Safety Instructions
User Manual 1107.2470.12 - 03
E-6
Electric shock or fire hazard if the cross section of the connecting cables are too
small.
The operator, through consultation with an electrically skilled person, must ensure that
double-insulated connecting cables with a minimum cross section suitable for the
application are used.
The maximum power consumption of the device under test, the fuse rating of the
building installation and the cable length must be observed.
When installing the supplied cable sockets, the assembly instructions and the
requirements of the manufacturer must be observed
Since the permissible limit for the leakage current in line with EN 61010-1 as well as
the basic insulation for a device with degree of protection class I cannot be met due to
the required standard-compliant setup in line with CISPR 16-1-2 (EN 55016-1-2),
additional measures must be taken to protect the user against direct or indirect contact.
The operator is responsible for ensuring that protective measures in line with VDE
0100-410 (IEC 60364-4-41) are maintained while working with the V-network. Prior to
putting the V-network into operation, a secure connection must be made with the
protective conductor available on site. This connection must fully meet the
requirements for protective conductor connections. The connection must not be
opened until the V-network has been definitively disconnected from the mains supply.
It must be assumed that, when connecting with a flexible cable, the ground wire
connection can come loose. Before commissioning, the V-network must therefore be
connected with an additional protective conductor according to VDE 0100-540 Part 5-
54 (IEC 60364-5-54) with a sufficient cross section between the protective earth
connection of the measurement room and the rear panel protective earth conductor
terminal
(
) of the R&S ENV4200.
Only then may the V-network be connected to the mains supply. Removal from service
must be performed in the reverse order: First disconnect the V-network from the mains
supply and only then disconnect the additional protective conductor connection.
If "electrical separation" is used as a protective measure, an electrical specialist must
decide at which points a ground connection or a connection to the protective earth
terminal available on site may be made.
In general, when the R&S ENV4200 is operated, make sure that the air supply is not
obstructed from above or below. Since the device has air vents located on the bottom
side, it must be placed upon a nonflammable base (e.g. metal plate) in order to prevent
a fire if the ventilation system fails.
