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. In the text, the content that distinguishes IE3 motor and IPM motor is described in IE3 motor (left side) and IPM motor (right side) either separately

or together. Please read this against the corresponding motor.

For IPM moto r, re ad thi s blow er instru c tion manu al and the ins truc tio n man ual for the ded ica ted inv e rte r uni t (Tosh ib a

inv erte r) re quir ed whe n d rivin g the mot or, and us e i t pr ope rl y.

Please read this manual for the perfect capability to be assured and also for its maintenance and inspection.

Please be sure to deliver this instruction manual not only to the contractor but also to the end user.

1．Inspection confirmation at the time of purchase (IE3 motor)

Please check with the nameplate of the blower and the specification table

below to see if it is the product you ordered.

Especially depending on the area, there is a distinction of 50 · 60 Hz so

please check. Also please check for damage etc. during transportation.

1．Inspection confirmation at the time of purchase (IPM motor)

Please check with the nameplate of the blower and the specification table

below to see if it is the product you ordered.

For inverter drive there is no distinction of 50 · 60Hz depending on the

region. Also please check for damage etc. during transportation.

2．Outline(IE3 motor, IPM motor)

This is a “low noise type blower” realized by improving the air pressure characteristics and suppressing noise of our long-reputed WTB Series.

Owing to the roll filter employed, the filter can be replaced easily with no need of cleaning the filter.

3．Precautions when using (IE3 motor)

・Because IE3 suppresses generation loss, rotation speed generally becomes

faster than IE 1 (up to now motor). When IE1 (standard motor) is replaced

with IE3 (high efficiency motor), the output of the motor increases as this

rotational speed increases. Motor efficiency is high, but as the output

increases, power consumption may increase.

・Also, since the (primary and secondary) resistors are lowered to reduce

copper losses, the starting current is higher for IE1 (up to now motor), and

it is necessary to change wiring breaker, electromagnetic switch, thermal

relay, etc. It may become.

3．Precautions when using (IPM motor)

・IPM motors can not be operated by directly connecting a commercial power

supply (50/60 Hz).Drive with the inverter for IPM motor operation. In

particularly important equipment, it is recommended to prepare an

inverter spare in case of failure.

・Since an IPM motor needs to be controlled based on the position of the rotor,

it is not possible to operate multiple IPM motors with one inverter.

・If you combine an IPM motor with an inverter from different manufacturers,

the inverter or motor may malfunction, or reverse operation depending on

the machine may cause unexpected behavior.

・When the rotor of the IPM motor is mechanically rotated externally, the

magnetic field of the permanent magnet generates an induced voltage

between the motor terminals. Therefore, the inverter may be damaged

depending on the risk of electric shock and the rotational speed at the time

of power off.

・If the cable between the IPM motor and the inverter is long, it may not be

able to operate normally due to the increase of inverter surge and the

attenuation of sensor signal.

・The IPM motor has a permanent magnet inside, which requires careful

handling. Please contact the manufacturer you purchased for maintenance.

DANGER

PROHIBITION

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. Be sure to use the burner in a manner that the rated current value and rated flow

rate are not exceeded.

ELECTRIC

SHOCK

Electric shock attention

When you remove the cover of a terminal box, please be sure to carry out after shutting off a former power supply.

PROHIBITION

Do not disassemble

Because you might be hurt with a turning impeller please never remove Looking cover while driving.

COMPULSON

Please fix a blower with an anchor bolt on the stable foundation.

COMPULSON

To fix the piping from the blower be sure to provide independent supports.

PROHIBITION

Do not use the attached gasket for sealing this blower.

Put the replaced old gaskets pouch and throw away them according to the waste disposal regulation or 「the waste cleaning regulation」.

Never burn up them.

7．Transportation method (IE3 motor, IPM motor)

As for lifting, please use the eyebolt (3 places)which is assembled to the main body as shownon the right.

Never use the handle of the silent cover.

8．Installation (IE3 motor, IPM motor)

・Secure a space at least 1m around the blower in consideration of disassembly cleaning and repair.

・Please avoid the place described below.

･Places sucking the corrosive gases.

･Place with much dust.

･Place that gets wet with rainwater.

･Place where the circumference will be 40 ℃ or more.

・Fix to the stable foundation firmly with an anchor bolt.

When you install on a steel-materials structure unavoidably, please use the rubber mount of an option.

・In order to prevent offset load, please install so that a blower axis becomes horizontal.

9．Piping(IE3 motor, IPM motor)

・For the piping, be sure to provide independent supports for fixing, and use the accompanying rubber joints to protect the blower from the direct impact of

load and vibration from the piping.

・Piping size should be the same diameter as the blower, or larger size.

・ A straight part of a blower exit pipe more than three times longer than pipe diameter is required.

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.

2). Current detection method of thermal relay

As shown in the figure below, the thermal relay at the star delta start has the line current detection method and the phase current detection method, and

the selection of the heater rating is different. In the line current detection method, the heater rating is selected based on the motor full load current. On the

other hand, in the phase current detection method, the heater rating is selected based on the current of 1 / √3 of the full load current of the motor. In this

method, the frame size of the thermal relay can be made smaller than that of the line current detection method, but since the wiring size of the motor circuit

does not change in any detection method, in the case of the phase current detection method, Since it is necessary to consider whether wire connection is

possible or not, the line current detection method is recommended.
