(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 33.3 AMPS AT 240 VOLTS. You must
also take this into consideration when deciding whether
to install an emergency distribution panel.
PSS12000 - The Automatic Transfer Switch shipped
with the PSS12000 system 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 com-
plete 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 50.0 AMPS AT 240 VOLTS. You must
also take this into consideration when deciding whether
to install an emergency distribution panel.
PSS20000 - The Automatic Transfer Switch shipped
with the PSS20000 system has a 230 Amp line side
contactor installed to handle your normal power needs
and a 150 Amp generator side contactor to handle the
emergency generator output. Before installing the A.T.S.
you must first ensure that the 230 Amp line side contac-
tor will be sufficient to handle your complete service. See
Figure 5. (i.e. the main line breaker must not be larger
than 230 Amps). If you have a larger main line breaker,
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
83 AMPS AT 240 VOLTS SINGLE PHASE, 56 AMPS AT
208 VOLTS AND 48 AMPS AT 240 VOLTS THREE PHASE.
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. Both AC and DC
connections are made behind this panel. Three AC
power leads are required between the generator and the
A.T.S. The two power leads are marked G1 and G3, the
neutral lead is shipped bonded to the ground lug. If your
local code requires the generator to be wired with an
isolated neutral, remove this neutral to ground bond.
This will require you to run four AC leads from the
generator to the A.T.S. as you will need to run both a
neutral and a ground lead. All wires must be sized to
handle 33 Amps 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.
A.T.S .Connections
The standby generator terminals in the A.T.S are
marked “GENERATOR - G1, G-N, G3”. The “hot” leads G1
and G3 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.
PSS12000 SINGLE PHASE
Generator Connections
To gain access to the customer connections remove
the end panel opposite the muffler. Both AC and DC
connections are made behind this panel. Three AC
power leads are required between the generator and the
A.T.S. The power leads coming into this connection box
from the generator end are run in parallel. (i.e. G1-A and
G1-B are both connected to the G1 lead and G2-A and
G2-B are both connected to the G3 lead going to the
A.T.S.) CAUTION THE G3-A AND G3-B LEADS ARE
NOT USED IN THE SINGLE PHASE INSTALLATION,
JUST LEAVE THEM CAPPED IN THE BOX. The voltage
regulator leads are currently connected to some of the
generator leads. These leads must remain with the
generator leads they are connected to. The neutral lead
(GN-A & GN-B) are shipped bonded to the ground lug. If
your local code requires the generator to be wired with an
isolated neutral, remove this neutral to ground bond.
This will require you to run four AC leads from the
