Safety Instructions for Lithium
Batteries
1 Safety Instructions for Lithium Batteries
The product contains exchangeable or built-in lithium polymer or lithium ion cells
or batteries. The use of the word battery in the following always means all types.
Only the battery contents are potentially hazardous. As long as a battery is
undamaged and the seals remain intact, there is no danger.
Impact, shock or heat can cause damage such as dents, punctures and other
deformations. A damaged battery poses a risk of personal injury. Handle a damaged or leaking battery with extreme care. Immediately ventilate the area since
the battery releases harmful gases. If you come into contact with the battery fluid,
immediately remove all contaminated clothing. Irritation can occur if the battery
fluid comes in contact with your skin or eyes. Immediately and thoroughly rinse
your skin or eyes with water and seek medical aid.
For safe handling, follow these rules:
●
Do not short-circuit the battery.
●
Do not mechanically damage the battery. Do not open or disassemble the battery.
●
Do not expose the battery to high temperatures such as open flames, hot surfaces and sunlight.
●
Only use the battery with the designated Rohde & Schwarz product.
●
Only use the appropriate Rohde & Schwarz charger to charge the batteries. If
the batteries are improperly charged, there is a risk of explosion. For charging
and discharging temperature ranges, see the product documentation.
●
Replace exchangeable batteries only with the same battery type.
●
Store the battery in the product or use the product packaging.
●
Dispose of exchangeable batteries separately from normal household waste
as specified by the local waste disposal agency.
If you disregard these rules, you risk serious personal injury or even death due to
explosion, fire or hazardous chemical substances. The product documentation
provides further details.
If exchangeable batteries or products with built-in batteries are defective, contact
the Rohde & Schwarz customer service. Rohde & Schwarz classifies the severity
of the defect. When returning batteries or Rohde & Schwarz products containing
batteries, use a carrier qualified to transport dangerous goods and notify the carrier of this classification. Follow the carrier’s transport stipulations in line with
IATA-DGR, IMDG-Code, ADR or RID.

2 DC power supply
Using the DC power supply (option R&S FSV‑B30), the instrument can be operated with a DC voltage of 10 V to 28 V. The voltage source can have a current of
25 A to 12.5 A.
If you use an external power supply unit to supply safety extra-low DC voltage
(SELV) to the instrument, 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. Use a cable no longer than 3 m.
2.1 Installing the DC power supply
The DC power supply is attached to the rear panel of the instrument.
To install the DC power supply on the instrument
Installing the DC power supply requires technically trained personnel.
1. Disconnect the DC power supply from the voltage source to avoid long-term
damage to the device.
2. Disconnect the power cable from the instrument.
3. Only for instruments with B1 option (ruggedized housing):

2.2 Connecting the DC cable
Use a voltage source with a DC voltage of 10 V to 28 V and a current of 25 A to
12.5 A. It is recommended that you fuse the voltage source with maximum 25 A.
1. Switch off the DC power supply to avoid long-term damage to the device.
2. NOTICE! Risk of instrument damage. Do not connect or disconnect the DC
cable to the DC power supply while the DC power supply is on. Connecting
the cable falsely or while the voltage source is powered can result in long-term
damage to the cable or the device.
Connect the supplied cable (6) to the DC power supply.

Storing and transporting batteries
3.4 Storing and transporting batteries
Safe handling of batteries is described in Chapter 1, "Safety Instructions for Lith-
ium Batteries", on page 3.
Keep the batteries clean and dry. If the terminals become soiled, clean them with
a dry, clean cloth.
Storing batteries
Ideally, store the batteries in the battery pack. Otherwise, observe the following
rules:
●
Prevent short-circuiting of the batteries, which can happen if batteries touch
each other or come into contact with metallic objects in the storage container.
As storage container, you can use the product packaging.
●
Do not expose to direct sunlight.
●
Store the batteries at room temperature.
●
Store the batteries at a state of charge between 50 % and 70 %.
Transporting products containing batteries
Products with built-in batteries or exchangeable batteries are dangerous goods
and have to be transported as such. Consider the requirements described in
Chapter 1, "Safety Instructions for Lithium Batteries", on page 3.
