NOTE:
Code requires a fuse disconnect (circuit breaker) be
installed in the incoming power line wiring directly in front
of the A.T.S. panel. This will allow you to test the genera-
tor under load. Should you ever have to work on the
switch, you will be able to disconnect the power and work
on the switch cold without having the power company pull
your meter.
To wire the automatic transfer switch into the existing
wiring, first determine which circuits will be on the
emergency load circuit. If the entire load is to be trans-
ferred, the transfer switch can be wired in directly after the
watt-hour meter or main entrance providing the service
entrance ampere rating is within the transfer switch’s
rated capability.
If only specific circuits are to be powered under
emergency power failure conditions, an additional
distribution panel designated “emergency distribution
panel” must be installed.
All selected emergency circuits are removed from main
distribution panels and reinstalled in the emergency
distribution panel. Suggested circuits: freezer, refrigera-
tor, furnace, emergency lights, sump pump, emergency
outlet circuits, etc. Total running load must not exceed
generator rating.
AUTOMATIC TRANSFERS SWITCH
CONNECTIONS UL-ATS
See the manual shipped with the Automatic Transfer
Switch for connection locations in the switch. Connec-
tions in each switch will vary depending on the type of
switch and the manufacturer.
*************
***** WARNING *****
*************
All UL transfer switches are phase rotation sensitive
and voltage sensitive. If you can not get the line power
or the generator to operate the ATS properly check
both your phase rotation on three phase switches and
proper voltage levels on all switches.
D.C. ELECTRICAL INTERCONNECTION
*******CAUTION******
Never run the AC and DC wiring in the same conduit.
WINCO NON-UL ATS
Two control wires are required to be installed between
the A.T.S. panel and the generator control terminal box.
Depending on the distance 14 to 16 gauge stranded wire
should be used. These wires will be labeled “Start 1”,
and “Start 23”.
The control wires will be connected as follows in the
generator control terminal box:
ATS Panel Generator Control Panel
Start 1 to Wire #S1
Start 23 to Wire #S23
The control wires will be connected in the generator
control terminal box and in the A.T.S. to small terminal
blocks. Both are labeled “Start 1” and “Start 23”. The
wires are run between identical terminals, i.e. “Start 1” to
“Start 1” etc.
UL ATS
Winco\Zenith
The only significant difference when make your DC
connections in the UL ATS is the terminal markings in the
UL ATS. Instead of being marked “Start 1” and Start 23”
they are marked start contacts “X1” and “X2”. The wire
labeled “Start 1” is routed to start contact X1” and the wire
labeled “Start 23” is routed to start contact “X2”
ASCO 165 UL SWITCH
Your DC connection points in the ASCO 165 ATS are
terminals “4” and “5 on the interface terminal block.
