Basic Parameter Settings
Single/Parallel, Output voltage level and Output frequency, as well as Battery capacity
and Number of cells must be the same as the actual values. Otherwise, an alarm may be
generated, or other serious faults may occur.
Set basic system and battery parameters, as shown in
Issue 06 (2019-12-13)
NAT Mapping
NAT means network address translation. If it is set to Disable, an internal IP address
cannot be accessed from the Internet.
RS485 baud rate/RS485 address
Set an address that ranges from 1 to 254 for this port. Baud rate depends on the network
management conditions.
Parity mode
Verify the validity of RS485 communication characters. When a device node adopts
RS485 communication, ensure that the parity modes for the device nodes are set to the
same mode. Available parity modes include None, Odd, and Even.
Stop bit
When the UPS is connected over the serial port Modbus, set this parameter based on the
frame format that the upstream device Modbus supports (the Modbus communication
frame format uses a binary digit).
Batt. temp. sensors
A maximum of four battery temperature sensors can be cascaded.
Start addr. of batt. temp. sensor
Set this parameter by using the DIP switch on the battery temperature sensor. The
address range is 16–28. Ensure that the address set on the LCD is the same as that set for
the DIP switch. Otherwise, communication fails.
BMUs
A maximum of 12 BMUs can be cascaded.
BMU start address
Use the DIP switch on the BMU to set the BMU start address to 112. Ensure that the
address set on the LCD is the same as that set for the DIP switch. Otherwise,
communication cannot be implemented.
Amb. temp & humid sensors/Start addr. of amb. temp. & hum. sensors
An ambient temperature and humidity sensor has the same appearance as a battery
temperature sensor. The two types of sensors can be cascaded (up to four). The ambient
temperature and humidity sensor address range is 32–44, which is different from the
battery temperature sensor. Therefore, you can use the sensor as an ambient temperature
and humidity sensor or battery temperature sensor by setting the address.
NTC
The short-distance battery temperature sensor monitors the ambient temperature near
batteries, and ensures that batteries work reliably and securely. The default status is
Disable. If a short-distance battery temperature sensor is configured, set NTC to Enable.
