installed in the UPS frame (IntelliSlot Port #3, typically).
• If it is not installed, obtain the EBC communication card and insert it into any open
IntelliSlot port (preferably Port #3).
• Connect the provided EBC communication cable to the UPS and EBC as shown in Figure
3.25 below or Figure 3.26 on the next page, depending on your system.
7. Check the EBC DIP-switch settings on the top rear of each EBC frame, and verify that they are
set correctly according to Table 3.12 on page 47.
7. Close the EBC DC circuit breaker and replace the bezels back onto the EBC.
WARNING! Risk of hazardous voltage between UPS frames. Can cause damage to equipment,
injury and death. Failure to open the EBC DC circuit breaker before connecting or
disconnecting the battery cable between the UPS and EBC frames can result in hazardous
voltages being present between the frames.
