WINCO UL ATS (ASCO165)
The standby generator terminals in the A.T.S are
marked “ALTERNATE L2 & L6”. The “hot” leads X1 and X4
from the generator are connected to the terminals L2 &
L6.
The normal line power terminals in the A.T.S. are
marked “PREFERRED - L1 & L5”. The “hot” line power
leads are L1 and L3 from your normal power supply are
connected to terminals L1 and L3.
The load terminals in the A.T.S. are marked “LOAD - L3
& L7”. The leads to the load distribution panel are
connect to terminals L3 & L7.
The neutral leads from all three locations are con-
nected to the isolated terminal lugs on the sidewall of the
cabinet. This terminal block is labeled “NEUTRAL” and
the terminal lugs are mounted on red isolation standoffs.
If you are using separate ground leads from all
locations they are connected to the grounded terminal
lugs also on the side wall. This set of terminals is
labeled “GROUND”.
INSTALLATION NOTES
The load current carrying wires (L) and (T) must be
sized to handle the maximum load current without
excessive voltage drop. By code, the wire must be heavy
enough to handle the full current rating of the main line
circuit-breaker (or fuse) in the entrance (or sub-panel)
protecting the contactor switch.
All wires should be installed in rigid or flexible conduit.
(Knockouts are provided in the control box)
Because of the many different types of service, feeder,
and distribution equipment, no specific wiring instruc-
tions can be provided. It is, however, recommended that
only copper wire be used. In all cases it is essential that
while the load is connected to the generator, there can be
absolutely no feedback from the generator to the power
line or the power line to the generator. When properly
installed, the normal A.T.S. control and safety systems
will eliminate all paths for feedback. Check with your
local electrical inspector on applicable local, state and
federal codes.
*************
***** WARNING *****
*************
A service disconnect must be installed in front of the
A.T.S. panel as the A.T.S is not service entrance rated.
This will allow you to test the generator 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 and the service 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.
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 “Bat -”, and
“Start”.
The control wires will be connected as follows in the
generator control terminal box:
ATS Panel Generator Control Panel
Start 1 to Wire # S1, (Bat Neg)
Start 23 to Wire # S23 (Start)
ASCO 165 UL SWITCH
Your DC connection points in the ASCO 165 UL ATS are
on the terminal block in the upper right hand corner of the
ATS panel. The terminal block is numbered 1 through 9.
You will be using terminals 4 and 5, wire Start 23 will
connect to terminal #5 and wire Start 1 will connect to
terminal #4. See page 15 for a connection diagram.
SETTING THE EXERCISER CLOCK
WINCO Non-UL Only
SEE THE MANUAL SHIPPED WITH THE UL
ATS PANELS FOR THE PROPER PROCE-
DURE FOR SETTING THE WEEKLY
EXERCISE PROGRAMS ON ALL UL
SWITCHES.
Setting the current time and date.
1. Position the top right hand (RUN) slide switch to the
left position.
2. Push the clock’s “Day Select Button” until the clock
displays a triangle under the number corresponding to
the current day of the week. (Monday is day 1, Sunday is
day 7)
