General Notes
- All dimensions are approximate, without tolerances.
- All dimensions are in inches unless otherwise noted.
- All dimensions are in [mm] unless otherwise noted.
- All dimensions are approximate, without tolerances.
- The control panel is connected to the transfer switch by means of a 12 wire cable. The transfer switch is factory configured for 30-100 Ampere units. For 150-200 Ampere units, the control cable must be extended by the user. Note: Wire No. 10 must be connected to terminal 10.
