4 SETUP AND PROCEDURES BEFORE OPERATION
4.1 Handling Precautions
(1) Do not drop the module case or subject it to heavy impact.
(2) Do not remove the PCB of the module from its case. Doing so may cause the module
failure.
(3) Be careful not to let foreign materials such as swarf or wire chips enter the module.
They may cause a fire, mechanical failure or malfunction.
(4) The top surface of the module is covered with a protective film to prevent foreign
materials such as wire chips from entering the module during wiring.
Do not remove this film until the wiring is completed. Before operating the system, be
sure to remove the film to provide adequate heat radiation.
(5) Before handling the module, touch a grounded metal object to discharge the static
electricity from the human body.
Failure to do so may cause the module to fail or malfunction.
(6) Tighten the screws such as module fixing screws within the following ranges.
Loose screws may cause short circuits, failures or malfunctions.
*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 sig-
nificant vibration.
(7) To mount the module, while pressing the module mounting lever located in the lower
part of the module, fully insert the module fixing projection(s) into the hole(s) in the
base unit until it stops. Improper mounting may result in malfunction, breakdown or
the module coming loose and dropping.
