(2) Input power requirements
It is recommended that the PLC and CM terminals on the FRENIC-Multi be used for the power supply
terminal block. When using an external power source, however, select the input power supply that meets
the specifications listed in Table 4.3.
Table 4.3 Input Power Requirements

Specifications
Input power voltage range
21.6 to 27.0 V
Power consumption
Maximum 35 mA
Do not use the 24 V power supply designed for DeviceNet communication (i.e., power supply fed
to the DeviceNet cable) for the power supply terminal block. Doing so may affect negatively on the
noise resistance in DeviceNet communication.
It is convenient to use the PLC terminal on the control circuit terminal block on the FRENIC-Multi
as a 24 V power supply. Connect the PLC terminal to the "24 V" terminal of this option, and the CM
terminal, to the "0 V" terminal.
For details about the PLC and CM terminals, refer to the FRENIC-Multi Instruction Manual
(INR-SI47-1094-E), Chapter 2, Section 2.3 "Wiring."
4.3 Wiring for DeviceNet Terminal Block
(1) To connect this option to DeviceNet, use a DeviceNet thin cable complying with the DeviceNet
specifications. Also observe the wiring lengths specified in the DeviceNet specifications.
The recommended DeviceNet cable is TDN24U made by SWCC Showa Device Technology, Co.,
Ltd.
Proper installation of the cable requires specialist knowledge. Be sure to refer to the DeviceNet
specifications (published by ODVA) beforehand.
(2) Wiring around the DeviceNet terminal block (TERM1)
The terminal block uses a pluggable 5-pin connector as shown in Figure 4.4. It has five labels
corresponding to the five pins. Each label has an ID color corresponding to the wire (core) to be connected
to its pin. Make sure that the ID colors of the wires and labels match. Table 4.4 shows the correspondence
between the pin numbers and the ID colors.
A typical connector that matches this terminal block is Phoenix Contact MSTB 2.5/5-ST-5.08 AU.
The Phoenix Contact TMSTBP 2.5/5-ST-5.08 AU and TFKC 2.5/5-STF-5.08 AU (spring-cage
connection type) connectors for multidrop connection are also usable. Note that, however, the
former can be used only for FRENIC-Multi 3.7 kW or below.
