WARNING
Before removing, mounting, or wiring the DCP31, be sure to turn off the power to
the DCP31 and all connected devices.
Failure to do so might cause electric shock.
Do not disassemble the DCP31.
Doing so might cause electric shock or faulty operation.
Before connecting the DCP31 to the measurement target or external control cir-
cuits, make sure that the FG terminal is properly grounded (100 Ω max.).
Failure to do so might cause electric shock or fire.
Turn the DCP31 OFF before starting wiring.
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
Use the DCP31 within the operating ranges recommended in the specifications
(temperature, humidity, voltage, vibration, shock, mounting direction, atmo-
sphere, etc.).
Failure to do so might cause fire or faulty operation.
Do not block ventilation holes.
Doing so might cause fire or faulty operation.
Do not allow lead clippings, chips or water to enter the DCP31 case.
Doing so might cause fire or faulty operation.
Wire the DCP31 properly according to predetermined standards.
Also wire the DCP31 using designed power leads according to recognized instal-
lation methods.
Failure to do so might cause electric shock, fire or faulty operation.
Inputs to the current input terminals 31 and 33 on the DCP31 should be within
the current range 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 DCP31 as relay terminals.
Doing so might cause electric shock, fire or faulty operation.
We recommend attaching the terminal cover (sold separately) after wiring the
DCP31.
Failure to do so might cause electric shock.

iv
CAUTION
Use the relays on the DCP31 within the service life listed in the specifications.
Continued use of the relays after the recommended service life might cause fire
or faulty operation.
If there is a risk of a power surge caused by lightning, use a surge absorber (surge
protector) to prevent fire or device failure.
Before replacing the battery, be sure to turn the power OFF.
Failure to do so might cause electric shock.
Do not touch internal components immediately after turning the power OFF to
replace the battery.
Doing so might cause burns.
•Do not insert the battery with the polarities (+, -) reversed.
• Do not use damaged (broken battery skin, leaking battery fluid) batteries.
• Do not throw batteries into fires, or charge, short-circuit, disassemble or heat
batteries.
• Store batteries in low-temperature, dry locations.
Failure to observe the above cautions may cause batteries to emit heat or split, or
battery fluid to leak.
Store batteries out of the reach of small children.
Batteries are small and are easy to swallow. If a child swallows a battery,
consult a physician immediately.
When disposing of used batteries at the user site, observe bylaws.
If you touch components inside the DCP31, touch a grounded metal object to
discharge any static electricity from your body.
Otherwise, static electricity might damage the components.
After the power has been turned ON, the DCP31 does not operate for at least 15s.
Therefore, great care should be taken if the relay output from the controller is
used.
Correct settings appropriate for the type of the sensor are required. Since incor-
rect settings cause incorrect PV measurement, an unsafe situation like constant
100 % control output could occur.
