Mounting the DC Cooling Fan

These instructions are for mounting the 120mm, 12V DC, Cooling Fan in your enclosure

As nearly everything in your enclosure produces heat, particularly the TB6560 Driver board and 24V Power Supply, it is important a Cooling
Fan be installed. It can be mounted anywhere in your enclosure but should be positioned so it services both the TB6560 Driver board and
Power Supply. The cooling fan is 12V DC and has a 230mm (approx) lead and requires connection to the DC Converter previously mounted.



AC Mains Power can kill or seriously injure

DO NOT plug in your equipment while you are working on it

Do not drop



Parts Required


Supplied Parts

1 x Cooling Fan


Parts to be sourced

4 x M4 bolt with sufficient length to pass through 5mm mounting points and your enclosure material.

4 x M4 Nut, washer and spring washer



Recommended tools

Electric drill

4mm Drill bit (appropriate for the material your enclosure is made of)

Spanner/screwdriver as per your sourced bolt head

110mm hole saw or some other tool capable of cutting out 113mm circle appropriate for the material your enclosure is made of



Parts Overview

12V DC Cooling Fan

  1. Motor Mount
  2. Fan assembly (center hub)
  3. Fan housing
  4. 4.5 mm Mounting points
  5. DC wiring

Air travels from Rear to front. To bring air into the enclosure, mount the rear on the internal surface of the enclosure. To extract air
from the enclosure mount the front on the internal surface of the enclosure.

Please check your Cooling Fan against these templates prior to drilling. Fans can vary from manufacturer to manufacturer as
much as 1-2 mm for mounting points.

Mounting Process

When choosing your mounting point positions please consider the following:

  1. The Cooling fan will require power power from the DC to DC Converter
  2. The lead on the Cooling fan is approx 230mm and will need to be mounted in range DC Converter.
  3. Orientation of fan will determine weather it extracts or brings in air
  4. Fan is not to be mounted to other parts or come in contact with other components
  5. Fan has moving parts which will need freedom to move
  6. Do not run wires directly over or on Fan as it can produce/receive interference.


Once you have selected the desired position to mount the Fan please drill 4 x 4mm holes  and 1 x 113mm (approx)
openingas per the mounting template. Fan orientation is at your discretion.


Align the bottom mounting points up with the lower 4mm holes.


Insert the 4 bolts through mounting surface and Cooling fan mounting points.


Attach the flat washers, spring washers and nuts then tighten.


Once the bolts are tightened grasp the fan and make sure it is firmly in place.

The Cooling fan is now ready for wiring.
