SFQ Putting into Operation
1.2 Putting into Operation
see also section 1.1, Legend for Front and Rear View
Prior to putting the instrument into operation make sure that
• the setting for the available AC supply voltage is correct (see section 1.3.1),
• signal levels applied to the inputs do not exceed permissible limits,
• the instrument is operated within the permissible temperature range (permissible ambient
temperature range +5°C to +45°C),
• the fan at the rear of the instrument is not obstructed (to prevent overheating of the unit),
• the outputs of the instrument are not overloaded or wrongly connected.
Warning:
Input voltages above permissible limits (see data sheet) may cause the instrument to
be damaged.
1.2.1 Positioning the Instrument
The instrument is equipped with feet that can be folded out at the instrument front to f acilitate operation.
To do so lift up the instrument at the front and swing down the feet.
The instrument is constructed so that its operating temperature remains sufficiently low even in
continuous operation. When the unit is used as a benchtop make sure that the air vents are not
obstructed to prevent the instrument being overheated - especially during continuous operation.
Sufficient ventilation must also be ensured when the unit is rackmounted. .
1.2.2 EMC Safety Precautions
Warning:
To prevent electromagnetic interference the ins trument should be operated closed and
with all screening covers fitted. Take the appropriate measures when calibrating the
open instrument. Make sure that only suitable, screened IEC/IEEE-bus cables are used.

1.3 Connecting the Instrument
1.3.1 AC Supply Connection
The instrument m ay be operated at 90 V to 132 V and 180 V to 265 V AC at frequencies from 47 Hz to
440 Hz. The AC supply connector is at the rear of the unit. T he inst rument automatically sets its elf to the
applied voltage by selecting one of the two permissible voltage ranges. Adjusting the instrum ent to a
particular AC supply voltage is therefore not required.
When the instrum ent is switched off, an "O" is visible above the power switch which may be on for any
period of time. The ins trument need only be switched off when it is to be c ompletely disconnected f rom
the AC supply.
