“Exceeding Customer Expectations Through Performance Excellence"
The intention of this Tech Bulletin is to inform you that effective 07-21-2010 we have made some improvements in
the RAS-1000 for the Autocut and Ultracut units, this is in anticipation of the release of the 400 Amp system.
Some of the minor changes include a better connection for the negative cable and improved strain relieves, also the
new RAS-1000 can handle the 2/0 cable for the 400A system.
Going forward we will also use the 2/0 cable for the 300A systems, no longer requiring parallel the work and negative
cables.
For easy identifications the New RAS-1000 label will be marked as “
REMOTE ARC 400A” (Previous RAS units don’t have this mark)
Notes: 1. Previous RAS-1000 (without the 400A mark) cannot be used with 400 Amp systems.
2. This is an informative bulletin, No specific action is required at this time.
Please feel free to contact us if you have any questions
