EPO port

• A customer-supplied switch can remotely use to open the EPO connection and shut off UPS output. Since EPO shuts down the UPS immediately without regular procedure and monitoring, UPS will require a manual restart to restore operation.
• 3.3 Connection to External Battery Pack
  • External battery connections shall install by service personnel only.
  • Please read safety instructions first before proceeding.
  • Ensure UPS disconnects from all main and loads before attempting.
  • Locate the battery connector, then use only factory-supplied or authorized battery cable provided to connect the UPS with the battery as fig below.
  • Connect the second battery to the first one if more than one is needed.
  • The Maximum quantity of battery pack is regulated to 2 by UL approval.

Connection to Main and Load

• Follow all installation and safety instructions very carefully; failure to do so may cause hazardous situations to personnel and equipment.

• Ensure the main power voltage matches with UPS. (110V/220V)

• For electrical installation, closely observe the nominal current rating of the source.

• Check the equipment’s power requirement to prevent overloading situations.

• Do not connect devices that draw either massive power shortly or half-wave rectified current – such as hairdryer, vacuum cleaner, laser printer, and plotter.
  Note: Although you may use the UPS immediately, maximum back up time will not be available yet. It is recommended to charge the batteries for a minimum of 8 hours before use.

• Only a qualified technician with applicable safety standers may carry out the installation. Installation must also comply with local legislation and regulations.

• Connect the input cable to the UPS and the other end to the mains. The battery will automatically charge when connecting to the main power.

• Ensure the installation site has all electrical connections needed. Refer to the figure below for the fuse & cable dimension and connection diagram.

• To Isolate and secure the source against reclosing, both input and output circuit breakers (located in the back) must be “OFF.”

• After charging the UPS, connect the loads to the UPS.

• Should computer or alarm connections be used, refer to UPS monitoring connection chapter for further detail.

• Note: During installation, if whether the main power is grounded cannot be determined, or the main power’s neutral is unreliable, an additional two-pole disconnect device is necessary for building installation.

• Caution: Local safety requirements may demand separate external Emergency Power Off. Refer to External breaker/ EPO connection for further detail.

• The installation is completed.

Note: Wiring cord must be UL approved. (105°C).

External Breaker/External EPO connection

• Due to certain local safety requirements and legislation, you may require a separate external Emergency Power Off for output circuit breaker.
• If you need an external breaker for safety or maintenance reason, use the fig below for installation.

Operation

Necessary information for the operation of the unit is covered in this chapter. Normally UPS runs automatically, but on a few occasions such as just after installation, all procedures are described herein.

General Description

As double conversion On-line UPS, it can convert clean single-phase power to support your critical system. The diagram of UPS is as shown above

• Input filter reduces transients and interference from the main
• With PFC AC/DC, AC-power is rectified and regulated to DC power
• DC power is converted to AC in the inverter passing it on to the load

Line-Mode/Battery-Mode
UPS will operate in Line-Mode that supports power and charge battery while connected to power. During a power failure, the UPS will switch to Battery- Mode, in which power is maintained from the battery. In case of failure time exceed Battery-Mode duration, UPS will shut down until voltage return to prevent battery discharge.

Free Run Mode
Free Run Mode provides a wider input frequency range when input frequency does not match the selected range (user adjustable). Free Run Mode enlarges input frequency acceptance up to 45Hz ~ 65Hz but fixes output frequency to 50Hz(220V) and 60Hz(110V) with ±0.25Hz. Free Run Mode designs for large power variation. It is activated in default and can run with Line-mode simultaneously.

High-Efficiency Mode

• High-Efficiency Mode designs to minimize power loss and power consumption. Whenever power is stable, UPS will automatically switch to bypass for efficiency. When any irregularity is detected, Line-Mode will reactivate immediately. Switching occurs when the input voltage is outside ±10% of nominal (±15% selectable), input frequency is outside of ±3Hz, or when no input line is available.
• You can also activate this mode from the LCD panel. Refer to UPS configuration. Diagnostic Test
• The diagnostic test automatically executes to check and report UPS status. While the advanced battery management system monitors the conditions of the batteries, it sends early warnings if a battery replacement is needed. Diagnostic tests can also be performed by manual control.

Generator mode

• This mode designs for highly unstable power. In this mode, UPS normal operation will not transfer to bypass to prevent load damage and frequent battery discharge. UPS will also fix output frequency to 50Hz(220V) or 60Hz(110V) with ±0.25Hz. Users can set the UPS to bypass/shutdown whenever UPS malfunction occurred.
• Generator Mode can activate from the LCD panel too.

System Configuration
The UPS device and battery make up the system. Depending on site and load requirements, certain additional options are available as tailored solutions. Please consider the following when planning your UPS system:

• The total demand for the protected system shall dictate the output power rating (VA). When measuring demand, please allow a margin for future expansion and calculation error.
• Battery-mode duration needs dictate the battery size. If the load is less than the UPS nominal power rating, then the actual backup time is longer.
• The following options are available:
  • Connectivity options (relay card, SNMP/WEB card)
  • External battery packs
  • Transformer cabinets
  • Maintenance bypass switches
