Installation
ASCO 4000 Series Automatic Open–Transition Transfer
Switches are factory wired and tested. Field installation
simply requires mounting and connection of service cables,
and auxiliary control circuits (if required).
Remove the Shipping Skid
For large switches, open the front door and remove the four
lag screws (2 in front, 2 in rear) securing enclosure to the
wood skid.
Supporting Foundation
The supporting foundation for the enclosure must level and
straight. Refer to the applicable enclosure outline drawing
included with the ATS for all mounting details including
door opening space.
If bottom cable entry is used, the foundation must be
prepared so that the conduit stubs are located correctly.
Refer to the enclosure outline drawing for specified area
and location. Provide cable bending space and clearance to
live metal parts. When a concrete floor is poured, use
interlocking conduit spacer caps or a wood or metal
template to maintain proper conduit alignment.
Mounting
Refer to the outline and mounting diagram provided with
the ATS; it shows all mounting details and instructions.
Protect the automatic transfer switch from construction
grit and metal chips to prevent malfunction or
shortened life of the transfer switch.
Mount the ATS vertically to a rigid supporting structure.
Level all mounting points by using flat washers behind the
holes to avoid distortion of the switch.
The controller is mounted on the cabinet door. An add-on
DIN rail is provided for some optional accessories and is
mounted below controller on the door.
De–energize the conductors before making any line or
auxiliary circuitry connections. Be sure that Normal
and Emergency line connections are in proper phase
rotation. Place engine generator starting control in the
OFF position. Make sure engine generator is not in
operation.
Testing Power Conductors
Do not connect the power conductors to the transfer switch
until they are tested. Installing power cables in conduit,
cable troughs and ceiling-suspended hangers often requires
considerable force. The pulling of cables can damage
insulation and stretch or break the conductor’s strands. For
this reason, after the cables are pulled into position, and
before they are connected, they should be tested to verify
that they are not defective or have been damaged during
installation.

Series 4000 Automatic Transfer Switch Operator’s Manual
Page 4 ASCO Power Technologies 381333-270D
Connecting Power Conductors
A Wiring Diagram is furnished with the ASCO 4000
Series ATS (separate from this manual). Refer to this
drawing. All wiring must be made in accordance with the
National Electrical Code and local codes.
After the power cables have been tested, connect them to
the appropriate terminal lugs on the transfer switch as
shown on the wiring diagram provided with the switch.
Make sure the lugs provided are suitable for use with the
cables being installed. Standard terminal lugs are
solderless screw type and will accept the wire sizes listed
on the drawings provided with the switch. Be careful
when stripping insulation from the cables; avoid nicking
or ringing the conductor. Remove surface oxides from
cables by cleaning with a wire brush. When aluminum
cable is used, apply joint compound to conductors.
Tighten cable lugs to the torque specified on rating label.
Do not run cables in front of or behind the switch. Cables
can be bundled on the right side of the switch. Maintain
proper electrical clearance between the live metal parts
and grounded metal: ½ inch minimum for 150-400 amps,
1 inch minimum over 400 amps.
It is not necessary to remove the barriers from the transfer
switches to install the cables. If you do remove them,
however, be sure to reinstall the barriers carefully.
Three cable spacers are included with 150, 200, & 230
amp transfer switches. When installing power cables, run
the cables through the cable spacers as shown in Figure 1.
Position the cable spacers within 1½ inches from the lugs.
The cable spacers must be located as shown
for 150, 200, and 230 ampere transfer switches.
Figure 1. Cable spacer for 150, 200, and 230 amp.
transfer switches.
Auxiliary Cable Boxes
For 1000 & 1200 amp. sizes, an auxiliary cable box is
required for all (normal, emergency, & load) bottom or top
entry. Order ASCO part no. 609027 if required.
On 1000 & 1200 amp. be sure to install auxiliary
cable box if both service and load cables are
entering through the top or bottom of enclosure.
Bus Connections
For large switches use grade 5 hardware to connect bus to
appropriate terminal plates. Wipe off the bus surfaces
before they are joined. If the bus is very dirty, gently
clean the surfaces with a non-flammable solvent. Avoid
touching the cleaned surfaces.
Tighten bolted joints to the torque specified in Table A.
The reliability of the connection depends
on how clean and how tight the joint is.

Controller Ground
A grounding wire must be connected to the controller’s
lower left mounting stud. Because the controller is
mounted on the enclosure door, a conductive strap must be
used between the enclosure and the door. This connection
provides proper grounding which does not rely upon the
door hinges.
Harnesses
The transfer switch is connected to the left side of the
control panel by a plug-in harness (two plugs).
Auxiliary Circuits
Connect auxiliary circuit wires to appropriate terminals on
the transfer switch. Note the control features that are
furnished on this switch. Make the necessary auxiliary
connections by referring to the Wiring Diagram.
