REMOTE START TERMINAL BLOCK
The remote start terminal block is located just under the two 120V duplex convenience outlets. It
provides a connection for installation of a remote start switch which will allow the generator to be
started by a remote dry-contact closure switch.
Before pressing the “AUTO” button (or moving the toggle switch to the REMOTE START position
on analog units), verify that the contacts on any remote switch linked to the generator are OPEN.
If the contacts on a remote switch are closed, the generator will crank and start when AUTO (or
REMOTE START) is selected. Attach the switch leads to the two unused terminals on the
generators remote start block. For additional information on starting the generator, see GEN-
ERATOR START UP on page 20.
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.

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 THAT 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.
