5.0 MECHANICAL INSPECTION
5.1 Rotation Direction
Counterclockwise when look into impeller side.
5.2 Protection
All fans have integrated protection against locked rotor condition so that there will be no
damage to winding or any electronic component.
Restarting is automatic as soon as any constraint to rotation has been released.
As fan placed at dead angle position, and the switch was changed from off to on. Restarting
was automatic normal as soon as and proved that this fan is good fan.
5.3 Locked Rotor Protection
No damage shall be found after 72 hours continuously at condition of rotation locked.
Restarting is automatic as soon as constraint to running has been released.
5.4 Avoid the damage, check the correct voltage and proper polarity before connecting with
power.
5.5 Free Drop Shock
In minimum package condition, the fan should withstand drops on any three faces from a
height of 30cm onto a wood board of 10mm thick.
5.6 Please do not stick a grease and/or an oil to the fan housing or blade which may have a harmful
influence by a chemical reaction at high humidity.
5.7 If the fan is reinstalled, please pay special attention to the noise due to the vibration (or resonance).
5.8 During the testing of the fan, please make sure the finger guard is used for safety.
6.0 ELECTRICAL INSPECTION
6.1 Insulation Resistance
Not less than 10M ohm between housing and positive end of lead wire (red) at 500V DC.
6.2 Dielectric Strength
No damage should be found at 500 VAC for 60 seconds, measured with 1mA trip current
between housing and positive end of lead wire.
6.3 Life Expectancy
The continous duty life at given temperature after which, 90% of testing units shall still be
running.
6.4 While the fan is running, do not intentionally lock the fan for a long time since the overheating of
the motor produced by the long-time locking will damage the fan.
7.0 ENVIRONMENTAL
7.1 Improper use such as disassembling the fan, being covered with dust, or dipping the fan in
water that results in defects is not covered in the warranty. Do not use the fan in the
environment with corrosive air or liquid.
7.2 Operating Temperature / Humidity
-10℃ to +70℃ at humidity 65%+/-20% RH.
7.3 Storage Temperature
All function shall be normal after 500 hours storage at -40℃ to +70 ℃ with a 24 hour recovery
period at room temperature.
7.4 Humidity
After 96 hours, 95% RH, 40+/-2℃ per MIL-STD-202F, method 103B humidity test, the
measured data on insulation resistance and dielectric strength shall meet the specificaiton.
7.5 Do not place or store the fan in the environment with high/low temperature/humidity. Do not
store the fan for over 6 months; even if the fan is stored in room temperature for over 6
months, the fan may have the electric current leakage.

8.0 REMARKS
8.1 Material and construction are subject to change without
advance notice. The changes should be within specification.
8.2 All fans shall meet the quality inspection under sampling
plan MIL-STD-105E as follow:
Critical 0.25%
Major 1.00%
Minor 2.50%
9.0 OUTLINE STYLING & DIMENSIONS
LEAD WIRES : UL 1007, AWG26, L = 295 +/- 10 mm
Red = positive ; Black = negative.
10.0 Notes:
10.1 Please do not touch and push Fan Blade with fingers or others,
fan blade and ball bearings may be damaged and it causes noise defect.
10.2 Do not carry the fan by its lead wires.
10.3 lf the fan does not have the polarity protection function, the connection of the
colored wires should be red + red, and black + black, or else the fan will be
damaged in no time.
10.4 For the models without reverse connection of polarity protection, please do not
connect the lead wire in reverse
10.5 Please don't install this fan in series with 2x voltage inputs. For example, if a single
fan rated at 12V, then don't install two of them in series with 24V input.
10.6.Every specific fan is designed for its certain application (project). Therefore, if you want to
use this fan in other application (project), please inform ADDA first so that we can confirm
whether there is any issue which might be incurred from the reason of this different
application (project) or not.
10.7 The"Life Expectancy" of this fan has not been evaluated for use in combination with any
end application. Therefore,the Life Expectancy in the Test Reports(L10 and MTTF Report)
that relate to this fan is for reference only and shall not construe any kind of warranty of
ADDA to the life of any specific fan,either expressed or implied.
10.8 The period of product warranty,unless otherwise agreed by ADDA in written,shall be 12 months
staring from the date of production.
