Connection of local power supply unit
Considering various conditions (total current consumption, voltage drop, etc.), if you judge that a local power
supply unit is necessary for the
S-LINK V
system, connect a local power supply unit.
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 power supply circuit.
●
Do not connect the main power supply to the local power supply, or connect two local power sup-
plies.
●
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.
●
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.
DANGER
Local power supply to system
Supply local power to the
S-LINK V
system from the I/O terminal or a commercial junction terminal block.
Be sure to supply stabilized power (24V DC ±10%).
