Replacing Fuses
The power supply connector at the rear panel is protected by a fuse of type IEC60127
T1 L/H (IEC60127 T1.8 L/H on R&S
ZVA-Z500 converters). To replace the fuse, open
the fuse holder by slightly turning the lid counter-clockwise, preferably using a small
coin. A replacement fuse is provided with the instrument.
2.5
Maintenance
The frequency converter does not require any special maintenance. Make sure that the
air vents are not obstructed. The outside of the instrument is suitably cleaned using a
soft, line-free dust cloth.
Risk of instrument damage
Cleaning agents contain substances that can damage the instrument, e.g. solvent-con-
taining cleaning agents can damage the front panel labeling or plastic parts.
Never use cleaning agents such as solvents (thinners, acetone etc.), acids, bases or
other substances.

Storing and Packing
The converter can be stored at the temperature range quoted in the data sheet. When
stored for a longer period of time, it must be protected against dust.
Use the original packing to transport or dispatch the converter. In particular, use the
protective cap and the wooden box (see also
