Connecting the Power Supply Cables
Section 4-2
4-2
Connecting the Power Supply Cables
You connect the power supply cables to the power supply terminals on the
CompoNet Communications Unit. Network power is not necessary if you con-
nect the Communications Unit to a host network.
4-2-1
Types of Power Supply
You must connect two types of power supply to the CompoNet Communica-
tions Unit.
■
Unit Power Supply
The Unit power supply is for the internal circuits in the CompoNet Communi-
cations Unit and connected SmartSlice I/O Units. The connectors on the Base
Blocks send the power to the SmartSlice I/O Units.
■
I/O Power Supply
The I/O power supply is for the external I/O devices which connect to the
SmartSlice I/O Units. The connectors on the Base Blocks send the power to
the SmartSlice I/O Units.
4-2-2
Recommended Power Supplies
Use an SELV power supply with overcurrent protection.
An SELV power supply has redundant or reinforced insulation between the I/
O, an output voltage of 30 Vr.m.s and a 42.4-V peak or maximum of 60 VDC.
We recommend these Power Supplies.
• S82K-10024 (from OMRON)
• S82J-10024D (from OMRON)
4-2-3
Power Supply Terminals
The power supply terminals on the CompoNet Communications Unit and
Turnback Units are screwless clamp terminals. If you connect ferrules on the
wires, all you must do to connect the wires is to push the ferrules into the ter-
minals.
