CAUTION
Wire the SDC10 properly according to predetermined standards. Also wire
the SDC10 using specified power leads according to recognized installa-
tion methods. Failure to do so might cause electric shock, fire or faulty
operation.
Do not allow lead clippings, chips or water to enter the controller case.
Doing so might cause fire or faulty operation.
Firmly tighten the terminal screws at the torque listed in the specifications.
Insufficient tightening of terminal screws might cause electric shock or fire.
Do not use unused terminals on the SDC10 as relay terminals.
Doing so might cause electric shock, fire or faulty operation.
We recommend attaching the terminal cover (sold separately) after wiring
the SDC10. Failure to do so might cause electric shock, fire or faulty opera-
tion.
Use the relays on the SDC10 within the service life listed in the specifica-
tions.
Continued use of the relays after the recommended service life might cause
fire or faulty operation.
Use Yamatake Corporation’s SurgeNon if there is the risk of power surges
caused by lightning.
Failure to do might cause fire or faulty operation.
Make sure all wiring is correct. Incorrect wiring may damage connected
equipment.
The controller does not operate until six seconds after the power has been
turned ON. Special arrangements must be made when the relay output
from the controller is to be used as an interlock signal.
When a ground type thermocouple must be used and an external switch
input is required, PV readout error caused by sneak path current may oc-
cur. Select the insulated external switch input model (option code 03).

Terminal Array and Wiring
Before wiring, or removing/mounting the SDC10, be sure to turn the power
OFF. Failure to do so might cause electric shock.
Do not touch electrically charged parts such as the power terminals. Doing
so might cause electric shock.
