■Installation Conditions
■Mounting Fans to Machinery
Install the fan in a location that meets the following conditions. Use
in a location that does not satisfy these conditions could damage the
product.
● Indoors (This product is designed and manufactured to be
installed within another device.)
● The ambient temperature and humidity for operation and storage
differ according to the product. Refer to the pages where each
product is listed.
● Not exposed to explosive, flammable or corrosive gases
● Not exposed to direct sunlight
● Not exposed to water
● No oil or grease, organic solvents, acid or alkaline chemicals
● Not exposed to continuous vibration or excessive impact
●Axial Flow Fans
To mount the fan to machinery, drill the mounting holes, referring
to the panel cut-out in each page where product is listed (for some
fans, the shape of the mounting holes is different for the intake side
and the outlet side).
To prevent vibration, mount the fan securely to a strong metal plate.
Installation screws are not included with the fan. Use screws of
suitable size, referring to the dimensions and the panel cut-out.
(Installation screws are supplied with the fan kit.)
■Mounting Direction of Fans
Fans can be mounted such that air is blown either horizontally or
vertically. In addition, they can be mounted against either the outlet
side or the intake side.

The MU925 type cannot be affixed with a single flange.
Mount using screws that pass through both flanges.
When mounting the MU1238 type using a single flange, use a plain
washer with an outer diameter of ϕ8 mm (ϕ0.31 in.) or less.

■Installing Accessories
Dust or objects entering the machinery through the fan opening
can affect the life of the machinery and cause accidents. To
ensure safety and maintain performance, it is recommended that
accessories such as finger guards, filters and screens be installed on
fans.
For installing of accessories below, refer to the following page.

●EMU and MU Series, and Enclosure Fan Module (MU
Series Fan Type)
Power supply terminals are located in the fan frame. Using the
accessory plug cord (the enclosure fan module comes with a plug
cord) makes connection easy.

Connections

Use the black and red lead wires extending from the fan, connecting
the red wire to the plus (+) terminal and the black wire to the minus
(−) terminal. (Common to all DC axial flow fans.)
Even if connection is reversed by mistake, the fan is equipped with a
protection circuit to keep current from flowing in the wrong direction.
For the MDS, MD, MDA, MDV, MDE and MDP products to confirm
with safety standards, use a DC power supply with reinforced
insulation on the primary side.

●Connection to MRS Series Terminal Box Fan
The MRS Series (except for MRS20 and MRS25) fans use a
terminal block for the power supply connection, allowing the lead
wires to be fixed securely. It is recommended to use a crimp terminal
to connect the cord to the terminal block.

■Speed Adjustment
The DC fan can be operated within the operating voltage range.
When the input voltage is varied within this operating voltage range,
the fan speed varies proportionally to the voltage and the fan air flow
characteristics also vary.
