or other 500 series module power racks. To take full advantage of the unique features that 
have been incorporated, please read through this manual before using it. This will give you 
a broader sense of its capabilities. If you have questions that are not covered in this manual, 
please visit the FAQ section on our website. This is where we post answers to questions from 
users. If you cannot fi nd the answer to your question please feel free to send an email to 
[email protected] and we will do our very best to respond as quickly as possible.

The Radial PowerPre 500 is warm, accurate and noise free. Enjoy. 

 

WARNING NOTICE TO USER!

Although preventative safety measures have been designed into Radial 500 series 
products 

we strictly advise against hot-swapping modules

 or plugging and 

unplugging them when the Workhorse or other 500 series rack is powered on. Hot 
swapping can cause connection sparks at the card-edge connector that could send 
damaging transients to other equipment. This also greatly reduces the life span of the 
contacts. Damage due to hot swapping is not covered under warranty.  There are no 
user serviceable parts inside.
