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.
