Electrical connection
Don't use cables above rating.
The rating of the supplied power cable is 125 V 7 A. If the power exceeds the
rating, use another power cable. Use above the rating will damage the vacuum
gauge.
Check line voltage.
Prior to turning ON the power, make sure that the vacuum gauge operating
voltage and the supply voltage are in agreement. Connection of incorrect
power can cause damage to the vacuum gauge and fire.
Check connection.
For safety reasons, ground the GND terminal of the controller.
Operating conditions
Operate the vacuum gauge under the environment set forth in the
specifications.
Make electrical connection after installing components.
Fix the cable by taking care not to exert undue force to the connection between the sensor head and
sensor head cable and the connection between the controller and sensor head cable.
Lay the sensor head cable away from power lines, if possible. Noise may occur.
Moving the sensor head cable will generate frictional electricity between conductor and insulator,
which can cause an error at a low pressure.
Avoid installation of the vacuum gauge in a high temperature or high humidity place.
Securely fasten the connector fixing screw.
Plug the power cable to a 100 VAC outlet.
