INSTALLATION AND WIRING

2.2.6 Connection to the PU connector

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

• Parameter unit connection cable (FR-CB2 ) (option) or the following connector and cable available on the

market

• Connector : RJ45 connector

Example: 5-554720-3 of Tyco Electronics Corporation

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

Example:

SGLPEV-T 0.5mm x 4P(twisted pair cable, 4 pairs) of Mitsubishi Cable Industries, LTD.

• Maximum wiring length : 20m

(2) For computer link communication

Using the PU connector, you can perform 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 parameters.

Refer to the Instruction Manual (detailed) for details.

• Conforming Standard : EIA-485 (RS-485)

• Transmission form : Multidrop link

• Communication speed : Maximum 19200bps

• Overall length : 500m

2.2.7 Earthing (Grounding) precautions

z Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed

(grounded). Earthing (Grounding) must conform to the requirements of national and local safety regulations and

electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards.)

z Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not use the screw in the case,

chassis, etc.)

Use a tinned* crimping terminal to connect the earth (ground) cable. Tighten the screw, taking care not to break

its threads.

*Plating should not include zinc.

z Use the thickest possible earth (ground) cable. Use the cable whose size is equal to or greater than that indicated

below, and minimize the cable length. The earthing (grounding) point should be as near as possible to the

inverter.

For use as a product compliant with the Low Voltage Directive, use PVC cable whose size is indicated within

arentheses.

z Earth (Ground) the motor on the inverter side using one wire of the 4-core cable.

CAUTION

Do not connect the PU connector to the computer's LAN board, FAX modem socket or telephone

connector. The product could be damaged due to differences in electrical specifications.
