This chapter describes the notes on the explosion-proof 700 Series.
Precautions for safe work
Warning
Do not perform wiring with wet hands or while the device is energized. This may lead to
electric shock. Turn the power off before starting the work and work with dry hands or use
gloves.
Follow the work procedure defined in the explosion protection guidelines when performing the
power distribution work in an explosion-proof area.
For devices equipped with the pressure-resistant, explosion-proof specifications, do not open
the cover during operation (while the power is on).
Cautions
Do not get on the installed device or use it as a step stool. This is dangerous because the
device may tip over.
Do not touch the device during operation without reason. This is dangerous because the
surface may be hot or cold depending on the usage environment.
Be careful not to touch the edge of the cover or the screw threads of the main unit when
opening the cover of the terminal box. You may be injured by these parts.
Use a DC power supply with overload protection. Overload may cause smoke or fire.
If a tool or other item touches the glass part of the display, it may break, leading to an injury.
Be careful. Wear safety glasses during work.
This product is heavy. Be careful where you step and wear safety shoes during work.
Do not touch the feedback lever or other moving part while the device is operating. You may
be injured by getting your hand or other body part caught in them.
Properly use the power supply based on the specifications. Inputting a different power supply
may damage the device.
Use gloves and other protective equipment during work in a hot, cold, or other severe
environment.
Do not move the device close to a magnet or magnetic driver. The control valve may operate.
Apply the correct supply air pressure in acoordance with the specification of the device. The
overpressure may cause abnormal actions of the control valve or damage to the pressure
gauge.
When using the explosion-proof 700 Series, sufficiently understand the notes in this
section and use it correctly.
