Protect the Circuit Board from Contamination
The printed circuit boards of the modules must be protected from dirt, oil,
moisture, and other airborne contaminants. To protect these boards, we
recommend installing the system in an enclosure suitable for the environment.
Keep the interior of the enclosure should clean and the enclosure door closed
whenever possible.
Power Supply Distance
You can install as many modules as your power supply can support. However, the
module has a power supply distance rating of four, which means that it can not be
more than four modules away from the system power supply.
The illustration provides an example of determining power supply distance.
