Baseplate Mounting Dimensions
Note:
Series 90-30 PLCs must be mounted in a protective enclosure. The enclosure should be
capable of properly dissipating the heat produced by all of the devices mounted inside it.
For details on calculating heat dissipation, refer to Appendix F.
Series 90-30 PLC baseplates are designed to be panel mounted. Each baseplate has standard
attachment flanges for mounting on an electrical panel. Baseplate dimensions and proper spacing
requirements for installation purposes for both the 5 and 10-slot baseplates with embedded CPU
(Models 311 and Model 313 are 5-slot baseplates; Model 323 is a 10-slot baseplate), and the 5 and
10-slot baseplates for Modular CPUs are shown in figures 3-1 through 3-4.
Note
All 5-slot baseplates have the same mounting dimensions and all 10-slot
baseplates have the same mounting dimensions.
Baseplates
must
be mounted in
the orientation as shown in the following figures for proper cooling.
