Usage Precautions
Operating Environment
•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:
Storage:
•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
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 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
•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.
