This chapter will help you:
Connect the field wiring arms of chassis A and B
install either ungrounded or grounded 120V AC power distribution
Before continuing, be sure that you configured your clutch/brake
controller chassis and modules as shown in chapter 3. For installation
details, refer to the installation publication for your processor. These
publications are listed in our Publications Index (publication SD499).
In order to design, build, install, and operate a safe press system, you
should also refer to other publications. In addition to local codes and
laws, adhere to safety requirements detailed in the following publications.
OSHA Regulations, Title 29-Labor, Chapter XVII, Section 1910.217,
