Mounting
To mount the ASCO Automatic Transfer Switch, refer to the outline and mounting diagram shipped with the ASCO ATS and mount the transfer
switch according to details and instructions shown in the ASCO ATS Installation manual. Mount it vertically to a rigid supporting structure. Level all
mounting points by using flat washers behind the holes to avoid distortion of the transfer switch.
Power Cables
Test the conductivity of the power cables before installation. Then connect them to the appropriate terminal lugs on the transfer switch as shown on
the wiring diagram provided with the transfer switch. Make sure that the lugs provided are suitable for use with the cables being installed. Standard
terminal lugs are the solderless screw type and accept wire sizes listed on the drawings provided with the transfer switch. 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.
