Make sure any problems that caused the main circuit
breaker to trip are corrected before returning the switch
to the ON (I) position.
NOTE: The main circuit breaker interrupts power to the
connection lugs only. The receptacle panel has power
even if the main circuit breaker is in the OFF (O) position.
The receptacle panel main circuit breaker, located next to
the main circuit breaker, will disconnect all power to the
receptacle panel.
Remote Start Terminal Block
The remote start terminal block provides a connection for
installation of a remote start switch which will allow the
unit to be started by a remote dry-contact closure switch.
To locate the remote start terminal block, see
Control
Panel.

1. Before entering Auto mode, verify that the contacts
on any remote switch linked to the unit are OPEN.
If the contacts on a remote switch are closed, the
engine will crank and start when Auto mode is
entered.
2. See
Figure
3-20. Attach the switch leads to the
two unused terminals on the unit's remote start
terminal block (A). For additional information, refer
to
Starting the
Unit—Auto/Remote.
Transfer Switch
When the unit 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.
WARNING
Phase rotation must be compatible.
Incompatible phase rotation could result
in equipment damage, death or serious injury.

of such devices must be performed by following all
directions supplied by the manufacturer of the switch. If
attaching the unit 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.
Only a trained and licensed electrician should perform
wiring and connections to unit. Failure to follow proper
