Installation
Location for installation
The fan is designed and manufactured for installation in equipment.
Install it in a well-ventilated location that provides easy access for inspection.
The location must also satisfy the following conditions:
•
Inside an enclosure that is installed indoors
•
Operating ambient temperature
−
10 to +60 °C (+14 to +140 °F) (non-freezing)
•
Operating ambient humidity 85% or less (non-condensing)
•
Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas)
or liquid
•
Area not exposed to direct sun
•
Area free of excessive amount of dust, iron particles or the like
•
Area not subject to splashing water (rains, water droplets), oil (oil
droplets) or other liquids
•
Area not subject to continuous vibration or excessive shocks
•
Area free of radioactive materials, magnetic fields or vacuum
•
Area free of excessive electromagnetic noise (from welders, power
machinery, etc.)
When using near a switching circuit or high-frequency power supply, the
induced current may flow inside the fan due to electromagnetic noise
(conductive noise, radiative noise). If the induced current flows, the
electric corrosion is caused in the bearings of the fan. As a result, it may
generate the noise or shorten the service life of the products. Use the fan in
the environment that the electromagnetic noise does not cause.
How to install the fan
Install the fan onto an appropriate flat metal plate having excellent vibration
resistance and heat conductivity. Drill holes on the mounting plate and fix the
fun on the plate using screws (not supplied).
Screw size: M4
Tightening torque: 0.6 N·m (5.3 lb-in)
For air orientation and rotational direction, see the indications shown on the
fan’s side frame.
Connecting the power supply
Connect the red wire to the positive
(+) power supply and the black wire
to the ground connection.
Check the voltage specification on
the product identification plate and
input the correct voltage.

Ground the motor using the motors with a Protective Earth Terminal
.
Applicable crimp terminal:
Insulated round crimp terminal

Connection of the alarm/sensor
Stall alarm, electronic alarm type
The orange or yellow wire is
lead wire for the alarm circuit.
GND is common to the sensor
and power supply.
If the fan stalls while the
power is on, an alarm signal
(H level) is output.

Note
The stall alarm type of fan is not equipped with a delayed
trip-point alarm circuit. Therefore, an external delay function
is necessary to avoid the detection of fan start. The set time
of the delay function should be at least one second.
Pulse sensor type
The yellow wire is lead wire
for the pulse output. GND is
common to the sensor and
power supply.
Two cycles of rectangular
waves are output per rotation.

Overheat protection
The fan is equipped with an internal protective circuit against overheating. In
the event a lock-up condition is detected, this function automatically controls
the current flow to the fan motor’s windings, thus preventing the fan blades
from locking and burning out. The fan resumes operation automatically as
soon as it is released from the locked condition. Be sure to shut off the power
to the fan before performing an inspection.
