CHAPTER 2 • CABINET SOLUTIONS

Note

If you’re using a preassembled backplate, the plug features two measures to ensure
that it’s always returned to their correct terminal block sections.

First, for visual confirmation, one part of the plug is blue (see Figure 2.7) and must be
visually matched up to a blue terminal block. The location of the blue piece rotates in
the different plugs and terminal block sections: in the first, the first block is blue, in
the second, the second is blue, etc.

Second, the plugs are keyed, as shown in the blue piece in Figure 2.7, so they will only
fit into their correct terminal block sections.
