Equipment Description
The automatic transfer switch is used for transferring electrical load from a UTILITY (NORMAL) power source
to an EMERGENCY (STANDBY) power source.
Mounting
• This model automatic transfer switch is designed for use only with Trane home standby generator sets.
• Install the transfer switch as close as possible to the electrical loads that are to be connected to it. Mount the
switch vertically to a rigid supporting structure.
• To prevent switch distortion, level all mounting points. If necessary, use washers behind mounting holes to
level the unit.
Connecting Power Source and Load Line
• Wiring diagrams and electrical schematics are provided in this manual.
• Before connecting wiring cables to terminals, remove any surface oxides from the cable ends with a wire
brush. All power cables should enter the switch next to transfer mechanism terminals. If ALUMINUM
conductors are used, apply corrosion inhibitor to conductors.
• Tighten terminal lugs to the torque values as noted on the decal located on the inside of the door. After
tightening terminal lugs, carefully wipe away any excess corrosion inhibitor.
