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.
Shipment contents:

• Current transformers (2)
Optional components:
• 50 Amp module
• Low voltage module (single or dual models)
• Symphony™ II power monitor
To be supplied by installer:

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.
