Safety precautions
Installation
• Before starting wiring or inspection, switch power off, wait for
more than 1 minutes, and check for residual voltage between
terminal P/B and N with a meter etc, to avoid a hazard of
electrical shock..
• Do not remove the operator from the main body.
It may cause an electric shock.
• When using the digital operator away from the main body, use the
separated operator(E7OPTR-S).
• Suitable for use in a circuit capable of delivering not more than
5kA rms symmetrical amperes.
DANGER:
Wrong handling may cause a dangerous
situation, which can lead to death or a
severe injury.

Safety precautions
• Do not carry the inverter by holding the plastic parts, but hold the
heatsink.
The heat sink may fall and cause injury.
• Use nonflammable materials such as metal for the part where the
inverter is installed.
• When installing several inverters in a single enclosed space, install
a cooling fan to keep the ambient temperature below 45℃
• Cover the inverter during installation to protect it from metal
chip coming from drilling.
Wiring
• Always turn OFF the input power supply before wiring.
Otherwise, an electric shock or fire may occur.
• Wiring must be performed by qualified personnel.
• Always check if the bolts on the main circuit and control circuit
terminals are properly tightened.
• Turn ON the inverter only after completely assembling the covers.
Do not detach the cover when the power is ON.
Otherwise, an electric shock or fire may occur.
• Ground the ground terminal (200V & 400V class: ground to 100Ω
or less).
Otherwise, an electric shock or fire may occur.
