3-8 Installing the Sequence of Events Module
Choosing the
Extended-Depth Housing There are two housing options you must consider when wiring
your Sequence of Events module–standard-depth or extended-depth.
When you order an RTB for your module, you receive a
standard-depth housing with the RTB. If your application uses
heavy gauge wiring, you can order an extended-depth housing.
This housing does not come with an RTB.
You can use one of the housings listed in Table 3.2.
Figure 3.9 shows the difference, in terms of capacity, between the
housing options.

Use this
housing: with this RTB: This combination allows up
to this capacity of wires:
1756-TBCH Cage clamp 336 sq. mm
1756-TBS6H Spring clamp (36-position)
1756-TBE Any RTB that uses heavy
gauge wiring 628 sq. mm
IMPORTANT
The housings shown are used with a spring clamp
RTB, but the capacity for each remains the same
regardless of RTB type.
