INSTALLATION (continued)
Tighten bolted joints to the torque specified in Table A.
The reliablility of the connection depends on how clean and how tight the joint is.
Table A. Tightening torque values for bolted joints
(Grade 5 hardware)
Bolt Diameter | Tightening Torque |
in inches | in foot pounds |
1/4 | 7 |
5/16 | 12 |
3/8 | 20 |
1/2 | 50 |
5/8 | 95 |
3/4 | 155 |
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
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.
Engine Starting Contacts
The engine control contact connections (if used) are located on the transfer switch. Connect signal wires to appropriate terminals as specified in Table B and shown in Figure

Functional Test
The Functional Test consists of three checks:
V1 — Manual Operation Test, page
V2 — Voltage Checks, page
V3 — Electrical Operation, page
Do these checks in the order presented
to avoid damaging the ATS.
Read all instructions on the Wiring Diagram and labels affixed to the ADTS. Note the control features that are provided and review their operation before proceeding.
