3. Handling
CAUTION
z Use the programmable controller in an environment that meets the general
specifications contained in CPU module User's Manual to use.
Using this programmable controller in an environment outside the range of
the general specifications may cause electric shock, fire, malfunction, 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 mounting 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.
Not doing so may cause damage to the module.
z Do not directly touch the conductive area or electronic components of the
module.
Doing so may cause malfunction or failure in the module.
3.1 Handling Precautions
(1) Since the module case is made of plastic, do not drop it or subject it to
strong impact.
(2) The module can easily be secured to the base unit using the hooks
located at the top of the module. However, if the module is to be placed in
an area that is subject to strong vibration or impact, we recommend that it
is secured with module fixing screws (to be provided by the user). In this
case, tighten the module fixing screws within the following torque range.
Module fixing screws (M3
× 12): Tightening torque range is from 0.36 to
0.48 N
