Troubleshooting
Fault: The UF-RS485 output signal does not change with the UPS status.
Action to take: Ensure that the UF-RS485 card is properly inserted into the Intellislot port and the cable is
properly connected.
7.1.3. Installation Procedures
WARNING! Some electron components in the intelligent card are sensitive to static, therefore,
do not touch the electron components or circuit in the intelligent card by hand or other
conductive materials, so as to protect the intelligent card against static shock. When removing
or installing the intelligent card, hold the card side edge to operate it.
1. Remove the protective cover on the UPS intelligent card, retain the screws, and keep the protective
cover properly for future use.
2. Insert the intelligent card (along two sides of the Intellislot port) into the port position recommended in
Figure 7-1 , and then fasten the screws.
NOTE: 1. SIC card, UNITY-DP card, UNITY-LIFE card, and IS-RELAY card can be installed at Intellislot1
or Intellislot2.
2. When installing the UNITY-DP card or the UNITY-LIFE card at Intellislot1 or Intellislot2, if you wish to
change the baud rate, just change the ‘serial port 2 baudrate’ on the operator and display panel.
3. When installing the SIC card at Intellislot2, if you wish to change baud rate, just change the ‘serial
port 2 baudrate’ on the operator and display panel.
4. When installing the SIC card at Intellislot1, if you wish to change the baud rate, you first need to
confirm the current communication mode of SIC card is RS232 or RS485 via the SIC card web interface.
If RS232 communication mode, it can be realized by changing ‘serial port 1 baudrate’ on the operator
and display panel; if RS485, it can be realized by changing ‘serial port 2 baudrate’ on the operator and
display panel.
5. The path of ‘serial port 1 baudrate’ and ‘serial port 2 baudrate’ on the operator and display panel is:
main menu screen -> setting -> monitor -> serial port 1 baudrate or serial port 2 baudrate.
6. The path of main menu screen -> setting -> monitor ->UPS address is used to set the communication
address of this UPS through the YDN23 protocol.
7. The path of main menu screen -> setting -> monitor -> card slot protocol is used to set the RS485
bus protocol in the two intelligent card ports, and the protocol used is YDN23 or Velocity. The SIC card
adopts YDN23 protocol while UNITY-DP card and UNITY-LIFE card adopt Velocity protocol.
IMPORTANT!These procedures shall only be carried out by service personnel of Vertiv or under
their guidance.
