Safety Precautions
To ensure proper use of the product, be sure to read this manual and the
other attached documents carefully before starting installation, operation,
maintenance and inspection.
precautions are ranked, in order of importance, as either"Warning" or
"Caution".
Incorrect handling of the device may result in death or
WARNING
serious injury.
Incorrect handling of the device may result in minor injury
CAUTION
or physical damage.
Under certain conditions, improper operation may result in serious injury
and/or damage even if it is labeled only as "Caution". Every item indicated
by either "Warning" or "Caution" should be considered significant. Be sure
to give particular care to those items.
● Do not touch the product or approach it when power connected.
Electric shock or burns may result.
● Turn off the power before starting maintenance or inspection.
Failure to do so may result in electric shock.
● Turn off the power supply of main and control circuit before
opening the cover.
●For wiring, select wire size suitable for the applied voltage and
current. Burns may result. Tighten wires with the tightening torque
specified in the instruction manual. Failure to do so may result in
fire or burns.
●Do not touch the product immediately after the power is turned off.
As it may still be hot, burns may result.
●Treat the product as industrial waste when discarding.
1. Unpacking
(1) Check that the type, coil voltage, contact arrangement and thermal
overload relay ratings and applicable capacity match the requested
specifications. The magnetic starter type is indicated on the package.
The coil voltage and thermal overload relay ratings are shown on the
inner side of the cover.
(2) Make sure that no parts have been lost or damaged.
2. Storage
Store the unit in the packing box. Do not store the packing box in a
location subject to high temperature, high humidity, corrosive gas, or
direct sunlight.
3. Mounting
(1) Mount in a dry, clean and stable location.
(2) Mounting on a vertical surface. The product must not incline more
than 15゜. (Fig.1)
(3) Use two(Fig.2) or four(Fig.3) mounting holes.
4. Connection

5. Usage
Thermal overload relay
(1) Push the reset button after unpacking. (Tripping may occur by the
impact of transportation.)
(2) Turn the adjustment dial within the scale so that the full load current of
the motor is at the ▼ mark. (Fig.4) Do not use beyond the scale, or the
expected performance cannot be obtained.

(3) By pushing the trip indicator toward the arrow, checking of control
circuit wiring can be done. (Fig.4)
(4) When tripping occurs, the trip indicator disappears. (Fig.4) (But the trip
indicator at automatic reset dose not disappears.)
(5) After tripping occurs, pressing the reset button slightly returns the
thermal overload relay to reset. (If the thermal overload relay is not
cooled sufficiently, it cannot be reset.)
(6) To change over from manual reset mode to automatic reset mode,
keep the reset button pushed as shown in Fig.5.
(7) In the case of single phase, please change connection as follows.
1. Change the control wiring connected with "3-95" to
"5-95".
2. Connect a main circuit as shown in the right figure.
3. Adjust the dial to 10% higher than its rated motor
current.
6. Maintenance and inspection
6.1 Inspection before operation
(1) Check that all screws are tightened.
(2) Check that there is no foreign matter in the unit, such as wire chips
or washers.
(3) Check that the operating circuit voltage is within the allowable
voltage fluctuation range of the coil voltage. The allowable voltage
fluctuation range is 85 to 110% of the coil voltage.
(4) In AC operation, check that operation power supply is sinusoidal
waveform (50Hz or 60Hz) without distortion or cave-in etc.
6.2 Periodic inspection
(1) Perform initial inspection early, and perform subsequent
inspections on a regular basis.
(2) Check that all terminals are tightened with the proper torque
periodically.
(3) The exchange for magnetic starter only in the case is not possible.
(4) Contacts and operating coil cannot be replaced at site.
6.3 Others
(1) When tripping occurs, open the cover and press the reset button
after removal of the failure cause (ex. overload).
(2) The proper torque
"FJ-B09WP~B25WP:0.8~1.2[N･m], FJ-B32WP:2~2.5[N･m]".
(3) The cover of FJ-B25WP may become difficult to be closed. If the
load side wiring is moved a little more to the left, the cover can be
closed easily.(Fig.6)
(4) The proper torque for the ground screw of FJ-B32WP is 2~2.5[N･m].
