(3) Installation surface
Install the base unit on a flat surface. If the surface where the base unit is installed is not even, this may strain the
printed circuit boards and cause malfunctions.
(4) Installation in an area where other devices are installed
Do not install a base unit in proximity to vibration sources such as large magnetic contractors and no-fuse circuit
breakers. Install a base unit on a separate control panel or away from vibration sources.
