Power Supply
Make sure that the power supply is within the rating. If any voltage exceeding the rated voltage were
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 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 is provided with grounding. Always connect to the
power outlet having grounding.
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 amplifiers.
Input Signal Connection
Connect the signal wire to the input terminal after connecting protective grounding terminal to
the ground. When connecting the signal wire, check whether the signal wire is being properly
protected from leak signals from the environment or common-mode voltage in order to avoid
electrical shock or burning. Note that the AS2503 does not have isolation between the input
block and output block.
Cautions during Operation
Be careful of operations because large voltage might be applied between the input terminal (input
signal wire) and ground of this amplifier or input terminal and output terminal (output signal wire).
Installation Category and Contamination Level
The AS series amplifiers are devices with Installation Category II and Contamination Level II.
Use them following the regulations defined in Installation Category II and Contamination Level II.
