4 INSTALLATION AND WIRING
POINTS
(1) When installing the module, always insert the module fixing projection into the
module fixing hole of the base unit.
At that time, securely insert the module fixing projection so that it does not
come off from the module fixing hole.
If the module is forcibly installed without the latch being inserted, the module
connector and module will be damaged.
(2) When using the modules in a place where there is large vibration or impact,
screw the module to the base unit.
Module fixing screw : M3 12 (user-prepared)
(3) Do not install/remove the module onto/from base unit or terminal block more
than 50 times, after the first use of the product. Failure to do so may cause the
module to malfunction due to poor contact of connector.
CAUTION
When the modules are installed to the base unit while pressing the installation lever located at the
bottom of module, insert the module fixing projection into the fixing hole in the base unit until it
stops. Then, securely install the module with the fixing hole as a supporting point. Incorrect
installation of the module can cause an operation failure, damage or drop.
When using the Motion controller in the environment of much vibration, tighten the module with a
screw.
Tighten the screw in the specified torque range. Under tightening may cause a drop, short circuit
or operation failure. Over tightening may cause a drop, short circuit or operation failure due to
damage to the screw or module.
