Wiring diagrams are provided in this section
showing the Model SB1029 wired for both 220V
and 440V. Refer to these diagrams if needed
when following this procedure. Additionally,
you must purchase 440V Conversion Kit (Part
No. PSB1029510) in order to complete the
conversion.
Hardwire setups require power supply lines to
be enclosed inside of conduit that 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 lock-out/tag-out safety programs
(commonly required by OSHA). Figure 13 shows
a simple diagram of a hardwire setup with a
locking disconnect switch between the power
source and the machine.
Hardwiring to Power Source
Due to the complexity required for planning,
bending, and installing the conduit necessary for
a hardwire setup, this type of setup can only be
performed by an experienced electrician.
For Electrician: Connect the incoming power
wires as shown in Figure 13.
