3. MOUNTING AND INSTALLATION
3.1 Handling Precautions
The handling precautions for the module are given below.
(1) Since the module case is made of resin, do not drop it or apply
strong impacts on it.
(2) Do not remove the PCB of each module from its case. This may
cause a failure in the module.
(3) Be careful not to let foreign matter such as wire offcuts enter the
module during wiring. In the event any foreign matter enters, remove
it immediately.
Otherwise, it may cause a fire, failure or malfunction.
(4) The module has an ingress prevention label on its top to prevent
foreign matter, such as wire offcuts, from entering the module during
wiring. Do not peel this label during wiring. Before starting system
operation, be sure to peel this label because of heat dissipation.
(5) Crimp terminals with insulated sleeves cannot be used with the
terminal block. Covering the wiring parts for the crimp terminals with
mark tubes or insulated tubes is recommended.
(6) Before touching the module, always touch grounded metal, etc. to
discharge static electricity from human body, etc.
Not doing so can cause the module to fail or malfunction.
(7) Tighten the module mounting screws within the following ranges.
Serrer les vis de fixation du module dans les limites suivantes.
(8) To mount the module on a base unit, fully insert the module
mounting tab into the mounting hole in the base unit and press the
module into position.
Be sure to tighten the module mounting screws within the specified
tightening torque range.
