claim
The information in the safety claim of the equipment documentation is intended to ensure that
equipment is properly installed in order to maintain it in a condition.
It is assumed that everyone who will be associated with the equipment will be familiar with the
contents of that safety section, or this safety guide.
When electrical equipment is in operation, dangerous voltages will be present in certain parts of
the equipment (e.g. the input terminal). Failure to obverse warning notices, incorrect use, or
improper use may endanger personnel and equipment and course p ersonal injury or physical
damage.
Before working in the terminal strip area, the equipment must be isolated.
Proper and safe operation of the equipment depends on appropriate shipping and handling, proper
storage, installation and commissioning, and on careful operation, maintenance and servicing.
The op erating manual for the equipment gives instructions for its installation, commissioning, and
operation. However, the manual cannot cover all conceivable circumstances or include detailed
information on all topics. In the event of questions or specific pro blem, do not take any action
without proper authorization. Contact the appropriate WB technical sales office and request the
necessary information.

WBV414U01 converts AC input voltage into a load independent output signal dc (0) 4-20mA. It
has adopted electromagnetic isolation principle and average measurement method for real time
measurement of AC voltage ( sine form ) from electric net or electric circuit.
T he product has certain advantages of total galvanic isolation between input/output and auxiliary

1. The product h as adopted structure compliance with EN50022; suitable for DIN rail
mounting NS35/7.5, NS35/15. Installation steps are as following (please reference to
dimensional drawing):
Step 1: Immobilize one side of product ‘ s mounting trough to the DIN mounting rail;
Step 2: P ull out the spring clasp;
Step 3: P lace whole mounting trough to the DIN mountin g rail properly;
Step 4: Release spring clasp to make sure the installation.
2.
The product has calibrated before out of factory. After correct ly wiring, it can be powered
and used immediately. But for further precis e signal sampling , user need to warm-up the
product for 3 minutes before use.
a)
the auxiliary power requires isolation voltage ≥ 2000V
AC
, DC current output ripple ＜
10mV , and multiple converters can share with one set auxiliary power together.
b)
output signal (Iz) is designed to follow the impedance load value of 250 Ω;When
Resistance (R
L
) is less than 100 Ω,the user must add output current circuit a power
reduced resistance load R 0to keep the summation of total impedance value is
between 100 Ω～250 Ω
3. basic testing method for accuracy
(1) According to the terminal definition table to connect the testing circuit;
(2) T he testing must to be done by under the following conditions ；
A uxiliary power: 24V ±1％， ripple ≤5mV
A mbient temperature: 25 ℃± 2℃
Relative humidity : RH(45 ～75) ％

(3) warming up the transducer for 3 minutes
(4) using output monitoring meter V1 to measuring the output of signal power
source instrument, set a any input value which is within the measuring range of
the transducer U r. (for e.g. if input value is 100V , the output is 4-20 mA , the
expected output value Iz should be calculated as:
Iz = (20mA － 4mA) × U r/ 100V ＋ 4mA
(5) using output monitoring meter V2 to measuring the output voltage U 0 of the
transducer, the basic introduced error γof the transducer should be calculated
as:
γ = (Uo － Iz × 250 Ω )/ [(20mA － 4mA) × 250 Ω ] × 100
(6) Repeating (4) (5), if calculated absolute value is less than the given accuracy
value of the transducer, it shows the transducer ’ s accurate grade is qualified.

of the product and even damage the product;
3. Don ’ t dismantle the product, and carry with care to avoiding bump and fall of the
product;
4. If the product has been using under the environment with strong magnetic field
interference, please pay attention to the shield of input wire, and the output signal wire
should be as short as possible. For product intensive installation, the space between
each product should not be smaller than 10mm.
5. Only use identified terminals.
6. There is no lightening strike prevention circuit design in this product. For out door and
hazardous environment using, please add protective alternatives.
7. This product uses fire pre vent ABS crust, its temperature withstand is only limited as
+85 ℃, higher than this limitation will cause the product deformation. Please use and
