Installation method
Follow the guidance below on how to use this device to guarantee satisfactory safety
and performance.
- Keep the cabinet door of the device closed.
- Confirm that all the empty slots in the cabinet are covered by dummy covers.
- Confirm that all cables are firmly secured with the screws.
- Install rack type devices in the cabinet and lock the cabinet doors for safety.
- Prepare a dedicated circuit breaker in the same room of the device so that it can be
used to cut off the power supply when abnormality occurs. Use this breaker to
shutdown power supply to equipment devices when a device abnormality occurs.
Use a breaker that meets STARDOM power supply specification requirements.
