Usage Precautions
• 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.
Operating Environment
• 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).
Installation and Wiring
• 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.
