    Installation Before Installation Procedure Before installing, removing, inspecting or performing any maintenance on the hoist, the main switch shall be de-energized and locked out and tagged out. Do not use this equipment in hazardous locations. Before installing, make sure your electrical supply meets the minimal requirements for the unit and check the gauge wire calculator using the QR code below.

  • Page 51: Supply Voltage

    • Never bypass limit switches, remove limit switch stops, or alter limit switch devices. • Check the electric installation and wire gauge selection at www.prowinch.com and follow these simple steps). • If the unit has three phase, do not alter or bypass the phase (shifter, need to confirm the term).
