3. Loading and Installation
3.1 Handling Precautions
(1) Do not drop or apply severe shock to the module case since it is made of
resin.
(2) Always make sure to touch the grounded metal to discharge the electricity
charged in the body, etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module.
(3) Tighten the screws such as module fixing screws within the following range.
Screw location
Tightening torque range
External power supply terminal screw (M2.5 screw) ( 1) 0.40
N•m
Module fixing screw (usually not required) (M3 screw) ( 2)
0.36 to 0.48 N•m
1: This terminal is used as an external power input terminal for supplying power to the
transceiver when being connected to a 10BASE5.
2: 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.
