Wiring Precautions
WARNING
Before connecting the DCP32 to the measurement target or external control
circuits, make sure that the FG terminal is properly grounded (100
Ω
max.).
Failure to do so might cause electric shock or fire.
Before wiring, 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.
CAUTION
Wire the DCP32 properly according to predetermined standards. Also wire
the DCP32 using designed power leads according to recognized installation
methods.
Failure to do so might cause electric shock, fire or faulty operation.
Do not allow lead clippings, chips or water to enter the DCP32 case.
Doing so might cause fire or faulty operation.
Inputs to the current input terminals
and
on the DCP32 should be
within the current and voltage ranges listed in the specifications.
Failure to do 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 DCP32 as relay terminals.
Doing so might cause electric shock, fire or faulty operation.
We recommend attaching the terminal cover (sold separately) after wiring the
DCP32.
Failure to do so might cause electric shock.
Use the relays on the DCP32 within the service life listed in the specifications.
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.
