4.2 Permanent Storage The method for storing the option over a long period after purchase due to no schedule of operation varies according to the environment of the storage site. If strict storage is necessary, specify the concrete environment specification and contact the dealer or nearest Fuji's sales office. The general storing method is described below. -
Page 10: How To Install
5.2 How to Install •Turn OFF the breaker on the power supply side of the converter before you mount/dismount this option. • When the breaker is OFF, a smoothing capacitor is still charged and touching it will cause an CAUTION electric shock. - Page 11 B．How to install the Communication Option Following restrictions are applied to installing this option. ♦ Install this option card in either of two installation positions (CN2 on the left side or CN3 on the right side) on the control board while referring to "(a) Installation Method 1-1" described below. However, if an analog card is installed on the same control board, be sure to install the option card at CN2 and install the analog card at CN3.

Page 12: Connection
6 Connection See the Instruction manual (INR-HF51746*-E) of the converter for mounting/dismounting the front cover ▪Improper wiring operation causes disasters such as electric shock and fire. A specialist should conduct the wiring. Turn OFF the breaker on the power supply side when you touch the electric circuit for wiring operation after power is supplied. -
Page 13: Connecting Optical Fiber Cables
When installing the option unit, take due consideration on light shielding, for example, storage into a control board. Use the optical fiber cable included in the converter to connect the OPC-VG7-SI card on the individual converters. The optical fiber cable has plugs in different colors, gray and blue on each side. Connect them to the connectors with the same colors on the individual cards. -
Page 14: Switching Parallel System Driving/ Single Driving
You can use the external digital input signal [OPT-DI] to cancel parallel system operating with high-speed serial card ”OPC-VG7-SI”, and then it could be changed single system by 1 unit driving. It uses as an urgent backup to decrease the load only with the normal converter when the converter that composes parallel system breaks down and to continue driving. -

Page 20: Optical Network Error（Erb
9.1 Optical Network Error（Erb） When an optical fiber cable is disconnected or disengaged from a connector, all units become an alarm state due to the optical network error (Erb). If the external alarm condition of the inverter is a converter alarm output, the inverter becomes an alarm state, and the motor stops after coasting You cannot reset the alarm state if you enter a reset command (KEYPAD panel, terminal, communication) while the cause of the alarm is not removed. -
