The 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 All wiring must be the proper gauge, properly
supported and protected by conduit. All wiring should be
done per applicable federal, state and local codes, standards
and regulations. Obey wire type and torque specifications
printed on the terminal blocks, neutral/ground connectors,
and installation instructions. Approved for copper and
aluminum conductors.
