Safety Precautions

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

Yokogawa Meters & Instruments Corporation shall not be held liable for damages that arise from

a failure to observe these warnings and cautions.

This product is a Class I product (with protective conductor terminal) that conforms to the JIS and

IEC insulation standards.

●Use the Instrument Only for Its Intended Purpose

The FG410/FG420 is designed to generate sine waveforms, rectangular waveforms, and

other various types of voltage waveforms. Use the FG410/FG420 only for this purpose.

●Check the Physical Appearance

Do not use the instrument if there is a problem with its physical appearance.

●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 such that ground resis-

tance is 100 Ω or lower.

The FG410/FG420 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 (green)

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 shown in 2.3 Grounding and Power

Supply Connection in the Basics 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 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 has been repaired, and

immediately report the problem to the location of purchase (either YOKOGAWA 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 YOKOGAWA.

●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.

●Install or Use the Instrument in Appropriate Locations

• This instrument is designed to be used indoors. Do not install or use it outdoors.

IV IM FG410-01EN

• Install the instrument so that you can immediately remove the power cord if an abnormal

or dangerous condition occurs.

●Safety-related symbols

The general definitions of the safety-related symbols used on this product and in the

instruction manual are provided below.

Instruction Manual Reference Symbol

This symbol is displayed to alert the user to potential danger and refer

him/her to the instruction manual.

Electric Shock Danger Symbol

This symbol indicates locations that present a risk of electric shock under

specific conditions.

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 that the external conductor of the connector is

connected to the case.

This symbol shows that the external conductor of the connector is

insulated from the case.

It shows, however, that the potential difference from the grounding

potential is restricted to 42 Vpk or lower for safety. (Since this product is

grounded when used, the potential of the case equals the grounding

potential.)

●Waste disposal

To help ensure environmental protection, use a professional industrial waste contractor to

dispose of this product. A battery is not used for this product.
