PRE-OPERATION INSTRUCTIONS Unpacking and Product Confirmation Take the plug-in option out of the package, check the unit name, and confirm that the product is as you ordered and intact. This product is a plug-in option dedicated for the FR-F series. 1.1.1 Packing confirmation Check the enclosed items.
PRE-OPERATION INSTRUCTIONS 1.1.3 Specifications (1) Types of output signal 1 changeover contact output (three relays are provided) (2) Contact capacity 230VAC ..0.3A 30VDC .... 0.3A CAUTION The contacts should be used within the rated capacity to prevent contacts weld resulting from faster contacts wearing.
INSTALLATION AND WIRING 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.
INSTALLATION AND WIRING Installation Procedure 1) Remove the inverter front cover. 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 0.75N⋅m) 3) Securely fit the connector of the plug-in option to the inverter connector along the guides.
INSTALLATION AND WIRING 2.3 Wiring (1) Strip off the sheath of the cable to wire. Strip off the sheath about the size below. 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. Wire the stripped cable after twisting it to prevent it from becoming loose.
