  • Page 3: 1．Inspection Confirmation At The Time Of Purchase

    Thank you very much for your purchase of SSTB type silent blower. This instruction manual is for your safety when using IE3 motor (small low-voltage three- phase cage induction motor) or IPM motor (permanent magnet synchronous motor) (hereinafter referred to as IE3 motor or IPM motor) And instructions for handling.

  • Page 4: 3．Precautions When Using

    3．Precautions when using (IE3 motor) 3．Precautions when using (IPM motor) ・Because IE3 suppresses generation loss, rotation speed generally becomes ・IPM motors can not be operated by directly connecting a commercial power faster than IE 1 (up to now motor). When IE1 (standard motor) is replaced supply (50/60 Hz).Drive with the inverter for IPM motor operation.

  • Page 6: 5．Safety Precautions

    5．Safety precautions(IE3 motor, IPM motor) Be sure to thoroughly read this instruction manual and other attached documents before installation work, test operation adjustment, maintenance and inspection, familiarize all about equipment knowledge, safety information, and precautions before using. In this instruction manual, the rank of safety precautions is classified as "danger", "warning", "caution".

  • Page 7: 6．Please Be Sure To Read

    5．Safety precautions(IE3 motor, IPM motor) DANGER Do not drive beyond the capability of the equipment This machine is designed so that the current value does not exceed the rated current value during operation at the rated flow rate. If the discharge flow rate exceeds the rated flow rate due to, for example, no resistance at the outlet or downstream from the outlet, the overcurrent could cause failure or seizure of the motor.

    11．Star delta starting(IE3 motor) 1). Notes on star delta start There are three electromagnetic contactor type and two magnetic contactor type in the star delta starting method. 2 Electromagnetic contactor type circuit is simple and economical, but since voltage is constantly applied to the windings of the motor even when the motor is stopped, safety during maintenance and inspection, dust and humidity are high Because it is necessary to pay attention to insulation degradation between the windings of each motor phase winding and winding to ground at the place, 3 electromagnetic contact type is recommended.
