Risk of instrument damage due to insufficient airflow in a rack
If you mount several instruments in a rack, you need an efficient ventilation
concept to ensure that the instruments do not overheat. Insufficient airflow
for a longer period can disturb the operation and even cause damage.
4.1.4 Connecting the AC Power
The R&S ZNLE is equipped with an AC power supply connector. The R&S ZNLE
can be used with different AC power voltages and adapts itself automatically to it.
Refer to the datasheet for the requirements of voltage and frequency. The AC
power connector is located on the rear panel of the instrument.
For details on the connector, refer to Chapter 5.2.1, "AC Power Supply Connec-
tion and Main Power Switch", on page 44.
► Connect the R&S ZNLE to the AC power supply using the supplied power
cable.
Since the instrument is assembled in line with the specifications for safety
class EN61010, it must only be connected to an outlet that has a ground con-
tact.
4.1.5 Switching the Instrument On and Off
Switching on the instrument
1. Press the AC power switch on the rear panel to position "I".
2. Press the [Power] key on the front panel of the instrument.
The instrument operates on DC or AC power, whichever is supplied. After
booting, the instrument is ready for operation. The green [POWER] LED indi-
cates this.
A steady orange LED indicates the instrument is in standby mode.
