ground rules need to be followed first. The basic guidelines regarding the safe
handling of electrical components are documented below will help users while
working with electricity.

personnel.
2.3.2. Environmental condition consideration
In order to prevent irreparable component damage, the instrument must be
installed in room temperature with low humidity, no corrosivity and no direct
sunlight exposure.

The signal cables in the instrument should be separated from the power
lines and machines that produces high noise interference which affects the
performance of the controller significantly.
