Safety Precautions
CAUTION
If you replace only the Main Unit of the E5DC, check the condition of
the Terminal Unit.
If corroded terminals are used, contact failure in the terminals may
cause the temperature inside the Digital Controller to increase,
possibly resulting in fire.
If the terminals are corroded, replace the Terminal Unit as well.
Loose screws may occasionally result in fire.
Tighten the terminal screws to the specified torque of 0.43 to
0.58 N·m.*
Set the parameters of the product so that they are suitable for the
system being controlled. If they are not suitable, unexpected
operation may occasionally result in property damage or accidents.
A malfunction in the Digital Controller may occasionally make control
operations impossible or prevent alarm outputs, resulting in property
damage. To maintain safety in the event of malfunction of the Digital
Controller, take appropriate safety measures, such as installing a
monitoring device on a separate line.
* The specified torque is 0.5 N·m for the E5CC-U.
