2Installing a UPS
1. Carefully read the UPS2000-G-3KRTLL 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 between the UPS and 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.
1. Install the mounting ears on both sides of the 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.

Scenario1
Wiring Terminal Input (AC INPUT) Output (AC OUTPUT)
External Circuit Breaker 16 A
Earth Leakage Circuit Breaker 100 mA -
Cable Cross-sectional Area 2.5 mm²
Terminal Type OT-6 mm2-M5 terminal
Torque for Tightening Bolts 2 N·m

1. The UPS2000-G-3KRTLL needs to connect to external lithium batteries. Each UPS supports a
maximum of eight batteries connected in parallel. This document uses two lithium batteries
connected in parallel as an example.
2. When lithium batteries are connected, it is recommended that a DC circuit breaker (63A 80 V
DC circuit breaker for the 3 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 63 A (type D)
Cable Cross-sectional Area 16 mm²
Terminal Type OT-16 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.

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.
