Risk of electric shock
Insufficient insulation and exceeding the current limitation of external power supplies
for safety extra-low DC voltage (SELV) can lead to electric shock.
Be sure to meet the requirements for reinforced/double insulation in accordance with
DIN/EN/IEC 61010 (UL 3111, CSA C22.2 No. 1010.1) or DIN/EN/IEC 60950 (UL 1950,
CSA C22.2 No. 950). Provide current limitation in accordance with DIN EN 61010-1
Appendix F2.1.
DC Connection
► Connect the DC power supply on the rear panel of the R&S
ZNL to the power
source using the supplied power cable.
5.1.1.7
Connecting an Optional Battery Pack (R&S
FPL1-B31)
As an alternative to the fixed AC or DC power supply, the R&S
ZNL can be operated
by a battery pack if the option R&S
FPL1-B31 is installed. If the battery pack is instal-
led and neither DC nor AC power is supplied, the R&S
ZNL automatically switches to
battery operation (during operation).
This option is not available for the R&S
ZNLE.
The R&S
ZNL comes with the battery pack already installed if the battery option was
ordered together with the instrument. Otherwise, insert the battery packs in the slots at
the top of the rear panel.
The battery pack is charged directly in the R&S
ZNL via the common AC or DC power
supply. The battery pack can be charged at an ambient temperature b0
°C
and +45
°C. If the temperature is above or below these values, charging is interrupted.
If the battery temperature rises above +53
°C, charging is stopped.
When the battery is being charged in standby mode, the [Power] LED blinks. During
operation, the status bar indicates that the battery is being charged.
