Simplex 4100ES Installation Manual page 40

Figure 11 notes:
1. Dimensions shown are typical for all surface and semi-flush installations.
2. Use suitable punch when conduit is required. Knockouts are not provided. Locate and create on-site as required during
installation.
3. A minimum clearance of 5 inches (127mm) from the hinge side is required to provide a maximum door opening of 90 degrees.
4. Do not install any power-limited wiring in the shaded area of the back box as shown in Figure 11. This area is reserved for non
power-limited devices and circuits (for example, AC power, batteries, and city circuits). The non power-limited area is determined
by the internal barriers, but is always below and to the right of these barriers.
5. Minimum distance between boxes is 3 ¼ inches (83 mm). Maximum distance between boxes is 10 inches (254 mm).
