6.1 Usage announcements
• Before starting the UPS, check whether the load is proper. The load must not exceed the rated output power
of the UPS, to avoid overload protection.
• Do not use the <ON> and <OFF> buttons on the UPS panel as the power supply switches of load.
Do not restart the UPS frequently.
• Once the UPS starts and works smoothly, turn on the load. Start big-power devices before small-power
ones. Some devices have large starting current which may cause overload protection, it is better to start
these before others. If the UPS needs to be shut down, turn off the load first.
• When mains power outage, if the UPS is power supplied by generator, it is necessary to start the generator
first. Once the generator works smoothly, the UPS can be connected, else it may result in damage to UPS
or load. If the generator needs to be shut down, turn off the UPS first.
6.2 Operating procedure
Before starting the UPS first, it is necessary to do the mandatory checks. Only when the pass test is cleared,
the UPS can be powered on. Even if the UPS will not be used for a long time, a check need to be performed
before start up. Operation procedure is as shown in Figure 6-1.
