Safety 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 would be associated with the equipment should 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 personal 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 operating 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 problem, do not take any action
without proper authorization. Contact the appropriate WB technical sales office and request the
necessary information.

Product Description and Application
WBV415S01 converts AC input voltage into a load independent output signal RMS 0~5V. It has
adopted electromagnetic isolation principle and RSM measurement method for real time
measurement of AC voltage (in any wave form) from electric net or electric circuit.
The product has certain advantages of total galvanic isolation between input and output, high
accuracy, low drifting by temperature, and wide temperature bearable range, etc.

Instruction of Installation and Use
1. The product has 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: Pull out the spring clasp;
Step 3: Place whole mounting trough to the DIN mounting rail properly;
Step 4: Release spring clasp to make sure the installation.
2. The product has calibrated before out of factory. After correctly wiring, it can be
powered and used immediately. But for further precise signal sampling, user needs to
warm-up the product for 3 minutes before use.The auxiliary power requires isolation
voltage≥2000VAC, DC current output ripple＜10mV, and multiple converters can share
with one set auxiliary power together.
3. Basic testing method for accuracy
(1) According to the terminal definition table to connect the testing circuit;
(2) The testing must to be done by under the following conditions；
Auxiliary power: 24V±1％，ripple≤5mV
Ambient temperature: 25℃±2℃
Relative humidity: RH(45～75)％
Accuracy for Signal Power Source instrument: 0.05

(3) Warming up the transducer for 3 minutes
(4) Using output monitoring meter V1 to measuring the output of signal power
source instrument, set any input value which is within the measuring range of
the transducer Ur. (e.g. if input value is 100V, the output is 0~5V, the expected
output value Uz should be calculated as:
Uz = 5V×Ur/100V

(5) Using output monitoring meter V2 to measuring the output voltage U0 of the
transducer, the basic introduced errorγof the transducer should be calculated
as:
γ= (Uo－Uz)/5V×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.
Caution:
1. Pay attention to the auxiliary power information, especially the auxiliary power grade,
and polarity, other wise will damage the product.
