1. Carefully read the

UPS2000-G-(6 kVA–20 kVA) User Manual

prior to installation to get familiar

with product information and safety precautions.

2. Use insulated tools during installation.

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 resulting

UPS faults are beyond the warranty scope of Huawei.

Method 2: If there are adjustable guide

rails, install two adjustable guide rails and

two floating nuts.

Method 1: If there are no adjustable

guide rails, install six floating nuts.

3. Install guide rails using either of the methods.

Adjustable guide rails

Avoid pushing guide rails out of the rack

when placing the battery pack, power

distribution unit (PDU), and UPS on the

rack because the front ends of the guide

rails are not screwed. The length of guide

rails ranges from 592.37 mm to 807.37

mm, the width is 30 mm, and the height

is 87 mm. The guide rails are scalable and

support Huawei M-type cabinets.

Tower-Mounted Installation

Scenario 2

2Installing AC Input and Output Power Cables

1. bL indicates the bypass input, and mL indicates the mains input.

2. Connect UPS AC input and output power cables in the same phase sequence. Connect

battery terminals correctly.

3. Before connecting cables to the UPS, ensure that the input circuit breaker, output circuit

breaker, and battery circuit breaker are OFF to prevent operations with power on.

4. If the input or output wiring has to be changed, contact Huawei technical support if you are

not familiar with the operation. Do not power on the UPS directly.

5. If the input or output system is changed, ensure that the short-circuit copper bar status and

cable connections at input and output ports are correct.

6. The copper bar and ground screws are M6. Tighten them to 4.8 N·m. The chassis screws are

M5. Tighten them to 2.8 N·m.

7. In a single UPS system, connect loads to AC OUTPUT sL and pL terminals. Connect primary

loads to the sL terminal and secondary loads to the pL terminal. For a parallel system,

connect loads to the AC OUTPUT pL terminal, instead of the sL terminal.

8. The UPS can generate large leakage currents. A circuit breaker equipped with a residual

current device (RCD) is not recommended. If leakage protection is required, select a

recommended circuit breaker.

9. When installing short-circuit bars, install the AC INPUT short-circuit bar and cables, and then

install the AC OUTPUT short-circuit bar and cables.

10.The cable colors in the figures are for reference only.

1. If the AC input of the 15 kVA/20 kVA UPS uses two live wires, connect bypass and mains

inputs bL1, bL2, bL3, mL1, mL2, and mL3 that are short-circuited with a short-circuit bar to

live wire L1, and connect the input N and N with a short-circuit bar to live wire L2.

2. If the AC input and AC output uses two live wires, the input and output must be connected

to two-pole circuit breakers provided by the customer.

1. The UPS2000-G-15KRTL/20KRTL can connect to an external battery string (40 batteries

in the standard configuration, and an even number of 32 to 40 batteries are supported).

The neutral wire is connected to the middle point of the battery string. For example, if

there are 40 batteries, the neutral wire is connected to the negative terminal of the

twentieth battery.

2. When an external battery string is connected, install a DC circuit breaker (63 A, 600 V

DC) between the battery string and the UPS.

3. When an external battery string is connected, connect positive terminals in series by

using the two poles of the DC circuit breaker.

Scenario 2

1. A 15 kVA/20 kVA UPS with long backup time requires serial connection of two battery packs

in each group. A maximum of four groups with eight battery packs can be connected in

parallel. If more than two battery packs need to be connected to the 15 kVA/20 kVA UPS

with long backup time, the battery packs should be connected in parallel and then

connected to the battery input ports of the UPS, as shown in the following figure. Connect

battery packs 1 and 2 in series, battery packs 3 and 4 in series, battery packs 5 and 6 in

series, and battery packs 7 and 8 in series. Connect battery packs 1, 3, 5, and 7 in parallel

and battery packs 2, 4, 6, and 8 in parallel.
