This section explains the specifications of the Cooling fan unit (Q170FAN) used for the
Motion CPU module.
(1) Removable conditions of the Cooling fan unit
It is possible to remove the Cooling fan unit (Q170FAN) in order to disperse heat
from inside the Motion CPU module according to the number of Motion CPU
module and ambient temperature conditions.
Removable/Not removable of the Cooling fan unit (Q170FAN) by number of
Motion CPU module and ambient temperature is as follows.
(a) When using only one Motion CPU module
It is possible to remove the Cooling fan unit if the ambient temperature in
which the Motion CPU module will be operating is 0 to 40°C (32 to 104°F) .
(b) When using two or more Motion CPU module
Do not remove the Cooling fan unit( Q170FAN).
