Safety Cautions
- iii -
Operate the vacuum gauge under the environment set forth in the specifications.
If the vacuum gauge is to be shipped to other site, repack it in the same way as
on delivery. If the gauge is shipped bare, it may be damaged.
When discarding the vacuum gauge, comply with your local regulations. If
the gauge was used in an environment that can cause hazards to human body,
have it disposed of by an authorized specialist in disposal.
Customer shall be responsible for the cost relating to disinstallation.
The operating voltage of this gauge is 100 to 240 VAC. Check the line voltage
before connection. If incorrect power is applied, damage or fire can result.
Ratings of the power supply cable plug
Ratings of the power supply cable plug are 125V/10A. Please process the plug
when you use it exceeding ratings of the power cable.
Don’t long contact with chemical cleaning cloth, don’t wipe with benzene or
thinner. The pointer may become unstable due to static electricity. In the case,
apply a commercially available antistatic agent to the cover.
The contact output capacity is 100VAC/0.5A, 24VDC/1A (resistance load).
If power higher than this is opened/closed, do not use the contact of the vacuum
gauge, but use a large capacity switch in conjunction.
Aluminum electrolytic capacitor and relays is used for the electric circuit in
the sensor controller. Generally, the life expectancy of the aluminum
electrolytic capacity is limited and the higher the surrounding temperature, the
shorter the life. It is recommended to replace the aluminum electrolytic
capacitor and relays once every five years or at the time or repair or overhaul
to prevent components from being damaged.
Lifetime of sensor head cable and connector
Female connector is used in the sensor head cable and detection unit. This
female connector has a lifetime. A large current load may cause a fire in the
connector connection area. Avoid the frequent insert/remove of connector to
prevent a heavy load and loosens of the connector connection.
