Power Supply

DANGER
Observe the following items to connect a power supply unit:
● Select a power supply unit having short-circuit protective function (fuse, etc.).
● The power of the S-LINK V system passes through the inside of each unit and is then supplied to
the main cable or I/O device side. However, the short-circuit protective function is not adopted.
For this reason, adopt a short-circuit protective function, such as a fuse, for the power supply circuit.
● Before starting the wiring work, be sure to turn off the power. If the power is not turned off, the sys-
tem may be shorted or damaged, and you may get an electric shock.
● Take care that wrong wiring will damage the product.
● If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.)
terminal of the power supply is connected to an actual ground.
● Do not use during the initial transient time after the power supply is switched on. Note that if the
READY output signal of the SL-VCU1 or SL-VMC1 is off, or if the controller, control board, control
module, or handy monitor is in the BUSY mode (in the power-on or system setting), transmission
will not be possible.
● In this section, the main power supply unit means the power supply unit that activates the com-
munication and connection units of the S-LINK V system. In addition, for the control units (PLC,
personal computer, etc.) to which the S-LINK V units are connected, separate power supply units
that conform to the specifications of the control units are needed.
For a detailed description, refer to the instruction manual of each unit.
● If it takes a long time to turn on or off the power, use a timer relay so that the power can be sup-
plied after stabilization.
