Assembly and Installation
Safety is a primary consideration in programmable controller installations and
operations. The procedures in this section consider the safety of the operator, of
the controlled equipment and of the Controller. These procedures are intended
to supplement the applicable codes and ordinances that govern wiring and
installation practices. Personnel installing the Controller system should become
familiar with local codes as well as these procedures.
A well-planned layout is essential for the installation of the Mini-PLC-2/15
Controller. Various considerations necessary for planning the installation are
discussed in this section.
Once the layout is planned, the Controller components can be assembled and
installed into a workable system. The sequence of events presented in this
section is a suggested approach to facilitate the assembly and installation of the
components.
CAUTION: To avoid equipment damage, thoroughly read and
understand this entire Manual before installing or operating the
Mini-PLC-2/15 Controller.
There are general recommendations to consider for layout of the Controller
system. These recommendations are the result of both product testing and
Allen- Bradley’s cumulative experience with solid state industrial controls.
They provide useful guidelines for most Mini-PLC-2/15 Controller installations.
These recommendations are intended to make the Controller an integral part of
the user’s manufacturing facility. Some of the installation recommendations for
user-supplied equipment are general in nature. Environmental conditions, the
individual application and local codes and ordinances dictate the specific types
of layout and wiring of user-supplied installation equipment.
Environmental Considerations
Special care should be taken in industrial environments that may contain one or
more conditions adverse to solid state controls. The user’s plant may include
equipment which produces heat or electrical noise. Line voltage variations
may also occur in some locations.
