Safety Precautions

Be sure to securely connect the GL820's power cord.
●
After checking that the Power switch is turned off, connect
the power cord's female plug to the GL820 and then
connect its male plug into the electrical socket.
●
Use of the GL820 without the power cord securely plugged
into the electrical socket may result in electrical shock due
to current leakage.
●
Before running the GL820 using a DC power supply, be sure to
ground the protective ground terminal (
shock and fire hazards. For grounding, use a ground wire
with a diameter of at least 0.75 mm2. When using the GL820
in an environment where grounding is not possible, ensure
that the voltage to be measured is no greater than 50 V (DC
or rms).
Securely connect the power cord
Make sure that the socket has a
good protective ground
Before turning on the GL820, ensure that the electric
socket's supply voltage conforms to the GL820's power
rating.
●
Use of a different supply voltage may cause damage to the
GL820 or a fire hazard due
to electrical shock or current
leakage.

Avoid using the GL820 in extremely dusty or humid
places.
●
Such use may cause a fire hazard due to electrical shock or
current leakage.

Safety Precautions
WARNING
If the GL820 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 GL820 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.
) to avoid electrical
●
Never try to perform repair yourself. Repair work by
inexperienced personnel is
extremely dangerous.
Never disassemble or remodel the GL820.
●
Such action may cause a fire hazard due to electric shock or
current leakage.
●
Contact with a high-voltage component inside the GL820 may
cause electric shock.
●
If repair is required, contact your
sales representative or nearest
Graphtec vendor.
Avoid using the GL820 in places where it may be
exposed to water such as bathrooms, locations exposed
to wind and rain, and so on.
Avoid water
Never use a damaged power cord.
●
Use of a damaged cord may result in a fire hazard due to
electrical shock.
●
If the cord becomes damaged, order a new one to replace
it.
