Wiring the Terminal Unit
Section 3-3
Note
1.
Wire the signal lines separately from power lines to prevent noise interfer-
ence.
2.
Use crimp terminals for wiring.
Crimp Terminals
Always connect M3 crimp terminals, as shown below, when wiring the Termi-
nal Unit. Tighten to a torque of 0.40 to 0.56 N·m.
3-3-2
Wiring the Power Supply
Connect the power supply (20.4 to 26.4 VDC) for the Temperature Controllers
to terminals 19 and 20, as shown in the following diagram.
When more than one block of Temperature Controllers is used, connect a
power supply to the E5ZN-SCT24S Terminal Unit on the leftmost side of each
block.
Note This power supply is used for communications between the DeviceNet Com-
munications Unit and the Temperature Controllers (RS-485), and to start the
Temperature Controllers.
Consider the power consumption of each Temperature Controller and the con-
nected I/O when selecting a power supply.
When reinforced insulation is required, connect the I/O to a device without an
exposed charged section or to a device with basic insulation that is suitable for
the maximum usage voltage of the I/O section.
UL/CSA Safety Standards
Use a SELV power supply with overcurrent protection.
A SELV power supply has redundant I/O or increased insulation, an output
voltage of 30 Vr.m.s and a 42.4-V peak or maximum of 60 VDC.
Recommended power supply: S82K-05024CD (OMRON) or S8VS-06024A
(OMRON)
5.8 mm max.
