TRANSFER SWITCH

When the generator is used as a standby power supply, it must be equipped with a transfer switch which isolates it

from the utility’s distribution system. A transfer switch is designed to transfer electrical loads from the normal power

source (utility) to the emergency power source (generator) when normal voltage falls below a prescribed level. The

transfer switch automatically returns the load back to the normal source when power is restored back to operating

levels.

DANGER

FAILURE TO ISOLATE THE GENERATOR FROM THE NORMAL POWER UTILITY CAN

CAUSE POTENTIALLY LETHAL VOLTAGE TO BACKFEED INTO THE UTILITY LINES.

THIS MAY RESULT IN INJURY OR ELECTROCUTION OF UTILITY WORKERS NEARBY.

MAKE SURE THE GENERATOR IS ISOLATED BY A TRANSFER SWITCH FROM ANY

LOCAL UTILITY LINES. THIS ALSO APPLIES IF THE GENERATOR IS BEING USED

AS A BACK UP TO SOME OTHER TYPE OF POWER SUPPLY.

Installation of a transfer switch or other type of remote starting device is the responsibility of the generator user.

Installation of such devices must be performed by following all directions supplied by the manufacturer of the switch.

If attaching generator to a power supply normally serviced by a utility company, notify the utility company and check

local and state regulations. Familiarize yourself with all instructions and warning labels supplied with the switch.

WARNING

It is strongly recommended that ONLY a licensed electrician perform any wiring or

any related connections to the generator. Installation should be in compliance with

the National Electrical Code (NEC) as well as any state or local codes or regulations.

Failure to follow these procedures could result in property damage, personal injury

or death. Before any connections are attempted, make sure the main circuit breaker

switch is in the “OFF/O” position and the engine is turned off by pressing the Engine

Stop/Reset “O” button.

When using the generator as a standby or substitute power supply, make sure the output

voltage and phase rotation of the generator match those of the local power utility. Improper

voltage or phase rotation may cause equipment damage or malfunction.
