damage to this product.
WARNING
Do not use this device in an environment with conductive pol-
lution, or with dry non-conductive pollution which can become
conductive due to condensation, etc. Otherwise, problems such
as tracking phenomena may damage parts, resulting in fire.
Be sure to use the fuse described in the specifications for the
power wiring of this device. Otherwise, tracking phenomena or
parts failure due to other factors may cause fire.
Note that incorrect wiring of the SDC25/26 can damage the
SDC25/26 and lead to other hazards. Check that the SDC25/26 has
been correctly wired before turning the power ON.
Before wiring, or removing/mounting the SDC25/26, be sure to
turn the power OFF.
Failure to do so might cause electric shock or faulty operation.
Do not touch electrically charged parts such as the power termi-
nals. Doing so might cause electric shock.
WARNING
Do not disassemble the SDC25/26.
Doing so might cause electric shock or faulty operation.
CAUTION
Use the SDC25/26 within the operating ranges recommended
in the specifications (temperature, humidity, voltage, vibration,
shock, mounting direction, atmosphere, etc.).
Failure to do so might cause fire or faulty operation.
Do not block ventilation holes.
Doing so might cause fire or faulty operation.
Wire the SDC25/26 properly according to predetermined stan-
dards. Also wire the SDC25/26 using specified power leads accord-
ing 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 controller
case. Doing so might cause fire or faulty operation.
Firmly tighten the terminal screws at the torque listed in the speci-
fications. Insufficient tightening of terminal screws might cause
electric shock or fire.
Do not use unused terminals on the SDC25/26 as relay terminals.
Doing so might cause electric shock, fire or faulty operation.
We recommend attaching the terminal cover (sold separately)
after wiring the SDC25/26.
Failure to do so might cause electric shock.
Use the relays within the recommended service life.
Failure to do so 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.
Do not operate the keys with a propelling pencil or sharp-tipped
object. Doing so might cause faulty operation.
