Safety Instructions
4. If products/components are mechanically and/or thermically processed in a manner that goes beyond their intended use, hazardous substances (heavy-metal dust such as lead, beryllium, nickel) may be released. For this reason, the product may only be disassembled, e.g. for disposal purposes, by specially trained personnel. Improper disassembly may be hazardous to your health. National waste disposal regulations must be observed.
5. If handling the product yields hazardous substances or fuels that must be disposed of in a special way, e.g. coolants or engine oils that must be replenished regularly, the safety instructions of the manufacturer of the hazardous substances or fuels and the applicable regional waste disposal regulations must be observed. Also observe the relevant safety instructions in the product documentation.
6. Depending on the function, certain products such as RF radio equipment can produce an elevated level of electromagnetic radiation. Considering that unborn life requires increased protection, pregnant women should be protected by appropriate measures. Persons with pacemakers may also be endangered by electromagnetic radiation. The employer/operator is required to assess workplaces where there is a special risk of exposure to radiation and, if necessary, take measures to avert the danger.
7. Operating the products requires special training and intense concentration. Make certain that persons who use the products are physically, mentally and emotionally fit enough to handle operating the products; otherwise injuries or material damage may occur. It is the responsibility of the employer to select suitable personnel for operating the products.
8. Prior to switching on the product, it must be ensured that the nominal voltage setting on the product matches the nominal voltage of the AC supply network. If a different voltage is to be set, the power fuse of the product may have to be changed accordingly.
9. In the case of products of safety class I with movable power cord and connector, operation is permitted only on sockets with earthing contact and protective earth connection.
10. Intentionally breaking the protective earth connection either in the feed line or in the
product itself is not permitted. Doing so can result in the danger of an electric shock from the product. If extension cords or connector strips are implemented, they must be checked on a regular basis to ensure that they are safe to use.
11. If the product has no power switch for disconnection from the AC supply, the plug of the connecting cable is regarded as the disconnecting device. In such cases, it must be ensured that the power plug is easily reachable and accessible at all times (corresponding to the length of connecting cable, approx. 2 m). Functional or electronic switches are not suitable for providing disconnection from the AC supply. If products without power switches are integrated in racks or systems, a disconnecting device must be provided at the system level.
12. Never use the product if the power cable is damaged. Check the power cable on a regular basis to ensure that it is in proper operating condition. By taking appropriate safety measures and carefully laying the power cable, ensure that the cable cannot be damaged and that no one can be hurt by e.g. tripping over the cable or suffering an electric shock.
13. The product may be operated only from TN/TT supply networks fused with max. 16 A (higher fuse only after consulting with the Rohde & Schwarz group of companies).
14. Do not insert the plug into sockets that are dusty or dirty. Insert the plug firmly and all the way into the socket. Otherwise, this can result in sparks, fire and/or injuries.
15. Do not overload any sockets, extension cords or connector strips; doing so can cause fire or electric shocks.
16. For measurements in circuits with voltages V
> 30 V, suitable measures (e.g.
rms
appropriate measuring equipment, fusing, current limiting, electrical separation, insulation) should be taken to avoid any hazards.
17. Ensure that the connections with information technology equipment comply with IEC 950/EN 60950.
18. Unless expressly permitted, never remove the cover or any part of the housing while the product is in operation. Doing so will expose circuits and components and can lead to injuries, fire or damage to the product.

19. If a product is to be permanently installed, the connection between the PE terminal on site and the product's PE conductor must be made first before any other connection is made. The product may be installed and connected only by a license electrician.
20. For permanently installed equipment without built-in fuses, circuit breakers or similar protective devices, the supply circuit must be fused in such a way that suitable protection is provided for users and products.
21. Do not insert any objects into the openings in the housing that are not designed for this purpose. Never pour any liquids onto or into the housing. This can cause short circuits inside the product and/or electric shocks, fire or injuries.
22. Use suitable overvoltage protection to ensure that no overvoltage (such as that caused by a thunderstorm) can reach the product. Otherwise the operating personnel will be endangered by electric shocks.
23. Rohde & Schwarz products are not protected against penetration of water, unless otherwise specified (see also safety instruction 1.). If this is not taken into account, there exists the danger of electric shock for the user or damage to the product, which can also lead to personal injury.
24. Never use the product under conditions in which condensation has formed or can form in or on the product, e.g. if the product was moved from a cold to a warm environment.
25. Do not close any slots or openings on the product, since they are necessary for ventilation and prevent the product from overheating. Do not place the product on soft surfaces such as sofas or rugs or inside a closed housing, unless this is well ventilated.
26. Do not place the product on heat­generating devices such as radiators or fan heaters. The temperature of the environment must not exceed the maximum temperature specified in the data sheet.
27. Batteries and storage batteries must not be exposed to high temperatures or fire. Keep batteries and storage batteries away from children. Do not short-circuit batteries and storage batteries. If batteries or storage batteries are improperly replaced, this can cause an explosion (warning: lithium cells). Replace
the battery or storage battery only with the matching Rohde & Schwarz type (see spare parts list). Batteries and storage batteries must be recycled and kept separate from residual waste. Batteries and storage batteries that contain lead, mercury or cadmium are hazardous waste. Observe the national regulations regarding waste disposal and recycling.
28. Please be aware that in the event of a fire, toxic substances (gases, liquids etc.) that may be hazardous to your health may escape from the product.
29. The product can be very heavy. Be careful when moving it to avoid back or other physical injuries.
30. Do not place the product on surfaces, vehicles, cabinets or tables that for reasons of weight or stability are unsuitable for this purpose. Always follow the manufacturer's installation instructions when installing the product and fastening it to objects or structures (e.g. walls and shelves).
31. Handles on the products are designed exclusively for personnel to hold or carry the product. It is therefore not permissible to use handles for fastening the product to or on means of transport such as cranes, fork lifts, wagons, etc. The user is responsible for securely fastening the products to or on the means of transport and for observing the safety regulations of the manufacturer of the means of transport. Noncompliance can result in personal injury or material damage.
32. If you use the product in a vehicle, it is the sole responsibility of the driver to drive the vehicle safely. Adequately secure the product in the vehicle to prevent injuries or other damage in the event of an accident.

