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 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 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 or sales office and request the necessary information.

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 need to warm-up the product for 3
minutes before use.
a) the auxiliary power requires isolation voltage≥2000VAC, DC
current output ripple＜10mV.
b) When sensor measuring voltage exceed 1000V, it needs
dividing input voltage by using resistor which is provided by
Weibo electronic. Different sensor uses special resistor.

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: DC +9V～+36V, ripple≤5mV
Ambient temperature: 25℃±5℃
Relative humidity: RH(45～75)％
Accuracy for Signal Power Source instrument: 0.05
(3) warming up the sensor 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 sensor Vr. (for
e.g. if input value is 100V, the output is 0-5V, the expected
output value Vz should be calculated as:
Vz=（5V-0V）× Vr/100V
(5) using output monitoring meter V2 to measuring the output
voltage V0 of the sensor, the basic introduced errorγof the
sensor should be calculated as:
γ= (Vo－Vz)/（5V-0V）×100
(6) Repeating (4) (5), if calculated absolute value is less than
the given accuracy value of the sensor, it shows the
sensor’s accurate grade is qualified.
