(6) Wiring
•
Wiring I/O wires with high voltage cable or power supply line can cause malfunction or disorder.
•
Be sure that any wire does not pass across during input LED(I/O status will not be clearly identified).
•
If an inductive load has been connected to output part, connect parallel surge killer or diode to a load. Connect the cathode of
diode to the ‘+’ part of the power supply.
(7)
Be cautious that strong shock does not applied to the I/O part.
(8) Do not separate the PCB from its case
.
2) Mounting instructions
The following explains instructions for mounting the PLC onto the control panel.
(1) Allow sufficient distance from upper part of the Unit for easy module replacement and ventilation.
(2) Make sure that GM7U is installed in figure below for most effective heat radiation.
(3) Do not mount the base board together with a large-sized electromagnetic contact or no-fuse breaker, which produces vibration,
on the same panel. Mount them on different panels, or keep the unit or module away from such a vibration source
