“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.