1 Safety directions
Note
Since the standard-compliant configuration required by CISPR 16 and VDE 0876 means that it is not possible to limit the leakage current to the value permitted by EN61010-1, and the base insulation required for a category I protection device can­not be assured, it is imperative to provide additional measures safeguarding against direct or indirect contact by the user.
The operator is responsible for ensuring that protection in accordance with VDE0100 Part 410 and VDE0876 Part 1 is maintained during work with the line impedance stabilization network. Before using for the first time, a secure connection must be made to the location's grounding conductor. This connection must satisfy the re­quirements for a grounding conductor connection in every detail. It must not be re­moved until after the network has been disconnected from the mains power supply.
If the "fuse disconnector" protection method is used, a qualified electrical engineer must indicate the points where grounding or a connection to the location's grounding conductor may be sited.
The safety notes in the accompanying operating instructions and on the outside of the device must be followed at all times.
Caution!

ENV216 Operating Manual
2 Brief introduction
Introduction
The ENV216 compact Two Line V-Network is used to measure noise voltage on mains-dependent con­sumers.
Its principal tasks are:
• To supply the equipment under test with mains voltage
• To provide a standardized load impedance
• Defined transmission of the noise voltage generated by the equipment under test to the EMI test
receiver
• Isolation of the test circuit from interference of the power source.
The ENV216 Two Line V Network is constructed using air-core inductances (50 µH and 250 µH) and conforms with the recommendations of VDE0876 and CISPR 16-1.
Other features of the equipment include:
• Artificial Hand
• 10-dB-attenuator in the RF path
• Switchable 150-kHz-highpass filter
• Pulse voltage limiter at the measurement output
• Remote control port
• External power supply via plugged power pack for tests on non-standardized a.c and d.c. voltages
The network may be operated manually or by remote control with TTL levels.

3 Preparation
Unpack the device
Remove the two protective hoods from the front and rear and inspect the device carefully for any dam­age.
If the device is damaged, you should notify the responsible freight carrier immediately and retain all items of packaging in order to support your complaint. The original packaging is also useful for use when shipping or transporting at a later date. You should at least keep the two protective hoods for the front and rear, to protect against damage to the control elements and connections.
Set up the device
Before starting the ENV216 for the first time, ensure that
• a PE conductor is connected,
• the ventilation openings are unobstructed,
• no signal or operating voltages above the permissible limits are present at the inputs,
• the device's outputs are not overloaded or incorrectly connected.
Failure to comply with any of these points may damage the equipment.
Caution!
Note the instruction regarding protective grounding in chapter 3, section entitled Protective grounding!
Warning!
The flow of air from above and below must be unimpeded at all times while the ENV216 is in use.
As the device is equipped with ventilation apertures on its underside, it must not be left to run unsupervised or it must be set up on a non-flammable surface (e.g. metal plate, marble slab) to avoid fire in the event of overheating.

Mains connection
Connection to the mains power supply is provided by a permanently attached mains cable. The device is not equipped with an ON / OFF switch.
Caution!
When beginning operation, the sequence below must be followed strictly:
Connect network to auxiliary protective grounding Connect mains plug to the mains power supply
Switching off:
Unplug network from the mains power supply Disconnect auxiliary grounding connection
Caution!
Due to the high level of earth leakage current, the device cannot be operated on power supplies protected by residual current devices (RCDs). The power source must be protected by a circuit breaker with a maximum rating of 16 A characteristic B or C.
If the phase connection is made correctly, LED L1 (1) must light up. If it does not:
Ø For mains plugs with symmetrical grounding connection (e.g. Schuko plugs) the plug's polarity must
be reversed.
Ø For mains plugs with asymmetrical grounding connection, phase L1 and neutral N must be swapped
by reconnecting.

