EMC Safety Precautions
Prevent electromagnetic interference
To prevent electromagnetic interference, the instrument must be operated only when
closed and with all shielding covers fitted. Only suitable and shielded signal and control
cables may be used.
●
This applies particularly to cables that are connected to the rear or front panel.
Regardless of the data rate and the packet timing of the transport stream, high
signal levels can occur at individual points in the signal spectrum. To avoid EMC
problems, the cables should have at least 80 dB shielding protection up to 1 GHz.
This generally requires the use of cables with double shielding.
●
When wiring the LAN interface (10/100/1000 BASE-T), make sure that a suitable
cable (e.g. Category 5e) is used.
1.3.5 Connecting the Instrument to AC Power
The instrument is equipped with a universal power supply that accepts an AC voltage
range of 85 to 264 VAC at a frequency range of 47 to 63 Hertz. No external switching
or modification of the fuse is necessary. The AC power connector is at the rear of the
instrument.
●
Use the supplied AC power cable to connect the instrument to the AC power
supply. Since the instrument complies with safety class EN61010-1, it should only
be connected to a socket with a ground contact.
A standard EU power cord (with CEE 7/7 plug) is provided with every unit and if
the buyer is located outside the EU, a power cord compliant with safety regulations
for that location is supplied.
●
Use only the supplied detachable mains power cable or a properly rated
replacement cable.
●
Set the AC switch on the rear of the instrument to the I position.
1.3.6 AC Power Fuses
Before changing the fuses, switch off the instrument and disconnect it from the power
supply.
The instrument is equipped with one fuse (see section 6 of the User Manual). The fuse
is located beside the AC power switch (in the AC inlet) on the rear panel of the
instrument.
Changing the fuse:
●
Open the cover on the fuse box and remove the fuse holder.
