2.3.3 Connecting the R&S UPV 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; the input voltage at the con-
nectors of the analog analyzers should not exceed 110 V (effective, sinusoidal) and
160 V (peak value). Do not use the instrument in measuring categories 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.
The AC supply connector socket is at the rear of the instrument. The instrument can be
set up for connection to AC supply systems of 100
V, 120
V, 220
V and 230
V and can
be operated with ±10 % tolerance and an AC supply frequency of 47
Hz to 63
Hz. The
instrument is also suitable for operation with power supply systems with the other nom-
inal voltages specified in the table below
