POWER SUPPLY
Make sure that the power supply is within the rating. If any voltage exceeding the rated
voltage was supplied, there would be risk of damage to this amplifier, or even a fire. Also, in
order to prevent electric shock and hazards such as a fire, be sure to use only the AC power
cable and the adapter (3-prong/2-prong converter) supplied with this amplifier.
●
Protective Grounding
Be sure to ground this amplifier before supplying power. Grounding is necessary to use this
amplifier safely, as well as to protect the user and peripheral equipment from injury or
damage. Be sure to observe the following instructions:
1) Protective grounding
This product uses a 3-pole power cable, which has grounding. Always connect to the power
outlet having grounding. If using 3-prong/2-prong adapter, secure the grounding by
connecting either a protective terminal or a grounding lead extending from the adapter.
2) Caution on protective function
While the power is supplied to the amplifier, do not cut or remove the protective grounding
line. Otherwise, safety of the amplifier is not guaranteed.
3) Protective function failure
Avoid using this product when there is a failure in protective grounding or protective
functions. Confirm that there is no failure in the protective function before using.
●
Use in Gaseous Atmosphere
Never use this amplifier in a flammable or explosive atmosphere, or atmosphere of steam. Use
in such atmosphere will result in danger to users and the amplifier.
●
Disassembling the Frame
It is dangerous to remove the frame. Do not remove the frame from the amplifier other than
100VAC/200VAC switching using the selection switch.
●
Input Signal Connection
Connect the signal wire to the input terminal after connecting protective grounding terminal
to the ground. Please work after confirming that the signal and the common mode voltage are
not impressed to the input line when you connect the input line to prevent the shock hazard
and the accident of damaging by a fire.
●
Note in operation
There is a possibility that high voltage is caused in the working of this product between the
input terminal (Input signal line) and this unit (protective grounding), or between the input
terminal and output (output signal line), etc. Therefore, please be careful enough on the
electric shock hazard with the operation.
