2 INSTALLATION AND WIRING (FR-A700/F700 SERIES) 2.1 Pre-Installation Instructions Make sure that the input power of the inverter is off. CAUTION With input power on, do not install or remove the plug-in option. Otherwise, the inverter and plug-in option may be damaged. For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from your body.
INSTALLATION AND WIRING (FR-A700/F700 SERIES) 2.2 Installation Procedure 1)Remove the inverter front cover. 1) 2)Mount the hex-head screw for option mounting into the inverter screw hole (on earth plate). (size 5.5mm, tightening torque 0.56N⋅m to 0.
INSTALLATION AND WIRING (FR-A700/F700 SERIES) CAUTION • • • When used with other plug-in options, always connect the FR-A7AR to the connector 1 to prevent malfunction. Only one type of option per inverter may be used. When two or more options are mounted, priority is in order of inverter option connectors 1, 2 and 3, the options having lower priority are inoperative. When the inverter cannot recognize that the option is mounted due to improper Mounting Error installation, etc.
INSTALLATION AND WIRING (FR-A700/F700 SERIES) 2.3 Wiring (1) Untwist the twisted pair shielded cables after stripping its sheath. Also, perform protective treatment of the shield to ensure that it will not make contact with the conductive area. Shield (perform protective treatment) Sheath Strip off the sheath about the size as in the right figure. If the length of the sheath pealed is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off.
INSTALLATION AND WIRING (FR-A700/F700 SERIES) (2) Loosen the terminal screw and insert the cable into the terminal. Screw Size M3 Tightening Torque 0.5N⋅m to 0.6N⋅m Cable Size Screwdriver 0.3mm2 to 0.75mm2 Small flat-blade screwdriver (Tip thickness: 0.4mm/tip width: 2.5mm ) CAUTION • Undertightening can cause cable disconnection or malfunction. Overtightening can cause a short circuit or malfunction due to damage to the screw or unit.
INSTALLATION AND WIRING (FR-A700/F700 SERIES) (3) For wiring of the FR-A700 series 22K* or less and the FR-F700 series 30K* or less, route wires between the control circuit terminal block and front cover. If cables can not be routed between the control circuit terminal block and front cover due to the increased number of cables, remove a hook of the front cover and use a space become available.
INSTALLATION AND WIRING (FR-A700/F700 SERIES) REMARKS • When the hook of the inverter front cover is cut off for wiring, the protective structure (JEM1030) changes to open type (IP00). CAUTION When performing wiring using the space between the inverter front cover and control circuit terminal block, take care not to subject the cable to stress. After wiring, wire offcuts must not be left in the inverter. They may cause a fault, failure or malfunction.
3 INSTALLATION AND WIRING (FR-E700 SERIES (E kit)) 3.1 Pre-Installation Instructions Make sure that the input power of the inverter is off. CAUTION With input power on, do not install or remove the plug-in option. Otherwise, the inverter and plug-in option may be damaged. For prevention of damage due to static electricity, touch nearby metal before touching this product to eliminate static electricity from your body. 3.
