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.

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.

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.

1. For UPS2000-G-15KRTL-01/UPS2000-G-20KRTL-
01, choose Settings > System Parameters >
Other Settings and set EPO Enable to Enable.
2. Connect an external switch to the EPO ports of
the UPS. After you turn on the switch in the case
of emergency, the inverter stops and the UPS
does not transfer to bypass mode. In this way,
the UPS stops supplying power immediately.
3. The customer provides the external switch (it can
be a common switch) that connects to the EPO
ports.

2Installing AC Input and Output Power Cables
1. Ensure that the AC input and output power cables on each UPS are connected in the same
phase sequence, battery terminals are connected correctly, and the bypass power cables are
connected in the same phase sequence.
2. Before cable connection, switch off all circuit breakers in the parallel system.
3. 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.
1. 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.
2. 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.
3. 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.
4. Circuit breakers used for cable connection need to be provided by the customer.
5. When UPSs are connected in parallel, the output parallel power cables of each UPS must be
at least 1 m long and the length deviation must be less than ±10%. The four cables must be
connected at the remote end.
6. If the parallel system uses the TN-C power distribution system, install magnetic rings around
the PE cables on each UPS, bind the magnetic rings together using cable ties, and secure the
magnetic rings nearby. Magnetic rings are optional. For details about the model and usage,
see the UPS2000-G-(6 kVA-20 kVA) User Manual .
1. bL indicates the bypass input, and mL indicates the mains input.
2. K indicates the general AC input circuit breaker, Kmindicates the general mains input circuit
breaker, and Kbindicates the general bypass input circuit breaker. K1, Km1, and Kb1 indicate
UPS 1 input circuit breakers. K2, Km2, and Kb2 indicate UPS 2 input circuit breakers. Q
