avoid changes in operation.
• Tighten the screws such as module fixing screws within the following ranges.
* 1 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.
