Approvals
Instruments with approvals can have different technical data depending on the version.
For that reason the associated approval documents of these instruments must be carefully noted.
They are part of the delivery or can be downloaded under www.vega.com and "VEGA Tools" as
well as under "Downloads" and "Approvals".
6) The prerequisites for maintaining the protection rating are a suitable cable as well as correct mounting.
