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 instrument.
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 possibil-
ity that the control valve will move in response.
When using an explosion-proof model, be sure to use the product correctly, paying suffi-
cient attention to the cautions in this chapter.
