12.1 General specifications
With the models QX10, QX10-TS, QX28, QY10, QY10-TS, QY18A and QY22 the peak value of the noise voltage
is 1500 V.
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.
This index indicates the degree to which conductive material is generated in terms of the environment in which
the equipment is used. Pollution level 2 is when only non-conductive pollution occurs. A temporary conductivity
caused by condensing must be expected occasionally.

CAUTION:
Do not use or store the programmable controller under pressure higher than the
atmospheric pressure of altitude 0 m. Doing so can cause a malfunction.
When using the programmable controller under pressure, please contact your sales
representative.
