(a)MCU detects the status of EPO button (on LCD display panel) via “EPO” (85) (low active). When the EPO button is activated, UPS will shut down the output and turn off the inverter. When the EPO button is released, UPS will stay in bypass mode.

(b)MCU can control the LCD backlight via “U-lcmBL” (62).

(c)MCU can adjust the contrast of LCD by PWM control via “U-lcmCA” (2).
