, time, date, network parameters, and system parameters on the Settings Wizard screen.

3. After you perform the settings, the Bypass mode and No battery alarms are reported by the MDU and do not need to be cleared. If there is any other alarm, you need to rectify the fault.

4. If the system has connected to the remote EPO switch, you need to choose Monitoring > UPS System > Running Parameter > System Settings on the WebUI and set EPO detection to Enable.

5. View the system running status diagram on the MDU to check that the UPS is working in bypass mode.

5.3 Starting inverter

1. On the main menu, choose Common Functions and tap Inv. ON.
2. In the displayed login window, enter the user name and password, and tap .
3. In the displayed dialog box, tap Yes to start the inverter.

NOTE
To ensure system security, change the LCD and WebUI passwords after the first login.

5.4 Powering On Loads

1. After the inverter starts, the UPS works in normal mode. The Bypass mode alarm disappears from the MDU.
2. After confirming that the battery strings are properly connected, turn on the battery string input circuit breaker. If there are multiple battery strings, turn on the circuit breaker for each battery string and then turn on the general circuit breaker between battery strings and the UPS. The No battery alarm disappears from the MDU.
3. Turn on the UPS downstream output switch to supply power to the loads.

5.5 (Optional) Setting Parameters for the BCB Box

1. If a BCB box is configured, set MUE05A connection to Enable in System Info > Settings > Dry Contacts Set, and then set BCB connection [OL] and Battery breaker [STA] to Enable.

Shutting Down the UPS

After you shut down the inverter, the UPS transfers to bypass mode if the bypass is normal; the UPS supplies no power if the bypass is abnormal. Before shutting down the UPS, ensure that all loads have been shut down.
6.1 Shutting Down the Inverter to Transfer the UPS to Bypass Mode

1. On the main menu of the LCD, choose Common Functions and tap Inv. OFF.
2. In the displayed login window, enter the user name and password, and tap .
3. In the displayed dialog box, tap Yes to shut down the inverter.
