1.16 BEFORE INSTALLATION
Before installing this equipment, check the ratings of both the generator and the transfer switch. Read “Emergency Isolation Method” and “Total Circuit Isolation Method” Sections 2.5 and 2.6.
The generator’s rated wattage/amperage capacity must be adequate to handle all electrical loads that the unit will power. The critical (essential) loads may need to be grouped together and wired into a sepa- rate “emergency” distribution panel.
This generator can be installed in conjunction with an engineered Generac “GTS” type transfer switch, if necessary.
The standard transfer switch has no sensing or con- trolling circuit boards. Instead, the generator control console houses a “Printed Circuit Board Assembly”, which controls all phases of operation, including engine start up and load transfer.
2.1STANDBY GENERATOR INSTALLATION
DANGER
Connecting this generator to an electrical sys- tem normally supplied by an electric utility shall be by means of a transfer switch, so as to isolate the electric system from the utility distri- bution 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.
