2.6.1 Cleaning
The outside of the instrument is suitably cleaned using a soft, lint-free dust cloth.
Shock hazard
Before cleaning the instrument, make sure that the instrument is switched off and dis-
connected from all power supplies.
Instrument damage caused by cleaning agents
Cleaning agents contain substances that may damage the instrument, e.g. cleaning
agents that contain a solvent may damage the front panel labeling or plastic parts.
Never use cleaning agents such as solvents (thinners, acetone, etc.), acids, bases, or
other substances.
Risk of instrument damage due to obstructed fans
If the instrument is operated in dusty areas, the fans may become obstructed by dust or
other particles in the process of time. Make sure to check and, if necessary, clean the
fans regularly to ensure they operate properly at all times. If the instrument is run with
obstructed fans for a longer period, it may become overheated which may cause damage.
2.6.2 Storing and Packing
The storage temperature range of the instrument is given in the data sheet. If the instru-
ment is to be stored for a longer period of time, it must be protected against dust.
Repack the instrument as it was originally packed when transporting or shipping. If the
original packing is no longer available, use a sturdy cardboard box of suitable size. Wrap
antistatic packing foil around the instrument to protect it from electrostatic charging. Pro-
vide for sufficient padding to protect the instrument against mechanical damage.
2.6.3 Replacing Fuses
The instrument is protected by two fuses located in the fuse holder to the right of the AC
power switch on the rear panel.
Type of fuses: T10 IEC 127-2/V, stock no. 0606.3136.00
