Rear Panel Supply Switch
The rear panel Supply switch (Fig 10) is a 2-way rocker switch used to select between power on, and
standby.
When the Supply switch is set to the Standby position, dangerous voltage is still present in
the internal power supply circuitry. To ensure safe working, the drive assembly must be
isolated from the ac and dc input supplies.
