Connecting to Power

Due to the complexity required for planning, bending, and installing the conduit necessary for a code-compliant hardwire setup, an electrician or other qualified person MUST perform this type of installation. Hardwire setups typically require power supply wires to be enclosed inside of a solid or flexible conduit, which is securely mounted at both ends with the appropriate conduit fittings. All work must adhere to the required electrical codes.

The hardwire setup for this machine must include a locking disconnect switch (see Figure 15) between the power source and the machine. This switch serves as the means to completely disconnect the machine from power to prevent electrocution accidental startup during adjustments, maintenance, or service to the machine.

Electrocution or death will occur if this procedure is attempted with live power supply wires. All wiring going to the machine must be disconnected from the power source, and the power supply shut OFF and locked out before performing this procedure.

The incoming power wires must be connected to the three terminals on the master power switch marked L1, L2, and L3, and the incoming ground wire must be connected the ground terminal shown in Figure 16. All wires must have adequate slack and be clear of sharp objects.
