Safety Precautions
WARNING
Be sure to securely connect the WR300 Series power cord.
• After checking that the Power switch is turned off, connect the power cord's
female plug to the WR300 Series and then connect its male plug into the
electrical socket.
• Use of the WR300 Series without the power cord securely plugged into the
electrical socket may result in electrical shock due to current leakage.
• Before running the WR300 Series using a DC power supply, be sure to
ground the protective ground terminal (
) to avoid electrical shock and
fire hazards. For grounding, use a ground wire with a diameter of at least
0.75 mm
2
.
When using the WR300 Series in an environment where grounding is not
possible, ensure that the voltage to be measured is no greater than 50 V
(DC or rms).
If the WR300 Series generates smoke, is too hot, emits a strange odor, or otherwise functions abnormally,
turn off its power and unplug its power cord from the electrical socket.
• Use of the WR300 Series in such status may result in a fire hazard or
electrical shock.
•After checking that smoke is no longer being generated, contact your sales
representative or nearest Graphtec vendor to request repair.
•Never try to perform repair yourself. Repair work by inexperienced
personnel is extremely dangerous.
Before turning on the WR300 Series, ensure that the electric socket's supply voltage conforms to the
WR300 Series power rating.
• Use of a different supply voltage may cause damage to the WR300 Series
or a fire hazard due to electrical shock or current leakage.
Never disassemble or remodel the WR300 Series.
• Such action may cause a fire hazard due to electric shock or current
leakage.
• Contact with a high-voltage component inside the WR300 Series may
cause electric shock.
• If repair is required, contact your sales representative or nearest Graphtec
vendor.
Avoid using the WR300 Series in extremely dusty or humid places.
• Such use may cause a fire hazard due to electrical shock or current
leakage.
