Connecting the Telephone/Modem/Ethernet Lines 
Connect a telephone line, modem line, or 10BaseT line into the telephone/modem/Ethernet surge 
protection sockets on the back of the UPS. The RJ-45/RJ-11 modular sockets accept standard 
single line telephone connections and 10BaseT connectors.  This connection will require another 
length cable. 
 
Note: This connection is optional. It is not necessary to use this with the UPS. 
 
Caution: The line current limiting feature could be rendered inoperable if improperly 
installed.  Make sure that the line from the wall is plugged into the connector marked “IN”, 
and the device to be protected (telephone, modem, etc.) is plugged into the connector 
marked “OUT”.  
 
Caution: This surge protection device is for indoor use only, never install wiring during a 
lightning storm. 
 
Check the Site Wiring Fault Indicator 
After plugging in the load(s) and the UPS, check the site wiring fault indicator on the rear panel.  
It lights up if the UPS is plugged into an improperly wired AC power outlet.  Wiring faults 
detected include ground, hot-neutral polarity reversal, and overloaded neutral circuit.
