To ensure safe use, be sure to observe the following warnings and cautions.

NF Corporation 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 J S and EC

insulation standards.



Be sure to observe the contents of this instruction manual.

This instruction 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 instruction 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 Ω or lower) or higher.

The EC1000SA is automatically grounded when the 3-pin power plug is connected to a 3-pin power

outlet with a protective grounding contact.

This product does not come with a 3-pin to 2-pin conversion adapter. When using a separately sold

3-pin to 2-pin conversion adapter, be sure to connect the grounding wire of the adapter to the

grounding terminal next to the outlet.



Check the power suppl voltage.

This product operates on the power supply voltage indicated in Grounding and Power Supply

Connection in this instruction 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 anomal

f this product emits smoke, an abnormal smell, or abnormal noise, immediately power it off and

stop using it.

f such an anomaly occurs, do not use this product until it has been repaired, and immediately report

the problem to the location of purchase (either NF Corporation or our agent).



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 NF Corporation.



Do not modif this product.

Absolutely never modify this product, as this may cause new hazards and may disqualify this

product from repair in case of failure.



Do not expose this product to water

When this product is used in wet condition, it may cause an electric shock and a fire. f this product

is exposed to water, unplug the power cord immediately, and contact NF Corporation or one of our

agent.



If lightning occurs, power off this product and unplug the power cord

A lightning may cause an electric shock, a fire and a failure.



Prevention of electrical shock due to output voltage

The maximum output voltage of the EC1000SA is ±440 V.

Operate carefully the EC1000SA to avoid electrical shock.

Directly touching the output or changing cable connections while output is on may cause electrical

shock.
