MOUNTING THE AUTOMATIC
TRANSFER SWITCH (A.T.S.)
*************
***** WARNING *****
*************
EQUIPMENT DAMAGE- Protect the switch from con-
struction grit and metal chips to prevent a malfunction
or shortened life of the switch.
The Automatic Transfer Switch connects the load (lights,
furnace, outlets, etc.) to the normal power line during
standby. When normal power fails, the A.T.S. starts
the engine generator set, disconnects the power line
and then connects the load to the standby generator
set. When normal power is restored, the automatic
switch retransfers the electrical load to the normal
service and stops the engine. The A.T.S. panel should
be mounted as close to the distribution panel as
possible.

***** 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 proceed-
ing!
PSS8000 - The Automatic Transfer Switch shipped with
the PSS8000 system has a 100 Amp line side
contactor installed to handle your normal power needs
and a 50 Amp generator side contactor to handle the
emergency generator output. Before installing the
A.T.S. you must first ensure that the 100 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 100 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 MAXI-
MUM OUTPUT OF THE GENERATOR IS 33.3 AMPS
AT 240 VOLTS. You must also take this into consider-
ation when deciding whether to install an emergency
distribution panel.
PSS12000 - The Automatic Transfer Switch shipped with
the PSS12000 system has a 100 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 100 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 100 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 MAXI-
MUM OUTPUT OF THE GENERATOR IS 50.0 AMPS
