Analog input signal:
For signal input from externally installed

Note: Installation category, called over-voltage
category, specifies impulse withstanding
voltage. Category II is for electrical equip-

Pollution degree indicates the degree of
existence of solid, liquid, gas or other
inclusions which may reduce dielectric
strength. Degree 2 is the normal indoor
environment.
