Plug the connection cable into the connector of the external I/O module
and tighten the connector fixing screws within the specified torque range.
Undertightening can cause mis-input due to a contact fault.
Overtightening can cause mis-input due to damaged screws or external
I/O module or a contact fault.

When installing the Numeric Keypad Panel to a control box, mount or the
like, tighten the fixing screws within the specified torque range.
Undertightening can cause a drop.
Overtightening can cause a drop due to damaged screws or Numeric
