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.

14. Mounting : DIN Rail 35mm Mounting or screw mounting

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.

3. The auxiliary power requires isolation voltage≥2000VAC, DC current

output ripple＜10mV.

4. Multiple transducers can share with one set auxiliary power together., and

the wire shared between the transducers and power should be short. It's

better to connect each transducer to the auxiliary power individually.

5. Wiring in terms of the terminal identification drawing strictly.

6. 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±5％，ripple≤5mV

Ambient temperature: 25℃±5℃

Relative humidity: RH(45～75)％

Accuracy for Signal Power Source instrument: 0.05

Sign

Sour

Transducer

Power

1 3

(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 Ir (e.g. if input value is 50A, the

output is 0-5V, the expected output value Uz should be calculated

as:

Uz＝5V×Ir/50A

(5) Using output monitoring meter V2 to measuring the output voltage

Uo of the transducer, the basic introduced errorγof the transducer

should be calculated as:

γ＝(Uo－Uz)/5V×100

(6) Repeating step (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.

2. pay attention to the wire connection; wrong terminal connection will cause

malfunction 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 prevent ABS crust, its temperature withstand is only

limited as +85 , higher than this limitation will cause the product℃

deformation. Please use and store carefully.
