Emerson 208 Manuel D’Utilisation

The following is a general description of each compo-

nent and its functions. Please review this section 

carefully, as it will give you a better understanding as 

to how the Nfinity operates.

The front of the Nfinity consists of a series of plastic 

bezels. By grasping these bezels from the left and 

right sides and pulling straight out, you can remove 

the bezel to reveal the Battery / Power Module bays. 

The bottom bezel covers the internal cooling fans and 

the manual bypass switch.
The User Interface Module is located above the 

Power / Battery Module bays for easy access. By mov-

ing the User Interface and setting it on top of the 

frame, you will see the system control module bays.

The User Interface Module is the primary source of 

communication between the UPS and the user. From 

the interface, the user can:

• View the status of the UPS
• Custom configure the system
• Review the event log to assist with 

troubleshooting

• Enable/disable the output power
• Silence the audible alarm
• Manually transfer the unit to bypass

For a more detailed explanation on how to operate the 

User Interface Module, see 3.1 - Controls and Indi-

cators.

The System Control Module is the communications 

backbone of the UPS. It gathers input from all mod-

ules and processes the data to control the operation of 

the system — including monitoring the condition of 

each module. An optional redundant System Control 

Module can be installed to provide full system func-

tionality (operation and communication).
Under normal operation, the Status LED (green) will 

blink and the Fault LED (yellow) will be off. For any 

condition other than this, check 4.0 - Troubleshoot-
