Power Connection
Electrocution or fire
may occur if machine is
ungrounded, incorrectly
connected to power, or
connected to an undersized
circuit. Use a qualified
electrician to ensure a safe
power connection.
Hardwire setups require power supply lines to
be enclosed inside of conduit, which is securely
mounted and constructed in adherence to
applicable electrical codes.
A hardwire setup for this machine must be
equipped with a locking disconnect switch
as a means to disconnect the power during
adjustments or maintenance, which is a typical
requirement for many lock-out/tag-out safety
programs.
Figure 24 shows a simple diagram of a hardwire
setup with a locking disconnect switch between
the power supply and the machine.
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.

Connecting power supply wires to machine
without first disconnecting power supply may
result in serious injury or death.
To connect power supply wires to machine:
1.
Remove cover from power supply junction
box.
2.
Insert incoming power wires through strain
relief (see Figure 25) at bottom of junction
box, connect wires to terminals shown below,
tighten strain relief, then install junction box
cover.
3.
Shut off main power at power source circuit
breaker and attach wires to locking shut-off
switch.
Note: When using a phase converter, connect
the manufactured power leg or "wild wire"
to the terminal indicated in Figure 25).
This terminal can handle power fluctuation
because it is wired directly to the motor. The
other wires connect to the controls and must
be consistent to prevent damage.
