Supervisory Control Terminals
To avoid undesirable operation, we recommend loads be managed only with low voltage or 50 Amp remote modules. Do not use the transfer switch control board supervisory control terminals (if present).
The illustration on the following page shows a completed transfer switch installation. Your actual layout will vary. Illustration callouts are:
A - From utility watt-hour meter B - Current transformers
C - Transfer switch
D - Symphony™ II system control board E - T/R and GND to Generator
F - Transfer switch control board

12. Connect conductor from transfer switch neutral terminal to generator NEUTRAL terminal. Observe generator control panel labeling for terminal identification.

13. Connect conductor from transfer switch “GND” terminal to generator control panel “GROUND” terminal.

Assure generator equipment grounding conductor is connected per applicable federal, state and local codes, standards and regulations.

Controls

Other than a Manual Override lever, there are no operator controls because this is an automatic transfer switch. The manual override is to be used only by licensed professionals. Information on handle use can be obtained by calling Technical Service at 800-743-4115.

Operation

To select automatic transfer operation, do the following:

1.In transfer switch, set utility disconnect circuit breaker to “ON” position.

2.In transfer switch, set generator disconnect circuit breaker to “ON” position.

3.Install 15 Amp fuse in generator’s control panel.

Symphony™ II Power Monitor (Optional)

For your convenience, a Symphony II Power Monitor is available, which provides a visual “on/off” status of each managed appliance/load. A series of LED lights are ON when an appliance has generator power and OFF when the appliance is in a shed mode or does not have power. When on generator power, the consumer can see which appliances are being managed.

A decal is provided that can be labeled with the managed appliances/loads and placed next to each priority LED.

The monitor is plugged into any convenient standard outlet within the home and constantly receives system status via the power line communication technology utilized by the Symphony II Power Management System during generator power.
