NOTE: Circuit breaker cover is removed for
illustration purposes.
A - Circuit Breaker — Protects the system from
shorts and other over-current conditions. Must be ON
to supply power to the Automatic Transfer Switch.
B - Generator Neutral Lug — Connection for neutral.
Neutral is not bonded to ground or generator.
C - Set Exercise Button — Used to set the exercise
cycle start time and day-of-the-week. Must be reset if
the fuse is removed or the battery is disconnected.
D- Manual Over-Ride Button — With the system
switch in AUTO position, push the manual over-ride
switch to start the generator. To turn off the generator,
push and hold the manual over-ride switch again until
engine stops.
E - 15 Amp Fuse — Protects the home generator DC
control circuits. If the fuse has ‘blown’ (melted open) or
was removed, the engine cannot crank or start.
F - System Switch — This two-position switch is the
most important control on the system and is used as
follows:
• “AUTO” position is the normal operating
position. If a utility power outage is sensed,
the system will start the generator. When
utility power is restored, AUTO lets the
engine stabilize internal temperatures, shuts
off the generator, and waits for the next
utility power outage.
• “OFF” position turns off running
generator, prevents unit from starting
and resets any detected faults.
G - Digital Display — Displays the total number of
hours the generator has been running and fault codes.
Used to schedule maintenance tasks and for
troubleshooting operational problems with the home
generator. All fault conditions are described in Fault
Description System.
H - Ten Pin Connection — Low Voltage connection
to signal fault contacts, transfer switch communication,
remote LED and auxiliary 12VDC power are made to a
removable ten-pin connector plug.
J - Generator Ground Lug — Located next to the
circuit breaker and should meet most codes,
standards, and regulations.
K - Utility Circuit Connection — Delivers power to
the generator’s circuit board (within internal battery
trickle charge) and water heater. When the power on
these leads is lost, the generator will start. Fuse
protected. Replace the fuse(s) only with identical
fuse(s).
L - Generator AC Lugs — Connection for generator
load(s).
