Important Precautions When Using Wga-680A; Precautions On Ce Marking - KYOWA WGA-680A Series Instruction Manual

IMPORTANT PRECAUTIONS WHEN USING WGA-680A

NOTE
The output signal (voltage/current) when the transducer cable is broken.
When the transducer cable is broken, the WGA-680A may output the following output signal
(voltage/current). Therefore, take countermeasures to avoid the adverse effect, from the output signals,
on the other measuring instruments.
Output signal (voltage): Approx. -13 V
Output signal (current): Approx. 0 mA
The output signal (voltage/current) and unbalance load

PRECAUTIONS ON CE MARKING

NOTE
Be sure to mount the product on the control panel, etc. Before turning ON the power, make sure the
product is covered to avoid contact with hands.
The product connection should be executed by experts in electrical work.
To immediately turn OFF the product, place switches or circuit breakers inside the building and near the
product and display the functions as well.
Use switches and circuit breakers conforming to the IEC60947-1 and IEC60947-3.
Use the product in area where elevation is 2000 m or below.
When mounting the product in your system, approaches to satisfy the CE marking requirements vary
with the configuration of the control panel to be used, the other devices to be connected, and wirings.
Therefore, customers are required to check whether the CE marking requirements on the product are
satisfied or not.
Use shielded cables as input cables, output cables and control cables.
Wiring should be 30 m or less.
Before connecting the control cables, be sure to mount ferrite core near the terminal.
Recommended ferrite core
Be sure to connect the GND terminal to the ground by using the optional ground wire.
