AT 240 VOLTS. You must also take this into consider-
ation when deciding whether to install an emergency
distribution panel.
PSS20000 - The Automatic Transfer Switch shipped with
the PSS20000 system has a 225 Amp line side
contactor installed to handle your normal power needs
and a 100 Amp generator side contactor to handle the
emergency generator output. Before installing the
A.T.S. you must first ensure that the 225 Amp line side
contactor will be sufficient to handle your complete
service. See Figure 5. (i.e. the main line breaker must
not be larger than 225 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 distribu-
tion 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 important safety precautions yourself with
reliable instruments before proceeding.
A.C. ELECTRICAL CONNECTIONS

***** WARNING *****
*************
A FUSED DISCONNECT MUST BE INSTALLED
BETWEEN THE GENERATOR AND THE A.T.S.
PANEL TO PREVENT OVERLOADING AND BURN-
ING OUT THE GENERATOR. FAILURE TO PRO-
VIDE A FUSED DISCONNECT, RATED AT GENERA-
TOR RATING WILL VOID YOUR WARRANTY IN
CASE OF GENERATOR FAILURE.

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 are prewired 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” leads L1 and L3 are prewired 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 prewired 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 connec-
tion 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 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 50 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 are prewired 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” leads L1 and L3 are prewired 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 prewired 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.
