Installing a UPS

NOTE

• The installation of the 6 kVA UPS is similar to that of the 10 kVA UPS. This document uses the 6 kVA UPS as an example. Perform operations based on the actual situation.
• A UPS supports a maximum of eight lithium batteries in parallel.
• It is recommended that the BBB box be installed behind the lithium batteries.
• If four groups of batteries are installed in the rack-mounted mode, reserve 1 U space between every two groups of lithium batteries battery cables.
• You are advised to reserve 1 U space between UPSs, 1 U space between the UPS and lithium battery, and 1 U space above the UPS.

Typical Tower-mounted Scenario

NOTE

• The following uses one 6 kVA UPS and four lithium batteries in tower-mounted mode with a junction box as an example.
• A subrack can house a maximum of three devices and only one UPS is supported.
• In a single-server scenario, if more than six lithium batteries are installed, two junction boxes need to be installed.

Installing Cables

Installing AC Power Cables (Single UPS)

1. Connect UPS AC input and output power cables in the same phase sequence. Connect battery terminals correctly.
2. Before connecting cables to the UPS, ensure that the input circuit breaker and output circuit breaker are OFF to prevent operations with power on.
3. If the input or output cables has to be changed, contact Huawei technical support if you are not familiar with the operation. Do not power on the UPS directly.
4. 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.
5. 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.
   6. K1: UPS input circuit breaker; Q1: UPS output circuit breaker.

Installing Battery Cables (Single UPS)

NOTE

When replacing a faulty lithium battery, disconnect all loops between the UPS and the battery to prevent maintenance with power on.
Installing AC Power Cables (Parallel System)

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, turn off all circuit breakers in the parallel system.

NOTICE

1. 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.
2. Circuit breakers used for cable connection need to be provided by the customer.
3. 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.
4. K: general AC input circuit breaker; K1: UPS 1 input circuit breaker; K2: UPS 2 input circuit breaker; Q: general AC output circuit breaker; Q1: UPS 1 output circuit breaker; Q2: UPS 2 output circuit breaker; B1–Bn: lithium battery circuit breakers.
