Section 2 — Installation

Guardian Liquid-cooled 40 kW Generator

STANDBY GENERATOR INSTALLATION

DANGER

Connecting this generator to an electrical system normally supplied by an electric utility shall be by means of a transfer switch (such as the Generac “GTS” type transfer switch), so as to isolate the electric system from the utility distribution system when the generator is operating. Failure to isolate the electric system by these means will result in damage to the generator and may also result in injury or death to utility workers due to backfeed of electrical energy.

If an open bottom is used, the engine-generator is to be installed over non-combustible materials and should be located such that combustible materials are not capable of accumulating under the generator set.

Only qualified, competent installation contractors or electricians thoroughly familiar with applicable codes, standards and regulations should install this standby electric power system. The installation must comply strictly with all codes, standards and regulations per- taining to the installation.

This genset must be installed on a level surface. The base frame must be level within two (2) inches all around.

After the system has been installed, you must not do anything that might render the installation in noncom- pliance with such codes, standards and regulations.

NOTE:

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

2.1BASIC STANDBY ELECTRIC SYSTEM

Figure 2.1 shows a schematic diagram of a basic stand- by electric system. Both the UTILITY power supply and the STANDBY (generator) output are connected 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 STANDBY power 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.

NOTE:

Generac recommends the use of a Generac Power Systems “pre-packaged” type transfer switch (Part No. 0D4406) in conjunction with this generator.
