Surge Protection
Surge Protection
The Back-UPS protects equipment connected to a 10/100 Base-T ethernet, from
power surges when connected through the Back-UPS coaxial connectors.
Turn On the Back-UPS
Press the POWER ON button located on the top of the Back-UPS. The Power On/
Replace Battery LED will illuminate and a single short beep will be audible to
indicate that the Back-UPS is providing protection for connected equipment.
The Back-UPS is shipped with one battery cable disconnected. Remove the “Stop!
Connect the Battery” label that covers the outlets. Prior to connecting any equipment
to the unit, connect the battery cable to the unused battery terminal. It is normal for
small sparks to be seen when the battery cable is connected to the battery terminal.
The Back-UPS battery charges fully during the first 16 hours while connected to
utility power. The Back-UPS battery will charge while the Back-UPS is switched on
or off and is connected to utility power. Do not expect full battery run capability
during the initial charge time.
 Press the battery compartment cover
release tab located on the rear side of the
unit. Slide the battery cover off.
If the red Building Wiring Fault LED located on the side of the Back-UPS
illuminates, do not operate the Back-UPS. Have a qualified electrician correct the
building wiring fault.
Voltage Sensitivity Adjustment (optional)
The Back-UPS detects and reacts to line voltage distortions by transferring to battery
backup power to protect connected equipment. In situations where either the BackUPS or the connected equipment is too sensitive for the input voltage level it is
necessary to adjust the transfer voltage.
 Connect the battery cable securely to
the battery terminal.
1. Connect the Back-UPS to a wall outlet. The Back-UPS will be in Standby mode,
no indicators will be illuminated.
2. Press and hold the ON/OFF button for 10 seconds. The OnLine LED will
illuminate alternately green-amber-red, to indicate that the Back-UPS is in
Program mode.
3. The Power On/Replace Battery LED will flash either green, amber, or red to
indicate the current sensitivity level. Refer to the table for an explanation of the
transfer voltage sensitivity levels.
 Reinstall the battery compartment
cover. Be sure that the release tab locks
into place.
4. To select LOW sensitivity, press and hold the ON/OFF button until the LED
flashes green.
5. To select MEDIUM sensitivity, press and hold the ON/OFF button until the LED
flashes red.
6. To select HIGH sensitivity, press and hold the ON/OFF button until the LED
flashes amber.
Wall Mount Installation
Horizontal installation, use 2 screws 5.0" (127 mm) apart.
Vertical installation, use 2 screws 4.3" (110.4 mm) apart.
Allow 5/16" (8 mm), of the screw to protrude from the wall.