Operation with non-standardized voltages
For measurement tasks on voltages that are outside the normal mains voltage ranges (e.g. <100 VAC) and for operation on d.c. (max. 50 VDC) the ENV216 control circuit is powered externally by a plug-in power supply.
Caution!
The d.c. voltage must not exceed 50 VDC!
The plug-in power supply is connected to the "EXT. POWER SUPPLY" socket (13). The input is reverse voltage protected.

Reference ground
The network is connected to the PE grounding connection for the mains power supply through the mains cable, but this is not adequate for use as a reference ground in HF noise voltage measurement.
The reference ground used can be attached flat to the grounding rail (2) on the side of the device by a broad sheet metal with three metric M4 screws (1).
2
Grounding rail on the side of housing
In order to prevent RF interference emitted by the mains grounding conductor from reaching the refer­ence mass, the grounding conductor and the reference mass are decoupled by a PE-choke. This choke should not be bridged by the EMI test receiver, which is also connected to the measurement reference ground. Therefore, either an isolated or a battery-powered receiver must be used, or a PE choke must also be placed on the PE connection of the receiver.

Connecting the equipment under test
The equipment under test is connected via the socket (1) on the front of the ENV216. Constant current must not exceed 16 A. For ambient temperatures >35°C, external air ventilation is recommended.
The RFI voltage measurement plane is located on the front panel of the ENV216. The impedance gra­dient of connections N and L1 of the socket is measured against the reference ground connectors (4­mm-jacks) to the left and right (2) of the socket (1).
Connecting the test receiver
The test receiver is connected to the N connector RF OUTPUT (1) by a 50-Ω-coaxial cable.

Measurement setup
The ENV216 Two-Line V-Network satisfies the requirements of interference measurement regulations VDE 0876, CISPR 16-1, and the U.S. FCC (Rules and Regulations Part 15J).
The measurement setups prescribed in the individual standards are largely similar. VDE regulation 0877 provides a detailed description.
Devices under test that are not equipped with permanently attached connecting wires are connected to the network using a 1 meter long, unshielded wire. For devices under test equipped with a permanently attached cable that is longer than 1 meter, the cable is laid out in a folded configuration.

Devices under test that have a separate ground connection and are not connected by integral ground­ing conductors are grounded using an additional connection cable. This is inserted into the ground con­nector (1) to the right of the test device socket and runs parallel to the mains cable.
RF- ground connectors
When measuring devices that are held in the hand during operation (e.g. electric drills), the effect of the human hand is simulated by connecting to the "Artificial Hand" hand simulation jack.
The hand simulation consists of the connection in series of a 220-pF-capacitor with a 510-Ω-resistor.
The connection is located in the front panel of the ENV216.
If the housing of the equipment under test is made entirely of metal, the "Artificial Hand" jack is con­nected to the housing the equipment under test.
If the housing is made from non-conductive material, metal foils are wound round the handles and a 60 mm wide foil is wound round the point on the housing that can also be gripped by the hand. All foils are connected together and with the "Artificial Hand" jack.
The figure in chapter 3, section entitled "Sample measurement" on the following page illustrates an example of how the foils are applied.

6 Servicing
The device does not need to be regularly serviced. Servicing is limited essentially to wiping the device's external surfaces.
However, it is recommended to check the rated specifications from time to time.
Device safety inspection
A device safety inspection of the network as defined in BGV A2 is not possible because of the required, standard-compliant configuration according to CISPR 16 and VDE 0876. Therefore, the following ex­aminations must be carried out as a minimum requirement.
Visual inspection
It should be ensured that parts relevant for active and passive safety are not visibly damaged or even unsuitable for use in the device. In particular, a check should be made to determine whether safety­critical parts may have been rendered unfit to meet the requirement to which they are subject as a re­sult of the use to which the device has been put (effects extended use, environmental influences). The following must not be damaged:
• Housing, displays, carrying handles, air vents
• Device connection cables, connection points and mains lead cleats
• Mains plug, fuse holder
• Labeling and markings, warning notices
• Isolated parts, wiring insulation
• Plug connections and clamping points
• Vent and leakage paths must not be altered unacceptably.
The firmness of the connections must be tested by tugging them briefly by hand. A check must also be made to confirm that the fuses used match the nominal ratings indicated in the documentation.
Test of the PE grounding connection
This test is intended to determine whether the resistance between contactable parts, which must be securely grounded for safety reasons, and the grounding contact of the mains connector is less than
0.3 Ω .
During the measurement, the entire length of the wire is to be moved in sections. If a change in resis­tance is noted while part of the wire is being moved, the fault must be found with a detailed trouble­shooting procedure. Defective cables must not be repaired. They must be replaced in all cases.
