Mounting the Control
When mounting the control take the following precautions.
• DO NOT mount in direct sunlight.
• DO NOT mount on surfaces with temperature above 104°F (40°C).
• DO NOT allow the ambient temperature around the ACS 501 to exceed
the ambient temperature as stated in Environment above.
• Mount the ACS 501 vertically with the factory supplied conduit knockouts
at the bottom.
• See Figure 3-1 for the space requirements.
• If units are to be mounted next to each other, each unit must have two
inches (50 mm) of clear space, so that a total of four inches (100 mm)
between two units is available for proper cooling.
• If units are mounted one above the other, at least 12 inches (300 mm) is
required between the units.
• At least three (3) separate grounded conduits are required. One each for
input, output, and control wiring.
Figure 3-1 shows the space requirement for adequate cooling of the ACS 501.
