Static electricity
-Before touching the unit, always touch a grounded piece of metal in order to discharge static electricity.
-In dry locations, excessive static electricity can cause problems.
Wiring the Power Supply to the Control Unit
-Use a power supply wire that is thicker than 2 mm2 (AWG14), and twist it.
-The unit has sufficient noise immunity against the noise generated on the power line.
However, it is recommended to take measures for reducing noise such as using a isolating transformer
before supplying the power.
-Allocate an independent wiring for each power supplying line, input/output device and operating device.
-If using a power supply without a protective circuit, power should be supplied through a protective
element such as a fuse.
-Be sure to supply power to a control and an expansion units from a single power supply.
Turning on/off of the power of all the units must be conducted simultaneously.
Power supply sequence
In order to protect the power supply sequence, make sure to turn off the control unit before the
input/output power supply. If the input/output power supply is turned off before the control unit, or if the
control unit is not shut off momentarily, the controller detects change of input level, and might conduct an
unexpected operation.
Before turning on the power
When turning on the power for the first time, be sure to take the precautions given below.
When performing installation, check to make sure that there are no scraps of wiring, particularly
-
conductive fragments, adhering to the unit.
Verify that the power supply wiring, I/O wiring, and power supply voltage are all correct.
-
Sufficiently tighten the installation screws and terminal screws.
-
Set the mode selector to PROG. Mode.
