Normal boot process due to the general load at startup instant impact current, and power UPS internal components have a safe working area range, although we when choosing device has the certain allowance, but the impact of excessive current will shorten the service life of components, even damaged components, so when use to minimize the impact brought by the current damage. General UPS - ESIA series RM type 2-3 kva rack type work in bypass is impact resistant ability is stronger, we can use this feature in the boot in the following ways, first send UPS, mains in bypass, in open each load, opening shock current larger load first, then opening shock smaller load current, and then the UPS panel boot, make its in the inverter working state. Don't put all the load when the phone is switched on at the same time open, and do not load boot.

 

Shut down the order

Shutdown sequence is as follows, shutting down the load first, and then turn off the UPS panel, make UPS bypass work and chargers continue recharging the battery, if you don't need to UPS output, UPS will be shut down completely, the input mains disconnect again can.

The use of UPS backup type

Backup type UPS in the mains under normal circumstances, to bypass the power supply, only depends on the input fuse protection, such as users do not pay attention to when using it, and the overload use, although the utility condition UPS still can continue to work, but when the mains turn abnormal cell inverter is working, will be shut down because of overload protection. Caused serious damage of UPS, the above situation will be led to the suspension of the output, bring some losses to the user. So should pay special attention to when using a backup UPS do not overload use.
