User Manual 2 Overview

The UPS5000 is an online product. It uses a modular design, which facilitates

maintenance and capacity expansion. The UPS5000 uses the digital signal
processing (DSP) technology for intelligent control. Its power module consists of a
rectifier, inverter, and DC/DC converter. The UPS5000 converts inputs into pure
high-quality sine wave outputs by using the high-frequency switching technology.

Figure 2-2 Conceptual diagram

2.2.2 Working Modes

2.2.2.1 Normal Mode

In normal mode, the rectifier converts AC power into DC power, then the inverter
converts DC power into high-precision AC outputs. The conversions protect loads
from interference such as input harmonics, glitches, and voltage transients.

2.2.2.4 ECO Mode

The economic control operation (ECO) mode is an economical working mode,

which can be configured on the LCD or web user interface (WebUI). In ECO mode,
when the bypass input is within the ECO voltage and frequency ranges and other
ECO power supply conditions are met, the UPS works in bypass mode and the
inverter is in standby state. When the bypass voltage is outside the ECO voltage
range, the UPS transfers from bypass mode to normal mode. In bypass mode or
normal mode, the rectifier keeps working and charges batteries using a charger.
The ECO mode delivers a high efficiency.

2.4 Typical configurations

Table 2-18 Typical UPS configurations
Configuration Application Scenario

Single UPS Supplies power to common loads.

Dual-bus system The dual-bus system is suitable for scenarios where high
availability requirements are posed for power supply. The
dual-bus system supplies power to important loads in large-
and medium-sized equipment rooms and data centers.
In addition to common parallel system advantages, the dual-
bus system also provides outstanding availability and
eliminates bottleneck failures. However, configuration of the
dual-bus system is complex.

2.4.1 Single UPS

This series uses a modular design in which multiple power modules are connected
in parallel to deliver a high loading capacity. If a single power module is faulty, the
other power modules continue working. When the load power is small, even a
single UPS can provide redundant capacity, which ensures high reliability.

2.4.2 Single UPS Dual-Bus System

The dual-bus system consists of two independent UPS systems. One of the two
UPS systems is a master system, and the other is a slave system. This design
makes the dual-bus system highly reliable and suitable for loads with multiple
input terminals. An optional static transfer switch (STS) can be installed to start
the bus synchronization controller (BSC). The UPS systems work in normal mode
or bypass mode. The conceptual diagram uses a dual-bus system with a single
UPS as an example.

IP address allocation
● If the MDU is directly connected to a computer, the IP address can only be
allocated manually. The IP addresses of the MDU and computer must be in
the same network segment, and must be different.
● If the MDU is connected to a computer through a LAN switch or router with
the DHCP function, the IP address can be allocated manually or automatically.
Manual allocation is used by default.
– Manual: Check that their IP addresses are two different values on the
same network segment. Set the UPS IP address to be in the same subnet
as the PC IP address. Perform the bitwise AND operation for the UPS IP
address and the PC IP address with the subnet mask respectively. If the
operation results are the same, the two IP addresses are in the same
subnet.
AND operation rule: 1 AND 1 = 1, 1 AND 0 = 0, 0 AND 1 = 0, 0 AND 0 =
0. That is when the corresponding bits are both 1, the result is 1. In other
cases, the result is 0.

4.2.5 Protecting the Server by Using the RCCMD Software

4.2.5.1 Introduction to the Software

The RCCMD shutdown software is part of the centralized monitoring system of the
Generex network. The UPS5000 MDU integrates the functions of the Generex
RCCMD server:

● Sends the shutdown command, notification message, and Trap message to

the RCCMD client if the UPS system generates an alarm; executes commands
on the RCCMD client.
● Receives the message "UPS alive check" sent by the RCCMD client and replies
with the system status.
● Configures and saves the address and port for receiving the shutdown
command, and the message sending mechanism.

For the method of installing the RCCMD client, see the manual related to the
RCCMD.

Step 2 On the MDU WebUI, choose Config. > RCCMD, and set RCCMD function to
Enable.

Step 3 On the WebUI of the MDU, the SSL encryption is set to Enable by default and
does not need to be set. If the RCCMD client is set to the unencrypted mode, you
need to set the SSL encryption to Disable on the server WebUI.

Step 4 Configure events. If you set the job type to RCCMD Message under Inverter on,
specify the IP address and port of the RCCMD client. The port is 6003 by default. If
you need to modify the port, modify the port on the RCCMD client at the same
time to keep them the same. Enter the message to be sent and set the message
sending mechanism. For example, set it to Immediately, once.

Step 5 On the Monitoring > Control page, start the UPS, and the inverter mode will be
triggered. Send the message to the RCCMD client, indicating that the inverter is
on.

4.2.5.3 UPS Alive Check Function

Context

NOTICE

Whether the RCCMD SSL encrypted transmission is enabled on the WebUI of

UPS5000 MDU and RCCMD client is irrelevant to the heartbeat detection function.
Only when the SSL encryption is enabled on the RCCMD client, the logs recorded
by the RCCMD client are marked with "(SSL...)".

On the RCCMD client, the IP address of the MDU that detects heartbeat needs to
be added. Then the UPS alive check function is supported; the RCCMD can check
whether the UPS and RCCMD communicate properly; the RCCMD can receive
messages sent by the MDU.

Procedure
Step 1 On the RCCMD client, add the IP address of the MDU that detects heartbeat, as
shown in Figure 4-68.
Step 2 The UPS5000 MDU supports both ways of heartbeat detection. If the job
configured for the MDU event is set to RCCMD TRAP, the RCCMD client needs to
be set to by the use of CS121/UPSMAN Traps. If by polling CS121/UPSMAN
every x seconds... is selected as the method of detecting heartbeats, set the
detection method. The default interval is 1800s and detection is performed 100
times, as shown in Figure 4-68.

7 Troubleshooting

CAUTION

● If the UPS is faulty, alarm information is displayed on the LCD. Clear critical
alarms before powering on the UPS again. Otherwise, the fault scope expands
or the UPS is damaged.
● Do not clear alarms by reseating modules.
● Remove a faulty module after it is confirmed that the module needs replacing.
After removing the module, do not insert it into the UPS again.

NOTICE

● After a UPS finishes troubleshooting and is started, if the LCD continues

displaying alarm information, choose System Info > Alarms > Clear Faults to
clear the alarm and then start the inverter.
● When batteries reach EOD, the battery switch in the BCB box trips if the BCB
box is configured. To restore battery discharge, close the battery switch in the
BCB box (if any) first.
● To restore battery discharge after batteries reach EOD, use one of the following
methods: 1. Switch to another battery string. Ensure that each battery has a
voltage greater than the EOD voltage and 11.3 V/cell. 2. Restore the mains
power supply to start the inverter. Close the battery switch and charge batteries
until each battery has a voltage greater than the EOD voltage and 11.3 V/cell.

For details about how to rectify common faults, see Table 7-1. If any
unmentioned faults occur, see the alarm list chapter, or contact Huawei technical
support.
