20. FG Frame Ground with the thickest and shortest wire possible The wire length must be 30 cm 11 18 in or shorter The LG and FG terminals function is to pass the noise generated in the PC system to the ground so an impedance that is as low as possible must be ensured As the wires are used to relieve the noise the wire itself carries a large noise content and thus short wiring means that the wire is prevented from acting as an antenna A long conductor will become a highly efficient antenna at high frequency 9 EMC DIRECTIVE AND LOW VOLTAGE INSTRUCTION MELSEC A 2 The earth wire led from the earthing point must be twisted with the power supply wires By twisting with the earthing wire noise flowing from the power supply wires can be relieved to the earthing However if a filter is installed on the power supply wires the wires and the earthing wire may not need to be twisted 3 Except for A1S61PEU and A1S62PEU short between FG and LG terminals by a short jumper wire 9 1 2 3 Cables The cables led from the control cabinet contain a high frequency noise element and outside the control panel these cables act as antennae and radiate noise The cables connected to input output modules or special modules which leave the control panel must always be shielded cables Mounting of a ferrite core on the cables is not required excluding some models but if a ferrite core is mounted the noise radiated through the cable can be su

This chapter describes the procedure for loading and installation and gives relevant precautions to ensure that the system performs with high reliability and that its functions are used to best effect 8 1 Safety Consideration When the power to the system is turned ON or OFF the process output may not perform normally at times due to the difference between the delay time and the rise time of the power supply of the PC CPU main module and the external power supply especially DC Also if there is an error in the external power supply the output process may malfunction For example if the power supply to the PC is switched on after switching on the external power supply for the sequence program operation at a DC output module the DC output module may temporarily output erroneous signals when the power to the PC is switched on A circuit that allows the power to the PC to be switched on first must therefore be provided In addition if there is an abnormality in the external power supply or trouble in the PC this could cause malfunction To a prevent erroneous operation of the entire system and b ensure safety prepare circuits such as an emergency stop circuit protection circuit and interlock circuit that prevent machine damage and or accidents due to erroneous operation of peripheral devices An example system design circuit based on this concept is shown on the following page Some types of AnS series output module detect a blo
