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.

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.
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.
When the wiring job is complete, close and lock
the main electrical box door, otherwise the
machine control panel will be disabled.
