IEC Emergency Stop with Pilz Safety RelayIncludes a redundant 4-wire emergency-stop push-buttonmounted on the front of the enclosure and a Pilz relay thatmonitors it in conjunction with the frequency converter’ssafe-stop circuit and the mains contactor located in theoptions cabinet.Safe Stop + Pilz RelayProvides a solution for the "Emergency Stop" optionwithout the contactor in F-Enclosure frequency converters.Manual Motor StartersProvides 3-phase power for electric blowers often requiredfor larger motors. Power for the starters is provided fromthe load side of any supplied contactor, circuit breaker, ordisconnect switch. Power is fused before each motorstarter, and is off when the incoming power to thefrequency converter is off. Up to 2 starters are allowed(one if a 30 A, fuse-protected circuit is ordered). Integratedinto the frequency converter’s safe-stop circuit.Unit features include:• Operation switch (on/off)• Short-circuit and overload protection with testfunction• Manual reset function30 A, Fuse-Protected Terminals• 3-phase power matching incoming mains voltagefor powering auxiliary customer equipment• Not available if 2 manual motor starters areselected• Terminals are off when the incoming power tothe frequency converter is off• Power for the fused protected terminals will beprovided from the load side of any suppliedcontactor, circuit breaker, or disconnect switch.24 V DC Power Supply• 5 A, 120 W, 24 V DC• Protected against output over-current, overload,short circuits, and over-temperature• For powering customer-supplied accessorydevices such as sensors, PLC I/O, contactors,temperature probes, indicator lights, and/or otherelectronic hardware• Diagnostics include a dry DC-ok contact, a greenDC-ok LED, and a red overload LEDExternal Temperature MonitoringDesigned for monitoring temperatures of external systemcomponents, such as the motor windings and/or bearings.Includes five universal input modules. The modules areintegrated into the frequency converter’s safe-stop circuitand can be monitored via a fieldbus network (requires thepurchase of a separate module/bus coupler).Universal inputs (5)Signal types:• RTD inputs (including PT100), 3-wire or 4-wire• Thermocouple• Analog current or analog voltageAdditional features:• One universal output, configurable for analogvoltage or analog current• Two output relays (N.O.)• Dual-line LC display and LED diagnostics• Sensor lead wire break, short-circuit, and incorrectpolarity detection• Interface setup software3.6 Electrical Installation3.6.1 Power ConnectionsCabling and FusingNOTICECables GeneralAll cabling must comply with national and localregulations on cable cross-sections and ambienttemperature. UL applications require 75 °C copperconductors. 75 and 90 °C copper conductors arethermally acceptable for the frequency converter to usein non UL applications.The power cable connections are situated as shown below.Dimensioning of cable cross section must be done inaccordance with the current ratings and local legislation.See the Specifications section for details.For protection of the frequency converter, therecommended fuses must be used or the unit must bewith built-in fuses. Recommended fuses can be seen in thetables of the fuse section. Always ensure that proper fusingis made according to local regulation.The mains connection is fitted to the mains switch if this isincluded.3 Phasepowerinput130BA026.1091 (L1)92 (L2)93 (L3)95 PEIllustration 3.53 Power Cable ConnectionsHow to Install VLT AQUA Drive FC 202 Operation Instructions42 MG20P402 - Rev. 2013-12-1633
