7. Attention of battery disposal
◇
Please take off metal objects, such as, ring, watch and the likes before dealing with batteries.
◇
If you want to replace the battery cable, please purchase it from our local service center or distributors to
avoid fever and lighter which can cause fire from inadequate power capacity.
◇
Don’t dispose the battery or battery pack by fire, it will explode.
◇
Don’t damage or open the battery case, the overflow battery electrolyte has a strong toxicity which will do
harm to humans.
◇
Please avoid short circuit which may cause fire or electric shock.
◇
Please check the battery voltage before touching. Otherwise, it will form a high voltage environment
between BAT. There will be high voltage between the terminals and the ground when battery circuits and
the input voltage loop is not isolated.
8. Network communication
This series UPS offer intelligent network interface with a dedicated Ethernet card (optional accessory), to
realize network communications. For more details, please contact our local distributor or service center.
9. Communication interface introduction
The UPS communicates with PC via analog relay joint and serial interface (RS232). The former transmits the
input power and UPS status to PC by choosing “on” or “off” states of transistor. The latter offers
communication interface serials with PC to monitor input power and UPS status information, and control the
UPS also.
Note:
The communicating function is only realizable with the specific communicating cable from the supplier.
RS232 interface is set as below:
