Safety Precautions - GRAPHTEC GL450 User Manual

Safety Precautions

Be sure to securely connect the GL450's power cord.
• After checking that the Power switch is turned off, connect the power cord's
female plug to the GL450 and then connect its male plug into the electrical
socket.
• Use of the GL450 without the power cord securely plugged into the
electrical socket may result in electrical shock due to current leakage.
• Before running the GL450 using a DC power supply, be sure to ground the
protective ground terminal (
For grounding, use a ground wire with a diameter of at least 0.75 mm
When using the GL450 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 GL450 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 GL450 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 GL450, ensure that the electric socket's supply voltage conforms to the GL450's
power rating.
• Use of a different supply voltage may cause damage to the GL450 or a fire
hazard due to electrical shock or current leakage.
Never disassemble or remodel the GL450.
• Such action may cause a fire hazard due to electric shock or current
leakage.
• Contact with a high-voltage component inside the GL450 may cause
electric shock.
• If repair is required, contact your sales representative or nearest Graphtec
vendor.
Avoid using the GL450 in extremely dusty or humid places.
• Such use may cause a fire hazard due to electrical shock or current
leakage.
