***** WARNING *****
*************
All wiring must be done by a licensed electrician, and
must conform to the national electrical code and comply
with all state and local codes and regulations. Check with
your electrical inspectors before proceeding!
The non UL Automatic Transfer Switch shipped with
these systems has a 110 Amp line side contactor
installed to handle your normal power needs and a 60
Amp generator side contactor to handle the emergency
generator output. Before installing the A.T.S. you must
first ensure that the 110 Amp line side contactor will be
sufficient to handle your complete service. See Figure 3.
(i.e. the main line breaker must not be larger than 110
Amps) If you have a 125, 150 , 200 Amp or larger
system, you will not be able to transfer the complete
electrical system. In this case it will be necessary to
install a secondary emergency distribution panel. See
Figure 4. NOTE: THE MAXIMUM OUTPUT OF THE
GENERATOR IS 40 AMPS AT 240 VOLTS. You must also
take this into consideration when deciding whether to
install an emergency distribution panel.
************
***** DANGER *****
*************
Be certain the operation selector switch on the front of the
A.T.S. Control is in the “stop” position and the main power
switch “off”. For your own protection, verify these impor-
tant safety precautions yourself with reliable instruments
before proceeding.

***** WARNING *****
*************
A FUSED DISCONNECT OR CIRCUIT BREAKER
MUST BE INSTALLED BETWEEN THE GENERATOR
AND THE A.T.S. PANEL TO PREVENT OVERLOADING
AND BURNING OUT THE GENERATOR. FAILURE TO
PROVIDE A FUSED DISCONNECT OR CIRCUIT
BREAKER, RATED AT GENERATOR RATING WILL VOID
YOUR WARRANTY IN CASE OF GENERATOR FAIL-
URE.
Generator Connections
To gain access to the customer connections Remove
the end panel opposite the muffler. All connections
including AC & DC connections to the ATS, 120 Volt
power connection for battery charger, fuel line connection
and battery installation are made behind this panel. After
removing the end panel you will need to remove the cover
over the connection box in the upper right hand corner.
Knockouts are provided on the outside of the enclosure
for your convenience. Three AC power leads are
required between the generator and the A.T.S. a fourth
lead will be required if you are required by code to
provide an isolated neutral. The units are shipped with
the neutral bonded to ground. If you need to run an
isolated neutral, you will need to remove the generator
neutral leads from the ground lug mounting bolt where
they are attached. You will then need to run both a
neutral and a ground lead in addition to the two power
leads all the way back to your distribution panel. The two
power leads from the generator are marked X1 and X4.
All power leads from the generator to the A.T.S. must
be sized to handle rated generator output amperage at a
minimum, the type of wire you use will determine the
gauge required. Consult your local wire supplier for
proper gauge and type for your area.
In addition to the power leads you will also need to run
a three wire 120 volt, 15 amp circuit from your distribution
panel to the generator. This circuit will be used to power
the battery charger.
