Approvals
Instruments with approvals can have different technical data depending on the version.
That's why the associated approval documents have to be noted with these instruments. They are
part of the delivery or can be downloaded under www.vega.com via "VEGA Tools" and "serial
number search" as well as via "Downloads" and "Approvals".
9)
The prerequisites for maintaining the protection rating are a suitable cable
as well as correct mounting.
