3 WIRING 3.1 System Configuration Example (1) Mount the communication option (FR-A7NL) on the inverter. (Refer to page 7.) (2) Connect the LONWORKS node, option unit, network management + computer, and terminating resistor with the cable for LONWORKS C1 communication. Minimum 100 F, 50V(min) Select a terminating resistor so that resistance values of R of the RC R network are the same as shown below. ⋅ Free topology (Refer to page 6) ......................... R = 52.
WIRING 3.2 Wiring (1) Strip off the sheath of the cable for LONWORKS communication. If the length of the sheath peeled is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off. Cable stripping size Wire the stripped cable after twisting it to prevent it from becoming loose. (Do not solder it.) Use a bar type terminal as required.
WIRING (2) Loosen the terminal screw and insert the cable into the terminal. Tighten the fastening screws to the recommended tightening torques. Leave the other end of the cable unconnected. Screw Size Tightening Torque Cable Size Screwdriver M3 0.5N⋅m to 0.6N⋅m 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.
WIRING NET_A 16 NET_B (3) Connect the terminal block to the connector for communication of the communication option.
WIRING (4) When wiring, if a hook of the front cover of the plug-in option impedes wiring, cut off the hook and perform wiring. Cut off with a nipper, etc. Cut off a hook at the bottom of the option cover. (Cut off so that no portion is left.) REMARKS • When the option protective cover is not fitted or wire is not passed through even if the hook of the front cover of the plug-in option has been cut off, the protective structure (JEM1030) changes to open type (IP00).
WIRING (5) For wiring of FR-E720-5.5K (FR-E720-240) or more and FR-E740-11K (FR-E740-230) or more, pass a cable on the inverter front cover as shown below. If a cable for LONWORKS communication is passed through inside the inverter front cover, the bending radius of the cable becomes small, stressing the cable. CAUTION When wiring, 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.
