1.3.4 Auto Restart Mode

When enabled, which is the default setting, Auto Restart Mode automatically restarts the UPS after a shutdown that resulted from depleted batteries after an extended power outage. A built-in 10-second delay after utility power is restored allows other equipment to start first and stabilize before the UPS restarts.

1.3.5 Fault State

When the UPS is in Normal Mode and the inverter fails or UPS overtemperature occurs, operation transfers to Bypass Mode. When the UPS is in Battery Mode (with no bypass utility), and the inverter fails or overtemperature occurs, the UPS shuts down and stops output power. During a fault state, the front panel display alarm indicator (red)is On, the buzzer beeps continuously, and fault information displays on the LCD.

1.3.6 Maintenance Bypass Mode

Used when the UPS requires maintenance or repair, Maintenance Bypass Mode operation powers the connected equipment with utility power while electrically isolating the internal UPS components.

The optional Liebert® ITA2 Maintenance Bypass Cabinet (MBC) is required for this mode. If your system includes a Liebert ITA2 MBC, refer to the Liebert ITA2 MBC Installer/User Guide, available on the product page at www.Vertiv.com.

NOTICE

Risk of power interruption. Can damage the connected equipment.

If utility power fails or if its quality is out of range while the UPS is in Maintenance Bypass Mode, the UPS may shut down without notice and shut off output power to the load.

NOTE: The UPS has no user-serviceable parts. If the UPS malfunctions and requires service, visit http://www.Vertiv.com/en-us/support/ or contact your local Vertiv™ representative.

1.3.7 Start up on Bypass Mode

Default : Disabled. When the inverter is in the soft start stage, the bypass mode will not be automatically triggered.

Change the startup on bypass via Paramset or the LCD settings page to enable.

When the DC bus soft start is completed, the bypass mode will be automatically triggered. If the inverter can enter the soft start stage and the soft start is completed, the ups will automatically switch from bypass mode to normal mode.

When the DC bus soft start is completed, the bypass mode will be automatically triggered. If the inverter can not automatically enter the soft start phase, the ups will always operate in the bypass mode.

2.1.4 Storage

If you do not install the UPSimmediately, you must store it indoors and protect it from excessive moisture, heat and other harsh conditions. Store the batteries in a dry, well-ventilated environment with a temperature range of 68°F ~ 77°F (20°C ~ 25°C).

NOTICE

Risk of failure to properly charge batteries. Can damage the batteries and void the warranty.

Batteries will lose charge during storage. Batteries must be recharged as recommended by the battery manufacturer every 3 to 6 months, depending on the storage temperature:

• At 68-77°F (20-25°C): charge after 6 months in storage

• At 78-86°F (26-30°C): charge after 3 months in storage

• At 87°F or higher (31°C or higher): charge after 1 month in storage.

2.1.5 External Protective Devices

Circuit breakers and other external protective devices must be installed on the UPS input. The following sections provide general guidance for installation by properly trained and qualified personnel.

Rectifier and Bypass Input Protection

Overcurrent Protection—Install an appropriate overcurrent protective device should on the utility input power distribution. Consider the current capacity of power cables and the system-overload requirements in selection of the input protection and wiring, see Table 2.1 on page18 , and Table 2.2 on page19 .

Dual-Input System Protection—In a dual-input system, install separate protective devices for the utility and bypass at the utility input power distribution.

Utility/Bypass Back-Feed Protection—The UPS includes back-feed protection in the event of a fault.

Earth Leakage Current—The residual current detector (RCD) for the UPS upstream input power distribution should be:

• Sensitive to the DC unidirectional pulse (Level A) in the power distribution network

• Insensitive to the transient current pulse

• General sensitivity type, settable: 0.3A ~ 1A

The residual current circuit breaker (RCCB) must be sensitive to the DC unidirectional pulse (Level A) in the power distribution network, but insensitive to the transient current pulse, see Figure 2.2 below .

Figure 2.2 RCCB symbols

2 In stallation

When using the earth RCD in a split-bypass system, the RCD should be installed at the upstream input power distribution end to prevent false alarms.The earth leakage current fed by the RFI filter in the UPS ranges from 3.5mAto100mA. Vertiv™ recommends that you verify the sensitivity of each differential device of the upstream input power distribution and downstream power distribution (to load).
