Chapter 2 Installation
Installation Physical Location
The controller is designed for limited front access (components may have to be
removed) and should be installed with adequate and safe clearance to allow for
total door opening. The back of the unit may be placed against a wall and several
units may be set end to end. In special cases where floor space is limited and the
unit is not against a wall, certain cabinet sections may be placed back to back.
This requirement must be stated in the specifications in order to mechanically
alter the controller.
Fan
The controller may include a cooling fan which is used to cool the component. It
should be checked for free operation and no obstruction of the airflow.
Ground Bus Bar
Controllers which are delivered in two (or more) sections, or retrofit controllers,
will require that the ground bus bar (6 mm x 51 mm) [1/4 in. x 2 inches], which
runs the entire length of the equipment in the center back side, be reconnected. A
mechanical lug for #8-#10 AWG or #6-250 MCM cable is supplied at the
incoming end of the line-up. When the sections are brought together, bus links
are used to connect the bus bars.
Power and Control Wiring
Controllers consisting of two or more sections will require that the power and
control wiring be connected per the schematic drawings provided.
TIP Rockwell Automation can assist with the selection of an appropriate
interlocking method, which may include mechanical modifications to the
cabinet(s) or key-type lock systems.
TIP An auxiliary cabinet may be attached to the main structure. It will be ram-
interlocked with the main power cell door, which will not allow it to be opened
until the main power cell door is opened.
IMPORTANT Refer to 2-high, Series B drawings in Publication 1500-UM055_-EN-P for
power/ground bus connection.
