3. IMPLEMENTATION AND INSTALLATION
3.1 Handling Precautions
The following explains the precautions for handling the module.
(1) Do not drop the module case and/or connector 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 sure there are no foreign substances such as sawdust or wiring
debris inside the module.
Such debris could cause fires, damage, or erroneous operation.
(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) Tighten the fixing screws within the following torque ranges.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to
damage to the screw or module.
* 1 The module can be easily mounted to a base unit, using the hook on the
upper part of the module.However, it is recommended to secure it with the
module fixing screws when used in an environment where constant
vibrations may occur.
(6) When mounting the module to the base unit, insert the module
fixing projection into the fixing hole in the base unit, and mount the
module with using the hole as a supporting point.
Incorrect module mounting may cause a malfunction, failure, or
drop of the module.
