Guardian Liquid-cooled 15 kW, 20 kW and 25 kW Generators

NOTE:

For more information about the installation of a standby system, order Engine-Generator Standby Electric Power Systems Installer’s Guide and Reference Manual (part #046622) from a Generac Authorized Service Dealer.

‹2.1.1 NFPA STANDARDS

The following published standards booklets pertain- ing to standby electric systems are available form the National Fire Protection Association (NFPA), Batterymarch Park, Quincy, MA 02269:

•NFPA No. 37, STATIONARY COMBUSTION ENGINES AND GAS TURBINES.

•Install the generator on high ground where water levels will not rise and endanger it.

•Allow sufficient room on all sides of the generator for maintenance and servicing. A good rule is to allow five feet of space on all sides.

•Where strong prevailing winds blow from one direction, face the generator air inlet openings into the prevailing winds.

•Install the generator as close as possible to the transfer switch. This reduces the length of wiring and conduit.

•Install the generator as close as possible to the fuel supply, to reduce the length of piping. HOWEVER, REMEMBER THAT LAWS OR CODES MAY REG- ULATE THE DISTANCE.

•NFPA No. 76A, ESSENTIAL ELECTRICAL SYS-

TEMS FOR HEALTH CARE FACILITIES.

•NFPA No. 220, STANDARD TYPES OF BUILDING CONSTRUCTION

•NFPA No. 68, GUIDE FOR EXPLOSION VENTING

•NFPA No. 70, NATIONAL ELECTRICAL CODE.

•NFPA No. 30, FLAMMABLE AND COMBUSTIBLE LIQUIDS CODE.

•NFPA No. 10, INSTALLATION, MAINTENANCE AND USE OF PORTABLE FIRE EXTINGUISHERS.

2.3GENERATOR MOUNTING AND

SUPPORT

Retain the generator compartment to a concrete slab with 1/4-inch masonry type anchor bolts. Be sure the bolts are long enough to retain the compartment. The slab should be at least six inches thick and should extend beyond the enclosure to a distance of at least three inches on all sides. See Section 7, Installation Diagram.

2.4BASIC STANDBY ELECTRIC

SYSTEM

Figure 2.1 shows a schematic diagram of a basic standby electric system. Both the UTILITY power supply and the STANDBY (generator) output are con- nected to an approved transfer switch. The transfer switch is required by electrical code and serves the following functions:

•Permits the LOAD circuits to be connected to only one power supply at a time.

•Prevents electrical backfeed between the generator and the UTILITY power circuits.

Notice that both the STANDBY and the UTILITY power supplies to the transfer switch are protected against overload by a main line circuit breaker.

Figure 2.1 – Basic Standby Electric System

2.2GENERATOR LOCATION

Install the generator set, in its protective enclosure outdoors, where adequate cooling and ventilating air always is available. Consider these factors:

•Install the unit where air inlet and outlet openings will not become obstructed by leaves, grass, snow, etc. If prevailing winds will cause blowing or drift- ing, consider using a windbreak to protect the unit.
