CAUTION:
Please operate the modules of the MELSEC ST Series in the listed conditions only.
If the modules are used under other conditions, electric shock, fire, malfunction, dam-
ages or deterioration may be caused.
햲
This indicates the section of the power supply to which the equipment is assumed to be
connected between the public electrical power distribution network and the machinery
within premises. Category II applies to equipment for which electrical power is supplied
from fixed facilities. The surge voltage withstand level for up to the rated voltage of 300 V is
2500 V.
햳
This index indicates the degree to which conductive material is generated in the environ-
ment where the equipment is used. Pollution level 2 is when only non-conductive pollution
occurs but temporary conductivity may be produced due to condensation.
