Safety precautions
The precautions described below are intended to prevent danger or
injury to the user and other personnel through safe, correct use of
the product. Use the product only after carefully reading and fully
understanding these instructions.
Warning
Handling the product without observing the
instructions that accompany a “Warning” symbol may
result in serious injury or death.
Caution
Handling the product without observing the
instructions that accompany a “Caution” symbol may
result in injury or property damage.
Warning
•Do not use the product in explosive or corrosive environments, in
the presence of ammable gases, locations subjected to splashing
water, or near combustibles. Doing so may result in re, electric
shock or injury.
•Only qualied and educated personnel should be allowed to
perform installation, connection, operation and nspection/
troubleshooting of the product. Handling by unqualied and
uneducated personnel may result in re, electric shock or injury.
•Do not transport, install the product, perform connections or
inspections when the power is on. Always turn the power off before
carrying out these operations. Failure to do so may result in electric
shock.
•Turn off the power in the event the overheat protection device
(thermal protector) is triggered. Failure to do so may result in injury
or damage to equipment, since the fan will start abruptly when the
overheat protection device (thermal protector) is automatically
reset.
•The fan for class I equipment. Be sure to ground the protective
earth conductor when installing the fan. Failure to do so may result
in electric shock.
•Install the fan in an enclosure in order to prevent electric shock or
injury.
•Keep the input-power voltage within the specied range to avoid
re and electric shock.
•Connect the cables securely according to the wiring diagram in
order to prevent re and electric shock.
•Do not forcibly bend, pull or pinch the cable. Doing so may result
in re.
•Turn off the power in the event of a power failure, or the fan will
suddenly start when the power is restored and may cause injury or
damage to equipment.
•Do not disassemble or modify the fan. This may cause electric
shock or injury. Refer all such internal inspections and repairs to
the branch or sales ofce from which you purchased the product.
Caution
•Do not use the fan beyond its specications, or electric shock,
injury or damage to equipment may result.
•Keep your ngers and objects out of the openings in the fan. This
may cause injury.
•Do not touch the motor during operation or immediately after
stopping. The surface is hot and may cause a burn.
•Do not hold the lead wire. This may cause injury.
•Keep the area around the fan free of combustible materials in order
to prevent re or a burn.
•To prevent the risk of damage to equipment, leave nothing around
the fan that would obstruct ventilation.
•Do not touch the rotating parts (runner) when the fan is in
operation. This may cause injury.
•When an abnormality is noted, stop the operation immediately, or
re, electric shock or injury may occur.
•The motor’s surface temperature may exceed 70 °C
(158 °F), even under normal operating conditions. If
a fan is accessible during operation, post the warning
label shown in the gure in a conspicuous position to
prevent the risk of burns.
Warning

•Dispose the product correctly in accordance with laws and
regulations, or instructions of local governments.

included. Report any missing or damaged items to the branch or
sales ofce from which you purchased the product.
•Fan .............................................................................. 1 pc.
•Power cable ................................................................ 1 pc.
•Air Control Louver ..................................................... 1 pc.
•Set of mounting screws for fan mounting .................. 1 set
(M5 Hexagonal socket head screws with captive washer,
Hexagonal nuts with ange 4 pcs. each)
•Mounting screws for Air Control Louver (M5 Cross-recessed pan
head screws with captive washer) .............................. 4 pcs.
•Operating manual (this manual) ................................. 1 copy
Checking the model name
To verify that the unit you’ve purchased is the correct one, check the
model number shown on the identication plate.
MBS18-BH, MBS18-BWH, MBS18-DH, MBS18-DWH,
MBS18-TH, MBS18-TWH, MBS20-BH, MBS20-BWH,
MBS20-DH, MBS20-DWH, MBS20-TH, MBS20-TWH
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 elds 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 ow inside the fan due to
electromagnetic noise (conductive noise, radiative noise). If the
induced current ows, 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 at metal plate having excellent
vibration resistance and heat conductivity. Consider the weight of the
fan and install the fan in a location where sufcient strength can be
ensured.
Drill mounting holes in your equipment and afx the fan using the
supplied screws and the four mounting holes provided in the fan
casing.

Overheat protection
The fan uses a thermal protector for overheat protection. Once the
temperature reaches a specied level, the internal thermal protector
that has an automatic-return feature is triggered to stop the fan
operation.
Be sure to turn off the power when checking the thermal protector.
Operating temperature of thermal protectors
Open (Power OFF) .........130±5 °C (266±9 °F)
Close (Power ON) ..........82±15 °C (179.6±27 °F)
