Mounting Guidelines
Mount the ACR90x0 Stand-Alone Controller before making any electrical
connections or applying power. The figures on the following pages illustrate
mounting specifications for the 2/4 Axis Configuration and the 6/8 Axis
Configuration of the controller. Figure 22 and Figure 23 on pages 66 and 67
provide the measurements. Figure 24 and Figure 25 on pages 68 and 69
show the clearance requirements. Use the following guidelines for mounting
the controller.
•
Mount the controller in proximity to the drive amplifiers and power
mains connection or terminal bus.
•
Mount the controller in a suitable metal enclosure, or under an
overhang, to prevent possible damage or injury. (See “Installation
Safety Requirements” on page 63.)
•
Mount it on an
unpainted metal surface
(preferably zinc-plated),
using three No. 8 or M4 mounting screws. For mounting
measurements, see Figure 22 on page 66 and Figure 23 on page 67.
•
For proper cooling, mount the controller vertically and with required
clearance. (See Table 4 on page 23 for cooling requirements. Figure
24 and Figure 25 on pages 68 and 69 illustrate mounting clearance
requirements.)
•
Avoid installing heat-producing equipment directly below the controller.
•
Make sure the ambient air temperature entering the controller, or rising
up to the controller, is within acceptable ambient temperature limits.
Under normal use, the temperature of air leaving the controller may be
25
°
C (45
°
F) above ambient temperature.
•
After installation, verify that the ambient air temperature directly below
the top-most controller does not exceed the Still Air maximum. For
ambient air temperature specifications, see Environmental
Specifications on page 23. In addition, make sure that nothing
obstructs the circulating airflow.
