3. Handling
CAUTION
z
Use the programmable controller in the operating environment that meets
the general specifications given in the user’s manual of the CPU module.
Using this programmable controller in an environment outside the range of
the general specifications could result in electric shock, fire, erroneous
operation, and damage to or deterioration of the product.
z
While pressing the installation lever located at the bottom of module, insert
the module fixing tab into the fixing hole in the base unit until it stops. Then,
securely mount the module with the fixing hole as a supporting point.
Incorrect loading of the module can cause a malfunction, failure or drop.
When using the programmable controller in the environment of much
vibration, tighten the module with a screw.
Tighten the screw in the specified torque range.
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.
z
Completely turn off the externally supplied power used in the system before
mounting or removing the module. Not doing so could result in damage to
the product.
z
Do not directly touch the module's conductive parts or electronic
components.
Touching the conductive parts could cause an operation failure or give
damage to the module.
3.1 Module Handling Precautions
(1) Since the module case is made of resin, do not drop it or subject it to strong
impact.
(2) 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 or shock.
In this case, tighten the module fixing screws within the following clamping
torque range.
Module fixing screws (M3): clamping torque ranging from 0.36 to 0.48 N
