Fig. 6.1.2-1 LCD screen

UPS model

Date (format “MM/DD/YYYY”).

Time AM or PM (format “HH.MM.SS”). eBoost (green color)

LED ON/lit indicates that the UPS is operating in eBoost™ mode.

IEMi (green color)

LED ON/lit indicates that the UPS is operating in IEMi mode.

Service Key (yellow color)

Key for disabling the Service Key procedure.

Used only by the ABB Service Center.

LEDS UPS STATUS

LED LOAD PROTECTED (green color)

When lit, indicates that the UPS is functioning correctly and the Load is system protected (Load supplied either from Inverter or from Automatic Bypass in case of eBoost™ Operation Mode).

When blinking, indicates that a regular maintenance service is needed (SERVICE REQUIRED).

May be reset by an ABB Service Technician only.

See Section 9 – Maintenance – Service check.

The LED is OFF when the “Q1 – UPS output switch” is open, indicating that the Inverter is in service mode, not supplying the Load.
