Handling precautions
This section describes precautions for handling the CC-Link IE controller network module
itself.
(1) Since the module case is made of resin, do not drop the module or apply
a strong impact to it.
(2) Do not remove the printed-circuit board of the module from the case.
Doing so will cause failure.
(3) Be careful to prevent foreign matter such as dust or wire chips from
entering the module. Failure to do so may cause a fire, failure or
malfunction.
(4) A protective film is attached to the module top to prevent foreign matter
such as wire chips from entering the module during wiring. Do not
remove the film during wiring.
Be sure to remove it for heat dissipation before system operation.
(5) Before handling the module, touch a grounded metal object to discharge
the static electricity from the human body.
Not doing so may cause a failure or malfunction of the module.
(6) Tighten the screws such as module fixing screws within the following
ranges.
* 1 The module can be easily fixed onto the base unit using the hook at the top of the module.
However, it is recommended to secure the module with the module fixing screw if the module is
subject to significant vibration.
