2.3.2.2 Rack installation
A rack adapter (refer to data sheet for Order No.) is required for installation in a 19"
rack. The mounting instructions are supplied with the adapter.
Possible damage to the instrument from overheating
Restricted airflow at the side wall openings can cause the instrument to overheat.
To ensure sufficient air supply, all fan openings must be clear and the airflow at the
openings of the side walls must not be impeded. The distance to the wall must be at
least 10 cm.
2.3.3 Connecting the R&S UPP to the AC Supply
Possible damage to the instrument
Before connecting and switching on the instrument, observe the following items to
avoid any damage to the instrument:
●
The tube for the housing has to be attached and screwed in place.
●
The ventilation openings must be clear; ensure that air can freely exit at the holes
on the sides. The minimum distance to the wall should therefore be at least 10 cm.
●
The instrument must be dry.
●
The instrument should only be operated in the horizontal position on an even sur-
face.
●
The ambient temperature must not exceed the range specified in the data sheet.
●
It must be ensured that none of the voltage levels at the inputs exceed permissible
limits.
●
The instrument complies with measuring category I; make sure that the input volt-
age at the connectors of the analog analyzers does not exceed 50 V (effective,
sinusoidal) and 70 V (peak value). Do not use the instrument in measuring catego-
ries II, III and IV.
Explanation:
Measuring circuits as defined in section 6.7.4 of EN61010-1
Measuring category I is intended for measurements on circuits which are not con-
nected to the high-voltage current system.
●
The outputs of the instrument should not be overloaded and correct polarity must
be ensured.
