STATUS WARNING !
RECTIFIER START :
At start up the UPS controller board check for input voltage, frequency, battery voltage for starting, if these
parameters normal UPS starts.
INVERTER START :
If the inverter stops controller board tries to start again, during inverter start this message appears on first line of
LCD PANEL.
MAINT SWITCH ON:
Maintenance bypass switch is connected from input to the output of UPS directly, controller stops inverter for
accidental short circuits between mains voltage and inverter output. If the user turn off maintenance switch
inverter starts again.
EMERGENCY STOP :
If an external EPO switch is installed to system (connected to interface board),to stop all UPS parts
(rectifier,static bypass,inverter,etc....) is possible. After pressing EPO switch all parts of the UPS stops,for
restart turn off S1 (inverter input) switch and turn on again.
