This equipment is a
These models are available. They are rated as follows:
Model ASPAS1CCL015: Provides 15,000 watts (15 kW) of single phase power.
If this generator is used to power electrical
!load circuits normally powered by a utility power source, it is required by code to install a transfer switch. The transfer switch must effectively isolate the electric system from the utility distribution system when the generator is operating (NEC 701). Failure to isolate an electrical system by such means results in damage to the generator and may also result in injury or even death to utility power work- ers due to backfeed of electrical energy.
1.2TRANSFER SWITCH
This generator system includes a matched automatic transfer switch which is intended to be used in con- junction with the generator. It is supplied with a NEMA 3R enclosure. The NEMA 3R enclosure is weather proof and can be used indoors or outdoors. Follow these rules:
•Install the transfer switch on a firm, sturdy sup- porting structure.
•To prevent switch distortion, level the switch if nec- essary. This can be done by placing washers between the switch enclosure and the mounting surface.
•Never install the switch where water or any corro- sive substance might drip onto the enclosure.
•Protect the switch at all times against excessive moisture, dust, dirt, lint, construction grit and cor- rosive vapors.
•Failure to utilize a Carrier transfer switch with this generator will void the warranty.
1.3AUTOMATIC SYSTEM OPERATION
When this generator, along with its transfer switch, has been installed and interconnected, a circuit board in the generator panel constantly monitors utility power source voltage. Should that voltage drop below a pre- set value, and remain at such a low state for a preset amount of time, the generator cranks and starts. After the generator starts, the transfer switch transfers load circuits so the generator can power them.
When utility source voltage has been restored, the switch
Please reference the transfer switch manual for spe- cific information.
