INSTALLATION AND WIRING

2.2.4 Connection to the PU connector

(1) When connecting the operation panel or parameter unit using a cable

Use the option FR-CB2 or the following connector and commercially available

cable:

• Connector: RJ45 connector

Example: 5-554720-3, Tyco Electronics Corporation

• Cable: :Cable conforming to EIA568 (e.g. 10BASE-T cable)

Example: SGLPEV-T 0.5mm×4P (Twisted pair cable, 4 pairs),

MITSUBISHI CABLE INDUSTRIES, LTD.

Note: The rear cover and junction adaptor are required since the circuit board is

exposed in the back of the operation panel. Use the FR-E5P option (cover and

adaptor available as a set).

• Operation panel: 20m

• Parameter unit (FR-PU04): 20m

(2) For RS-485 communication

With the operation panel disconnected, the PU

connector can be used for communication operation

from a personal computer etc.

When the PU connector is connected with a personal,

FA or other computer by a communication cable, a

user program can run and monitor the inverter or read

and write to the parameters.

Viewed from the inverter (receptacle side) front

Note: 1. Do not connect the PU connector to a computer's LAN board, FAX modem

socket or telephone modular connector. The product could be damaged

due to differences in electrical specifications.

2. Pins 2) and 8) (P5S) provide power to the operation panel or parameter

unit.

Do not use these pins for RS-485 communication.

3. Refer to page 144 for the communication parameters.
