Installation 2-9
1560D-UM051D-EN-P – February 2005
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) [¼ 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.
Important: Refer to 2-high, Series B drawings in Publication
1500-UM055B-EN-P for power/ground bus connection.
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.
Control Cables
Control cable entry/exit should be located near the terminal blocks; customer’s
connections are to be routed along the empty side of the terminals. Nylon
cable tie loops are provided at the left, front corner of the cabinet to route
control cables safely behind the low voltage panel hinges. Cables should
be routed so they do not interfere with the swing of the low-voltage panels.
Fiber-Optic Cables
The small, gray, fiber-optic cables are fragile and must be protected during
installation from sharp bends and impact.
