Bryant Liquid-cooled 15 kW Generators

1.1GENERATOR

This equipment is a liquid-cooled, engine-driven gen- erator set. The generator is designed to supply elec- trical power that operates critical electrical loads during utility power failure. The unit has been facto- ry-installed in a weather resistant, all metal enclosure and is intended for outdoor installation only. Use this generator as a source of electrical power for the oper- ation of 120 and/or 240 volts, single phase loads.

These models are available. They are rated as follows:

Model ASPAS1BBL015: 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 Bryant 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 preset 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 re-transfers back to the utility source voltage and the generator then shuts down.

Please reference the transfer switch manual for spe- cific information.

1.4GENERATOR AC CONNECTION

SYSTEMS

The generator was shipped from the factory with its stator AC output leads connected in a single-phase, three-wire generator AC connection system (Figure 1.1). The stator assembly in this system consists of a pair of stationary windings, with two leads brought out of each winding. Each single winding can supply 120 volts AC, 60 Hertz. When the two windings are connected in series, a 240 volts, 60 Hertz AC output results. Typically the two “hot” leads in the circuit are Wires No. 11 and 44. The “Neutral” leads are the junction of Wires 22 and 33.
