Chapter3 Mounting and Precautions 3.1 Mounting ・Take care to act on the following points when the CPU link module is mounted. Confirm the following two points when mounting or dismounting the CPU link module. Check the connections of the CPU link module’s connector in basic base side. If there are any problems, contact nearest after-sales service station or your dealer.
3.2 Precautions ・Make connection and disconnection of the coaxial cable or optical cable in the state where the power is OFF for the base on which the link module is mounted. ・Carry out mounting / dismounting of the link module in the state where the power is OFF for the base on which the link module is mounted.
● Precautions of Optical CPU link module (OLINK-SH) ・When the power source of the base on which the optical link module is mounted, is turned off, the link system usually goes down. In order to avoid system down, supply external non-outage 5 V DC input terminal table of bypass cassette.

supplier. (3) Use shield line to connect power supply to the module, isolating from other cables (for I/O, etc.). (Ground the shield line on the power side.) (4) Power supply line for external supply to the module: 0.75 mm or more in sectional area, 1 m long max. (5) Avoid occurring noise in the 5 V DC line by installing a noise filter in the AC/DC line of the constant-voltage power supply for external supply.
For preventing termination of linking operation at the time of power OFF of the link system, therefore, turn OFF the power for a station at a time. (4) If overlap of station numbers is present, the following operation may occur depending on the timing of power ON at the time of activation of the link system.
