4. Loading and Installation
The following is explanations of the handling precautions and
installation environment, which is common to modules when handling
AJ61BT11 and A1SJ61BT11 from unpacking to installation.
For the details of loading and installation of the module, refer to the
user's manual of the programmable controller CPU module used.
4.1 Handling precautions
The following is an explanation of handling precautions of the module.
(1) Do not drop the module case or terminal block, or subject them to
heavy impact since they are made of resin.
(2) Do not remove the print circuit board of each module from its case.
This may cause a failure in the module.
(3) Prevent foreign matter such as dust or wire chips from entering the
module.
Such foreign matter can cause a fire, failure, or malfunction.
(4) Solderless terminals with insulation sleeve cannot be used for the
terminal block. It is recommended that the wiring connecting sections
of the solderless terminals will be covered with a marking tube or an
insulation tube.
(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 module mounting screws and terminal screws within
the following torque range.
(7) Insert the tabs at the bottom of the module into the holes in the
base unit before mounting the module. (For the AnS series
modules, make sure screws are securely tightened to the base unit
with the specified torque.)
Incorrect mounting may cause malfunction, failure, or drop of the
module.
