Cautions to ensure safe operation
Warning
Do not perform wiring work, turn on the electricity, etc., when your hands are wet. There is a risk of
electric shock. Perform this work with the power supply turned off, and with dry or gloved hands.
When wiring in a hazardous area, work according to the methods prescribed by the guidelines for the
hazardous area.
For flameproof explosion-proof specifications, do not under any circumstances open the cover during
operation (when powered up).
Caution
After installing the device, do not place your body weight on it, use it as a scaffold, etc. There is a risk that
it could fall over.
Do not touch the device unnecessarily while it is in operation. Depending on the environment in which
the device is used, there is a danger that the surface of the device may be very hot or very cold.
When opening the cover of the terminal box, be careful of the edges of the cover, the threads of the
screws on the main unit, etc. There is a possibility of injury.
Use a DC power supply that has overload protection. An overload can cause the emission of smoke and
fire.
Bringing tools and the like into contact with the glass portion of the display can cause damage or injury.
Exercise sufficient caution. In addition, be sure to wear safety glasses.
As this product is extremely heavy, watch your footing, and be sure to wear safety shoes.
When the device is in operation, do not touch moving parts such as the feedback lever. Your hand may
become caught, resulting in injury.
Supply power correctly based on the specifications. An incorrect power input can damage the instru-
ment.
When working in a high-temperature or low-temperature environment, wear gloves and other protective
equipment.
Do not bring magnets or magnetic screwdrivers near the device. There is a possibility that the control
valve will move in response.
