ENV216 Operating Manual
3560.6550.12 -01- 1.1 E-1
1 Safety directions
Note
Since the standard-compliant configuration required by CISPR 16 and VDE 0876
means that it is not possible to limit the leakage current to the value permitted by
EN61010-1, and the base insulation required for a category I protection device can-
not be assured, it is imperative to provide additional measures safeguarding against
direct or indirect contact by the user.
The operator is responsible for ensuring that protection in accordance with VDE0100
Part 410 and VDE0876 Part 1 is maintained during work with the line impedance
stabilization network. Before using for the first time, a secure connection must be
made to the location's grounding conductor. This connection must satisfy the re-
quirements for a grounding conductor connection in every detail. It must not be re-
moved until after the network has been disconnected from the mains power supply.
If the "fuse disconnector" protection method is used, a qualified electrical engineer
must indicate the points where grounding or a connection to the location's grounding
conductor may be sited.
The safety notes in the accompanying operating instructions and on the outside of
the device must be followed at all times.
Caution!
Before using for the first time, the network must be connected to an additional con-
ductor that is compliant with VDE0100.
Users must be aware that it is possible for socket connections and grounding con-
ductors to become disconnected. A further grounding conductor with adequate
cross-section must be connected between a grounding conductor connection for the
measurement area and the grounding conductor connection (grounding bolt) on the
back panel of the ENV216.
Only then may the network be connected to the mains power supply.
At shutdown, the same procedure must be followed in the reverse order:
First the network must be disconnected from the mains power supply, and only then
should the additional grounding conductor connection be removed.
