Maintenance Chapter 6
Fuse Replacement Fast-acting fuses are included to protect the ProDySC in the event of a load short
circuit. If the screen is dark when power is applied, it may indicate a blown fuse.
Check the fuse(s) for continuity.
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.
