T
he transfer switch control board has active circuits sensing utility
and generator voltages. It creates a signal for generator start-up,
switch transfer and retransfer when utility is restored. The transfer
switch control board provides status LED’s to indicate the power
source available.
The Symphony® II power management system control board
contains a test button, a status LED and eight priority load LED’s. It
creates and sends signals to optional remote modules, instructing
them when to add (turn power on) or shed (turn power off) the
managed load.
The Symphony® II system power line carrier technology has been
rigorously tested and has proven to be very robust. However,
certain types of devices and appliances in the home generate
‘noise’ on the power line. Such devices may include non-residential
fluorescent ballasts, dimmers, speed controls (lighting and fans),
bathroom equipment, kitchen equipment, power tools, phone
chargers, and power supplies. These types of devices have the
greatest impact on power line communication when located close
to a remote module.
AM broadcast radio, X10, power line carrier (PLC), uninterrupted
power supply (UPS), transient voltage surge suppression
(TVSS) systems, and power filter technology may also cause the
Symphony® II system to not operate as intended. They may cause
interference with the Symphony® II system during standby power
operation.
If it is determined that power line noise is causing a communication
issue with the Symphony® II system, the following changes may
remedy the issue.
• Have commercial (non consumer use) fluorescent ballasts
replaced with residential use ballasts.
• Have a EMI/RFI filter installed in series and near the
problematic device.
• Have the remote module rewired to the opposite power line
(Line 1 or Line 2) from that of the problematic device.
• Refer to Troubleshooting section.
The optional 50 Amp remote module is designed for control by the
Symphony® II system to add or shed appliance loads connected
to it based on a user-defined priority setting. This remote module
manages 120VAC or 240VAC, single or double pole loads up to
50 amperes. The remote module’s relay state is normally open. Its
components are housed in a NEMA 4 enclosure suitable for indoor
and outdoor installations.
The optional low voltage remote module is designed for control by
the Symphony® II system to add or shed an air conditioner, heat
pump, or low voltage contactor controlled loads based on a user-
defined priority setting. The remote module is housed in a NEMA 4
enclosure suitable for indoor and outdoor installations.
Delivery Inspection
After opening the carton, carefully inspect the transfer
switch components for any damage that may have occurred
during shipment.
If loss or damage is noted at time of delivery, have the person(s)
making delivery note all damage on the freight bill and affix his
signature under the consignor’s memo of loss or damage. If loss
or damage is noted after delivery, contact the carrier for claim
procedures. Missing or damaged parts are not warranted.

Mounting Guidelines
The transfer switch system circuitry is enclosed in a NEMA Type 3R
enclosure suitable for indoor/outdoor use. Guidelines for mounting
the enclosure include:
• Install enclosure on a firm, sturdy supporting structure.
• The transfer switch enclosure must be installed with
minimum NEMA 3R hardware for conduit connections.
• To prevent switch contact distortion, level and plumb the
enclosure. This can be done by placing washers between the
enclosure and the mounting surface.
• NEVER install the switch or remote modules where any
corrosive substance might drip onto the enclosure.
• Protect the switch at all times against excessive moisture,
dust, dirt, lint, construction grit and corrosive vapors.
A typical automatic transfer switch installation is depicted on
the next page. Examples of remote module installations are also
shown. It is best if the transfer switch is mounted near the utility
meter, either inside or outside. The remote module can be located
anywhere between the main distribution panel and its connected
load, either inside or outside. The remote module must be
accessible for service. Discuss layout suggestions/ changes with
the owner before beginning the system installation process
NOTICE Before drilling conduit entry holes, or any other holes,
cover and protect the switch and electronics to prevent dirt and
metal fragments from entering the mechanical and electrical
components. Failure to do so may result in damage or malfunction
of the switch.
NOTICE Use a vacuum to clean any dirt or metal shavings inside
the transfer switch. Do not use a blower or compressed air to clean
the inside of the transfer switch because debris may become lodged
in the electrical and mechanical components causing damage or
malfunction.
