Usage Precautions
• Please use the gateway 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
tem
p
erature or humidit
y
.
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 gateway terminals to either
the ASD’s E/GND terminals, the motor, or to any other power ground.
• When making common serial connections between the gateway and
Toshiba 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 ASD 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.
• When used without an Auxiliary power source (Toshiba ASD common
serial mode), the gateway derives its control power from the connected
drives. Therefore, removing power to all connected drives will also
cause the gateway to lose power.
