Power
Be sure to check the power supply voltage before turning on the power.
Grounding
Be sure to connect a Class D (100
V
or less) ground before turning on the power, to
minimize the possibility of shock.
Need for Grounding
Do not cut the internal or external protective ground wire, or remove the ground wire
from the terminal. This creates a shock hazard.
Do not Operate without Protective Grounding and Fuse
Do not operate the instrument without protective grounding and correct fuse.
Fuse
For safety, this product is fused internally. It is recommended that you ask the local
service representative to change the fuse; do not either change it yourself, or open the
case to check the fuse. Turn off the power switch and disconnect the instrument from
the power before changing the fuse. Do not use a fuse of different type or size, or short-
circuit the fuse holder.
