Rubber plug Battery pack (optional, 3 U) UPS (3 U) 2 Installing 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. 5 Connect cables based on the actual situation.

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.

If an alarm is displayed, clear the alarm. 8.4 Starting the Inverters 1. Check that the bypass input is normal and the UPS has transferred to bypass mode by viewing the system running status on the LCD. After you perform "startup operations" on UPS 1 to UPS n one by one, UPS 1 to UPS n are starting. If you do not perform "startup operations" on the other UPSs in 5 minutes, UPS 1 to UPS n enter normal mode, and the other UPSs supply no power. 2. Perform "startup operations" on each UPS in the parallel system: On the standby screen, hold down for more than 5 seconds. Release the button when you hear a beep sound. The startup screen is displayed. After the UPS starts successfully, it enters normal mode. 3. After the parallel system runs properly, switch on the general AC output circuit breaker Q for the UPSs and start each load. To prevent triggering overload protection, start the loads with higher power and then loads with lower power. 32 9 Shutdown 9.1 Shutting Down a Single UPS in the Parallel System Perform "shutdown operations" to shut down the UPS: On the default screen, hold down ESC for more than 5 seconds. Release the button when you hear a beep sound. The inverter shuts down. If the bypass voltage is within the configured range, the UPS transfers to bypass mode. If the bypass voltage is beyond the configured range, the UPS has no output. 1. Perform "shutdown operations" twice on a UPS in the parallel system within 30 seconds. The UPS shuts down and enters the non-output state (the mains, bypass, and battery indicators are off). The other UPSs keep working. 2. Switch off the AC input circuit breakers (K1, Km1, Kb1 or K2, Km2, Kb2) and AC output circuit breaker (Q1 or Q2) of the UPS based on site requirements. 3. Turn off the external battery circuit breakers (if there are), or disconnect battery power cables (if there is no battery circuit breaker). The UPS exits the parallel system. After all indicators turn off and fans stop, the UPS shuts down. 9.2 Transferring a Parallel System to Bypass Mode Perform "shutdown operations" on each UPS in the parallel system. The inverters shut down. If the bypass voltage is within the configured range, the UPS transfers to bypass mode. If the bypass voltage is beyond the configured range, the UPS has no output. 9.3 Powering Off a Parallel System 1. Shut down loads. 2. Perform "shutdown operations" on each UPS in the parallel system. The inverters shut down. If the bypass voltage is within the configured range, the UPS transfers to bypass mode. If the bypass voltage is beyond the configured range, the UPS has no output. 3. Switch off the AC input circuit breakers (K1, Km1, Kb1, K2, Km2, Kb2) of each UPS, general input circuit breakers (K, Km, and Kb) of the UPS system, AC output circuit breakers (Q1 and Q2) of each UPS, and general AC output circuit breaker Q of the UPS system based on site requirements. 4. Switch off the external battery circuit breaker for each UPS or the general battery circuit breaker (when all UPSs share a battery string). If no external battery circuit breaker is configured, disconnect battery cables from each UPS. After all indicators turn off and fans stop, the UPS shuts down, and the loads power off. 33 Typical Alarm Handling For more parameters and alarm information, see UPS2000-G-(6 kVA-20 kVA) User Manual.

Rectifier fault 0040-04 Internal fault 0042-10 Fan fault 0043-01 Minor Critical Critical Critical Automatic Manual/Po weroff/Autom atic Automatic Automatic An alarm is displayed, and the system may shut down due to EOD. The UPS shuts down. The UPS transfers to another working mode or shuts down. If the inverter has not started, disable inverter startup. If the inverter has started, the UPS can work in inverter mode properly, but the UPS cannot transfer to bypass mode. This alarm does not affect the UPS or the power supply. Possible cause: The mains is abnormal, and the batteries are overdischarged. Measure: Connect to the mains supply in non-battery test state. Possible causes: · The mains has experienced a transient high voltage. · The output carries special loads such as inductive and rectification loads. · The output carries transformer loads but the transformer mode is not enabled. · The hardware is damaged. Measures: · Rectify the fault and power on the UPS again. · Check that the loads are supported by the UPS. · Enable the transformer mode. · Contact Huawei technical support. Possible cause: The bypass input cable connection is inconsistent with the output system setting. Measure: Ensure that the bypass input cable connection is consistent with the output system setting. Possible cause: The fan is abnormal. Measure: Clean up foreign objects around the fan.
