Thank you for purchasing ORIENTAL MOTOR products.
Please read this operating manual thoroughly before
installing and operating the fan, and always keep the
manual where it is readily accessible.
1. Precautions
1.1 Precautions for Installation
●Do not use in a place where there is flammable gas and/or corrosive gas.
●Fans for use only in equipment of protection class Ⅰ.
Lüfter zur Verwendung in Geräten der Schutzklasse Ⅰ.
●Connect the ground wire to the ground terminal inside the terminal box.
Das Erdungskabel wird an dem als Erde gekennzeichneten Pol im Anschluβkasten angeklemmt.
●When installing the fan into your equipment, ensure that the motor lead wires are fixed and do not move.
In addition, do not apply any pressure to these lead wires.
●Installation must be performed by a qualified installer.
1.2 Precautions for Operation
●Always turn off power to thermally protected fan before conducting checks or performing work on the fan.
These types of fans will restart automatically when fan temperature falls below a certain level.
●The enclosure temperature of this fan can exceed 70℃ (depending on operation conditions).
In case fan is accessible during operation, please attach the following warning label so that it is clearly visible. Warning label
●Do not touch the fan blades when the fan is in operation.
The use of the optional fingerguard is recommended to ensure protection.
Wegen der Verletzungsgefahr dürfen die Lüfterflügel bei Ventilatorbetrieb nicht berührt werden.
Der Gebrauch des als Sonderzubehör erhältlichen Fingerschutzes ist empfehlenswert, um erhöhte Sicherheit zu gewährleisten.
