3 INSTALLATION AND MODULE MOUNTING

3.1 Where to Install

The programmable controller does not have a fire-proof, dust-proof, and water-proof structure, so
it must be housed in a dust- and water-proof steel cubicle, as shown below, and must be installed
in a location where no water will get into the controller.
In installation locations where there is a possibility of water leak, be sure to house
the programmable controller in a water-proof enclosure. Disregarding this rule
may result in hardware damage.
