Note the following items when using the option. Improper use may result in unexpected failure, electric shock, or
possible injury.
WARNING
•Wait at least five minutes after turning off the power before installing or wiring the inverter option.
Use a multimeter or similar instrument to check the voltage before performing installation or wiring.
(Check whether the charge lamp goes off.), as electric shock may occur
•Discharge statistic electricity from your body before handling the inverter option. Never touch the
Inverter option with wet hands, as accident or electric shock may occur
•No foreign matter such as screws, metal patches, lint, chips, and dust in the inverter option.
There is risk of fire or accident.
•Do not damage or stress the wiring, as accident or electric shock may occur.
•Wait at least five minutes after turning off the power before inspecting the inverter option. (Check
whether the charge lamp goes off.) There is a risk of electric shock.
•Never modify the inverter option, as electric shock or injury may occur.
CAUTION
•Do not install or operate a damaged option or one that is lacking parts, as injury may occur.

Altitude Up to 1000m -
①Please set up so that power terminal may become the lower side.Please set up vertically on a strong building with the
bolt.Please do not turn upside down and do not set up in a horizontal plane.
②This option generates heat, and install space more than each of 100 ㎜the top and bottom and the right and left to
secure the passage of the cooling style, please.The generated heat is radiated up. Please do not install under a weak
equipment to heat.Moreover, installation respect must use the one of the material that the temperature rise can be
endured enough.
③Please consider enough to ventilation so that the ambient temperature of the inverter and the braking resistor should
not exceed the specification value when storing in the control board etc.Please do not store in a small sealing up box
where heat radiation is bad.
WARNING
•The surface temperature of resistance becomes 400℃or less by the use state.
There is risk of fire or burn.
•Please install in a nonflammable thing such as the metals.
There is risk of fire.
•Please do not arrange the combustible in surroundings.
There is risk of fire.

CAUTION
•Check the wiring again before operating the inverter. Improper wiring may cause unexpected inverter operation or
device operation. There is a risk of accident or injury.
•Since noise is generated by the inverter, motor, and wiring, carefully monitor surrounding sensors
and devices for abnormal operation. There is a risk of accident.
