***** 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.
A.C. ELECTRICAL CONNECTIONS
*************
***** 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 first
remove the top cover and then 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 installa-
tion are made behind this panel. After removing the end
panel you will need to remove the cover over the connec-
tion box in the upper right hand corner. Knockouts are
provided on the outside of the enclosure for your conve-
nience. 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 distribu-
tion panel. The two power leads from the generator are
marked G1 and G3.
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.
The last two wires you will need are the DC control
leads for the start circuit in the A.T.S. These last two
connections wil be discussed later in more detail.
A.T.S .Connections - for standard Non-UL WINCO ATS
The standby generator terminals in the A.T.S are
marked “GENERATOR - G1, G-N, G3”. The “hot” leads #1
and #4 from the generator are wired to the generator side
contactor, terminals G1 and G3.
The line terminals in the A.T.S. are marked “LINE - L1,
L-N, L3”. The “hot” line leads L1 and L3 are wired to the
line side contactor, terminals L1 and L3.
The load terminals in the A.T.S. are marked “LOAD - T1,
T-N, T3”. The “hot” leads T1 and T3 are wired to the
bottom side of both the line side and the generator side
contactor.
If you are using a separate ground lead it is routed to
the ground lug in the A.T.S.
