Event Description
Event Resolution
WARNING: Turn the power to the ProDySC off by placing the Bypass Switch into “BYPASS” or opening the branch circuit
breaker before replacing the fuse. Failure to comply with this warning can result in injury or death.
The ProDySC has high voltage remaining up to 5 minutes after disconnection from the AC line. Touching exposed or
disconnected terminals, cables or parts of the ProDySC can lead to serious injuries or even death. Wait for a minimum of 5
minutes before performing any service or testing on the DySC after power is removed.
Keep the cabinet doors closed to ensure proper cooling airflow and to protect personnel from dangerous voltages inside
the ProDySC.
IMPORTANT
A qualified electrician must replace the fuse. Open the front cabinet door(s) to access the fuse holders and fuses.
To maintain protection of the ProDySC, be sure to replace the fuse with the same type and rating. These fuses are
available from the factory. Provide the factory with the ProDySC model number located on the outside of the enclosure.
