Connecting the ERM to the UPS  
Configuring the UPS  
After the ERMs are installed, place the UPS in Configure  
mode, and use the UPS front panel controls and LED  
indicators to configure the UPS for the number of attached  
ERMs. Other UPS parameters that can also be configured  
are the nominal utility voltage level and Site Wiring  
Fault detection.  
In Configure mode, the LED front panel display changes  
function to enable modification of the UPS parameters. Each  
LED is associated with a different parameter.

Charging the ERM batteries  
Connect the UPS to a grounded utility power outlet. When the  
UPS is plugged in, it automatically enters Standby mode and  
begins charging the ERM batteries. With the UPS in Standby  
mode, allow the ERM batteries to charge for at least 24 hours  
before putting the UPS into service.  
To change the UPS configuration parameters:  
1. Place the UPS in Configure mode.  
The LEDs associated with the currently configured  
parameters illuminate. A flashing green cursor indicates  
where you are in the configuration process as you scroll  
through the available settings.  
CAUTION: To ensure maximum runtime, be sure to  
configure the UPS for the number of installed ERMs  
using the UPS front panel controls.  
2. To change the nominal voltage, press the On button to  
advance the cursor to the LED associated with the  
appropriate nominal voltage parameter. The selected  
voltage configuration LED flashes.

3. Press the Standby button to select the nominal voltage  
configuration. The LED associated with the old input  
voltage parameter turns off, and the LED associated with  
the new input voltage parameter illuminates solid green.  
UPS front panel LED indicators  
NOTE: Only one nominal utility voltage can be  
configured. When setting voltage configuration  
parameters, selecting an On value for any one  
parameter automatically sets the other possibilities  
to Off.  
4. To enable the Wiring Fault parameter, press the On  
button to advance the cursor to the Utility LED, then press  
the Standby button. The LED illuminates solid green.  
This parameter is disabled by default, and should only  
be enabled for line-to-neutral connections. Enabling this  
feature for line-to-line power sources causes a  
false alarm.  
The front panel is shown with the bezel removed.  
5. To configure the UPS for the number of connected ERMs,  
press the On button to advance the cursor to the load  
LED associated with the number of ERMs attached to  
the UPS.
