C3. Maintenance in Hazardous Area
To carry out maintenance, check the power supply, ground and network cable for looseness.
Explosion-proof instruments must retain their intended properties before and after maintenance.
Otherwise, hazardous conditions can arise. Be sure to consult with Yokogawa for any repair and
alteration.
For other field wireless network components, see the User’s Manual of the relevant device.
