4.2.5 Replacing Control Output Relays
This subsection describes how to replace the control output relays.
Since inspection is needed in case of parts replacement, the replacement work should be
carried out by a YOKOGAWA engineer or an engineer certified by YOKOGAWA. When
replacement is required, contact your nearest YOKOGAWA dealer.
CAUTION
Always turn off the power before starting the work in order to avoid electric shock.
Do not pull out the internal unit for any other purpose other than to replace the control
output relays.
