If the Rectifier input is within voltage range, the rectifier will start up in 30 seconds then
the inverter will start up after then.
If the rectifier fails at startup, the bypass LED will light up. When the inverter starts up,
the UPS will transfer from bypass mode to inverter mode, then the bypass LED
extinguishes and the inverter LED lights up.
No matter whether the UPS can work normally or not, all the status will be shown on the
LCD display.
4.2.2 Test procedure

Switch off the MAINS to simulate utility failure, the rectifier will turn off and the battery
should feed the inverter without interruption. At this time, the LEDs of battery should be turned
on.
◆
Switch on the MAINS to simulate utility recovery, the rectifier will restart automatically
after 20 seconds and the inverter will supply to the load. It is suggested to use Dummy loads
for testing. The UPS can be loaded up to its maximum capacity during load test
。
4.2.3 MAINTENANCE BYPASS
