Safety Precautions 
To ensure safe use, be sure to observe the following warnings and cautions.
Good Will shall not be held liable for damages that arise from a failure to observe these warnings and
cautions.
This product is a Class 1 product (with protective conductor terminal) that conforms to the JIS and IEC
insulation standards.
Be sure to observe the contents of this user manual.
This user manual contains information for the safe operation and use of this product.
Be sure to read this information first before using this product.
All the warnings in the user manual must be heeded to prevent hazards that may cause major
accidents.
Be sure to ground the product.
This product uses a line filter and must be grounded to avoid the risk of electric shock.
To prevent electric shock, be sure to safely implement grounding according to Japanese Standard
for Electrical Equipment Technology D (100 or lower) or higher.
The APS-1102 is automatically grounded when the 3-prong power plug is connected to a 3-prong
power outlet with a protective grounding contact.
This product does not come with a 3-prong to 2-prong conversion adapter. When using a separately
sold 3-prong to 2-prong conversion adapter, be sure to connect the grounding wire of the adapter to
the grounding terminal next to the outlet.
Check the power supply voltage.
This product operates on the power supply voltage indicated in Grounding and Power Supply
Connection in this user manual.
Prior to connecting the power supply, check that the voltage of the power supply matches the rated
power supply of the product.
In case of suspected anomaly
If this product emits smoke, an abnormal smell, or abnormal noise, immediately power it off and
stop using it.
If such an anomaly occurs, do not use this product until it hasbeen repaired, and immediately report
the problem to the location of purchase (either Good Will or your distributor).
Do not use this product when gas is present.
An explosion or other such hazard may result.
Do not remove the cover.
This product contains high-voltage parts. Absolutely never remove its cover.
Even when the inside of this product needs to be inspected, do not touch the inside. All such
inspections are to be performed by service technicians designated by Good Will.
Do not modify this product.
Absolutely never modify this product, as this may cause new hazards and may disqualify this
product from repair in case of failure.

Prevention of electrical shock due to output voltage
The maximum output of the APS-1102 is 400 V.
Carefully operate the APS-1102 to avoid electrical shock.
Directly touching the output or changing cable connections while output is on may cause electrical
shock.
Safety-related symbols
The general definitions of the safety-related symbols used on this product and in the user manual
are provided below.
User Manual Reference Symbol
This symbol is displayed to alert the user to potential danger and refer
him/her to the user manual.
Electric Shock Danger Symbol
This symbol indicates locations that present a risk of electric shock under
specific conditions.
Protective Ground-Terminal Symbol
This symbol identifies a pin that must be grounded to avoid electric shock.
Before operating the device, be sure to safely implement grounding
according to Japanese Standard for Electrical Equipment Technology D
(Type 3, 100 or lower) or higher.
Warning Symbol
This symbol indicates information for avoiding danger to human life or bodily
injury while handling this product.
Caution Symbol
This symbol indicates information for preventing damage to the product
when handling it.
Other symbols
This symbol indicates the “on” position of the power switch.
This symbol indicates the “off” position of the power switch.
This symbol indicates that the external conductor of the connector is connected to
the case.
This symbol indicates that the external conductor of the connector is connected to
the signal ground.
