Reliance Controls PowerBack THP108 Instructions

INSTRUCTIONS FOR THE RELIANCE
PowerBack
Model THP108
Non-Contact Utility Power Return Alert
THE RELIANCE PowerBACK IS NOT FOR "DO-IT-
YOURSELF" INSTALLATION. It must be installed by a
qualified electrician in accordance with all applicable
electrical and building codes.
This Reliance PowerBACK is a non-contact utility power return
sensor with audible alert. If the main circuit breaker in a generator-
ready load center or manual transfer panel, has to be turned the
OFF position in order for the standby generator to supply power to
the circuits within the panel, the PowerBACK, when activated, will
sound a 100dB audible alert when utility power is restored.
The Reliance PowerBACK! will indicate that utility power has
returned and the standby generator may be shut down.
KEY COMPONENTS OF
RETURN ALERT
1. Audible alert and battery enclosure with "System Armed" and
"Low Battery" lights.
2. 23" flexible insulated cable attached to a 15" flexible current–
sensing antenna.
3. A 36" ground wire
INSTALLATION
CAUTION! The PowerBACK! is an isolated low-voltage device
that is intended to come in contact with insulated conductors
feeding a residential or light commercial load center (circuit
breaker panel). It is not intended for use on uninsulated
conductors such as busbars
DANGER! HAZARDOUS VOLTAGE! TURN MAIN CIRCUIT
BREAKER TO THE OFF POSITION BEFORE INSTALLATION.
DANGER! THE LINE TERMINALS ON THE MAIN CIRCUIT
BREAKER MAY BE LIVE
PROCESS. TAKE ALL APPROPRIATE SAFETY MEASURES
DURNG INSTALLATION.
INSTALLERS CONTACT THE LOCAL POWER UTILITY TO
DEENERGIZE THE LOAD CENTER BEFORE INSTALLING THE
PowerBACK.

THE PowerBack POWER
DURING THE INSTALLATION
IT IS RECOMMENDED THAT
1. Install a fresh 9V alkaline
battery in the PowerBACK
battery compartment..
2. Move Main (Utility) circuit
breaker handle to the "OFF"
position.
3.Remove panel cover.
4. Locate and remove a ½"
knockout within 20 inches of
the incoming utility power
conductors.
5. Remove the retaining nut
from the PowerBACK
threaded nipple.
6. Feed the flexible cable (the
black part) and antenna (the
white part) through
knockout from the
outside.
7. Feed the flexible cable
and antenna through the
retaining nut.
8. Fasten the PowerBACK
to the enclosure with the
retaining nut.
9. Carefully wrap the 15-inch flexible antenna in a tight coil around
one of the main power cables feeding the main circuit breaker. The
antenna should be secured in the tight coil with electrical tape or a
cable tie as shown in the photo. DANGER! IF THEY HAVE NOT
BEEN DEENERGIZED, THE LINE TERMINALS ON THE MAIN
CIRCUIT BREAKER WILL BE LIVE DURING THE INSTALLATION
PROCESS.
10. Strip the ground (green) wire and connect it to the ground bus in
the loadcenter.
11. Replace panel cover, turn the main circuit breaker ON, and
reenergize the loadcenter.
TESTING
1. Simply turn the PowerBACK on/off switch to the ON position.
The 100dB alert will sound.
2. Return the Power BACK on/off switch to the OFF position.
The red "Low Battery Indicator" will light when the battery needs to
be replaced.
OPERATION
1. When utility power fails, turn the PowerBACK on/off switch to the
ON position. The green "System Armed" light will come on.
2. Follow the instructions on the generator-ready load center or
manual transfer panel for activating the link to the standby power
system.
3. When utility power is available to the panel, the PowerBACK will
emit a 100dB audible signal.
4. Turn the PowerBACK on/off switch to the OFF position.
5. Follow the instructions on the generator-ready load center of
manual transfer panel to return utility power.
TROUBLESHOOTING
1. PowerBACK will not sound alert when utility mains power is
available
a. Replace 9v battery with known good battery.
b. Assure that the sensing antenna is wound tightly around the main
feeder cable. Reposition sensing antenna if necessary.
2. PowerBACK alerts when loadcenter is being supplied by
generator power.
a. Assure that the ground wire is properly connected.
b. Assure that the sensing antenna (the white part) is not near any
conductors that are energized by the generator
c. Re-route the flexible cable (the black part) as far away as
possible from any conductors that are energized by the
generator.
CAUTION: Do not operate any generator in an enclosed
area, where the exhaust fumes can accumulate in an
enclosed area, or near open doors and windows
