3 Wiring and Connection3.3.3 Typical Main Circuit Wiring Examples3-243.3.3 Typical Main Circuit Wiring ExamplesThe following wiring examples show the Σ-V Series SGDV SERVOPACK (Analogpulse model). Single-phase 100 V, SGDV-F (SGDV-R70F, R90F, 2R1F, 2R8F)• Use a molded-case circuit breaker (1QF) or fuse to protect themain circuit.The SERVOPACK connects directly to a commercial power sup-ply; it is not isolated through a transformer or other device.Always use a molded-case circuit breaker (1QF) or fuse to pro-tect the servo system from accidents involving different powersystem voltages or other accidents.• Install a ground fault detector.The SERVOPACK does not have a built-in protective circuit forgrounding.To configure a safer system, install a ground fault detectoragainst overloads and short-circuiting, or install a ground faultdetector combined with a molded-case circuit breaker.• Do not frequently turn power ON and OFF.• Frequently turning power ON and OFF causes elementsinside the SERVOPACK to deteriorate. Do not use the servodrive with an application that requires frequently turning powerON and OFF.• After the actual operation starts, the allowable interval for turn-ing power ON and OFF is one hour or longer.1PL: Indicator lamp1SA: Surge absorber2SA: Surge absorber3SA: Surge absorber1D: Flywheel diode1QF: Molded-case circuit breaker1FIL: Noise filter1KM: Magnetic contactor (for control power supply)2KM: Magnetic contactor (for main power supply)1Ry: RelayL1ENCSERVOPACKSGDV-FUVWM0 V1RyALM+ALM−3132 1D2KM1KMB2L2CN11QFR T1FIL+24 VB1/3SA(For servoalarm display)1Ry1PLsupply ON 1KM2KM1SAServo powersupply OFFServo power1KM1Ry1KM2SAL1CL2C
