Usage Precautions

Operating Environment

•Please use the ETH-100 only when the ambient temperature of the environment into which the unit is installed is within the following specified temperature limits:

Operation: -10 ∼ +50°C (+14 ∼ +122°F)

Storage: -40 ∼ +85°C (-40 ∼ +185°F)

•Avoid installation locations that may be subjected to large shocks or vibrations.

•Avoid installation locations that may be subjected to rapid changes in temperature or humidity.

Installation and Wiring

•Proper ground connections are vital for both safety and signal reliability reasons. Ensure that all electrical equipment is properly grounded.

•Route all communication cables separate from high-voltage or noise- emitting cabling (such as ASD input/output power wiring).

ASD Connections

•Do not touch charged parts of the drive such as the terminal block while the drive’s CHARGE lamp is lit. A charge will still be present in the drive’s internal electrolytic capacitors, and therefore touching these areas may result in an electrical shock. Always turn all drive input power supplies OFF, and wait at least 5 minutes after the CHARGE lamp has gone out before connecting communication cables.

•To avoid misoperation, do not connect any ETH-100 terminals to either the ASD’s E/GND terminals, the motor, or to any other power ground.

•When making common serial connections between the ETH-100 and ASDs, do not use cables that exceed 5 meters in length.

•For further drive-specific precaution, safety and installation information, please refer to the appropriate documentation supplied with your drive.

•Internal drive EEPROMs have a limited life span of write cycles. Observe all precautions contained in this manual and your ASD manual regarding which drive registers safely may and may not be repetitively written to.

•Because the ETH-100 derives its control power from the connected drives, removing power to all connected drives will also cause the ETH-100 to lose power.
