SECTION 1 INSTALLATION
1---1
ASCO 4000 Series Automatic DelayedTransition Trans-fer Switches are factory wired and tested. Field installa-tion 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 leveland straight. Refer to the applicable enclosure outlinedrawing included with the 4ADTS for all mounting
details including door opening space.
If bottom cable entry is used, the foundation must beprepared so that the conduit stubs are located correctly.Refer to the enclosure outline drawing for specified area
and location. Provide cable bending space and clearanceto live metal parts. When a concrete floor is poured, use
interlocking conduit spacer caps or a wood or metaltemplate 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 switch from construction gritand metal chips to prevent malfunction or
shortened life of the automatic switch switch.
Mount the ATS vertically to a rigid supporting structure.
Level allmountingpoints by using flat washers behind theholes to avoid distortion of the switch.
The controller is mounted on the cabinet door. An add-on DIN railis provided for some optional accessoriesand
is mounted below controller on the door.
Deenergize the conductors before making anyline or auxiliary circuitry connections. Be surethat Normal and Emergency line connectionsare in proper phase rotation. Place engine gen-erator 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 transferswitch until they are tested. Installing power cables inconduit, cable troughs and ceiling-suspended hangers
often requires considerable force. The pulling of cablescan damage insulation and stretch or break theconductors 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 orhave been damaged during installation.
Connecting Power Conductors
AWiringDiagramis furnished with theASCO 4000 Series4ADTS (separate from this manual). Refer to this
drawing. All wiringmust be made in accordance with theNational Electrical Code and local codes.
After the power cables have been tested, connect them to
the appropriate terminal lugs on the transfer switch asshown 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 solder-less screw type and will accept the wire sizes listed on thedrawings provided with the switch. Be careful whenstripping insulation from the cables; avoid nicking or
ringing the conductor. Remove surface oxides fromcables by cleaning with a wire brush. When aluminumcable 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 theswitch. Cablescan be bundled on the right side of the switch. Maintain
proper electrical clearance between the live metal partsand grounded metal: 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 removethem,however, be sure to reinstall the barriers carefully.
Bus Connections
For large switches use grade 5 hardware to connect bus toappropriate terminal plates. Wipe off the bus surfacesbefore they are joined. If the busis very dirty, gentlyclean
the surfaces with a non--- flammable solvent. Avoidtouching the cleaned surfaces.
Tighten bolted joints to the torque specified in Table A.
The reliability of the connection dependson how clean and how tight the joint is.

Controller Ground
A grounding wire must be connected to the controllers
lower left mounting stud. Because the controller ismounted on the enclosure door, a conductive strap mustbe used between the enclosure and the door. This
connection provides proper grounding which does notrely upon the door hinges.
HarnessesThe transfer switch is connected to the left side of thecontrol panel by a plug-in harness (two plugs).
Auxiliary Circuits
Connect auxiliary circuit wires to appropriate terminalson the transfer switch. Note the control features that arefurnished on this switch. Make the necessary auxiliary
connections by referring to the Wiring Diagram.
Engine Starting Contacts
The engine control contact connections (if used) arelocated on the transfer switch. Connect signal wires toappropriate terminals as specified in Table B and shownin Figures 11 and 12. See the wiring diagram too.
