Next, turn ON the power of the load devices.

Check that the LCD display and LEDs are in the states shown in the figure below.
*1.
If “
CONTROL NG” is displayed, the UPS cannot be started because there is an input power supply error or the like.
Check the status of
“
STATUS” in the home menu of the LCD panel and see
“
§11. Troubleshooting.”
*2. Load capacity
If
“
OVER LOAD” is displayed on the LCD screen and a beep-beep-beep-beep beep-beep-beep-beep buzzer sound can be
heard when the power of the load devices is turned
“
ON,” the load devices connected to the UPS exceed the rated capacity
of the UPS. Reduce the number of connected load devices.
If this state persists even after reducing the load devices to the UPS rated capacity or less, check that all of the
unit-to-unit output cables on the back of the UPS Units are connected properly. If there is a UPS unit without a cable
connected, the total capacity will be reduced by an amount equivalent to the capacity of that UPS unit, and an overload
state will occur even at a load capacity that is not above the UPS rated capacity.
See
“
§6.3.1 Wiring Between UPS Units,” and connect it correctly.
