Mounting the Terminal Blocks
You can mount the MDF hardware in one of the following three ways:
Directly to a wall
On a wall-mounted frame
On a self-supported frame
Table 7-5, Mounting Methods. is a mounting guide for the number of modules appropriate for each
mounting method. Remember to factor in available space with the number of modules when you select
your mounting method.
Number
of Modules
9 & u p
Frame mounting of the terminal blocks for installations of all module sizes is desirable but those of 9
modules or more must be frame mounted.
Arranging the Terminal Blocks
Arrange the terminal blocks with the following factors in mind:
Cable terminations to the fields and how the fields cross-connect
The type of port fields and the necessity for short jumper lengths
Possible zone configurations
These factors are discussed in the sections that follow.
Cable Terminations and Cross-Connections. Terminate the equipment port cables close to the
distribution cables, as suggested in figure 7-7, Four-Area MDF, to make connecting and disconnecting
the jumper wires as easy as possible. Figure 7-7 is only a possible configuration; vary the field design if
it is more useful for a particular application.
