Mechanical Requirements

Dimensions

The following figure gives the dimensions of the size 1 (left) and size 2 (right) blocks:

The following tables give the sizes of the blocks:

Spacing Requirements

TM7 blocks can be installed side-by-side. However, you must observe the minimum spacings from the front face of each expansion block, based on cable connector type and cable bend radius.

The following figure shows an example of wire bending requirements for a block connected with pre-wired straight cables and elbowed cables:

1 Straight cable

2 Elbowed cable
