Work in accordance with the electric local wiring rules and standards and the working standard specified by the power company.
In order to avoid motor burn-out due to over current, be sure to mount an overload protection device (such as the motor
breaker) that matches the ratings on each fan.
(Select a motor breaker that supports the maximum current multiplied by 1.2 to 1.5 (described in the "Specifications"
on page 8).)
Always install the earth leakage breaker.
Connect the power cord shown as dotted lines in the "Wiring Diagram".
Open the terminal cover and pass power cord through the gum grommet.
Connect the power cord according to the "Wiring Diagram", "Power cord treatment" (on rear cover page) and "Connecting
wiring" (on rear cover page).
When connecting the power cord, fix the power cord to the hanging
bolt so that the power connector is not under tension.
(The K25DSF2NET do not have terminal covers.)
As water may enter the connector along the power cord, use a trap
or other type of treatment for the power cord (see illustration at right).
After the power cord has been connected, always mount the terminal cover.
(Except K25DSF2NET.)
A thermal fuse is mounted inside the motor of this product for protection.
If the source voltage differs from ratings or if power cord is not correctly
connected, the temperature of the motor windings may increase. In this
case, the thermal fuse will blow and the motor will stop. Once the fuse
blows, the motor cannot restart itself (that is, it cannot rotate).
Locate and remove the cause of the error, and replace the motor.
Note that an unstable (or temporarily installed) power supply may cause the thermal fuse to blow and the motor may stop
during a trial run.
After wiring, check the rotation direction in case of three phase motors.
Electric wiring cautions
Installation Instructions
In order to avoid the danger, it must be connected by qualified technician.
Incorrect wiring may result in current leakage or fire.
CAUTION
CAUTION
3.Power cord connection
This product must be properly and reliably grounded.
There is a possibility of receiving an electric shock.
CAUTION
Exercise care when you connect cords.
When operating the motor while using the different source voltage from ratings, if you
arrange the cabling differently from that shown in the wiring diagram, or if you mistake
single-phase for three-phase, the motor may burn out.
