Board installation
Inside the metal enclosure, there are slots for board insertions. These allow the
PC board to be positioned vertically (Figure 2 below). When you slide the board
between the grooves of the slots, make sure the terminal strip is toward the front
opening (toward you) to allow for the wire connections.

Wiring
Table 1 below lists wire lengths for one keypad at the end of the wire. When
connecting more than one keypad to the end of the wire, a higher gauge wire is
required.
