Safety Instructions
These operating instructions are part of the device and must be available to the
operating personnel at all times. All safety instructions and remarks must be observed.
The R&S ENV4200 complies with Measurement Category CAT II according to
IEC 61010-2-30.
Electric shock in case of wrong connection order.
The protective earth (PE) connection for the V-network must not be removed until all
other connections have been disconnected.
Put the V-network into operation in the following order (
connect additional PE first
):
1.
Connect V-network to additional protective earth.
2.
Connect network to power supply network.
Take the V-network out of operation in the following order (
disconnect additional PE
last
):
1.
Disconnect V-network from mains supply.
2.
Disconnect V-network from additional protective earth.
All safety instructions and warnings given on the device and in this manual must be
strictly observed.
Incorrect operation of the V-network may expose users to a life-threatening electric
shock.
Users must receive suitable technical training.
Electric shock due to improper operation.
By design, V-networks exhibit high leakage currents. Moreover, by principle, such a
device does not have standard-compliant isolation and there is no fuse in the
measuring circuit (the R&S ENV4200 only has a fuse in the auxiliary circuit of the
ventilation system). Hence, users must be protected against touching conductive parts
that may carry live mains voltage.
To ensure this, the V-network must be put into operation only by qualified electrical
specialists. The applicable national regulations and standards must be observed as
part of the installation process.
