Location of the outputsdepends on frequency converter configuration.• Terminals on built-in optional equipment. See themanual provided with the equipment option.4.8.2 Wiring to Control TerminalsControl terminal connectors can be unplugged from thefrequency converter for ease of installation, as shown inIllustration 4.10.NOTICEKeep control wires as short as possible and separatefrom high-power cables to minimize interference.1. Open the contact by inserting a small screwdriverinto the slot above the contact and push thescrewdriver slightly upwards.130BD546.112110 mm[0.4 inches]12 13 18 19 27 29 32 33Illustration 4.10 Connecting Control Wires2. Insert the bare control wire into the contact.3. Remove the screwdriver to fasten the control wireinto the contact.4. Ensure that the contact is firmly established andnot loose. Loose control wiring can be the sourceof equipment faults or less than optimaloperation.See chapter 8.5 Cable Specifications for control terminalwiring sizes and chapter 6 Application Set-up Examples fortypical control wiring connections.4.8.3 Enabling Motor Operation(Terminal 27)A jumper wire is required between terminal 12 (or 13) andterminal 27 for the frequency converter to operate whenusing factory default programming values.• Digital input terminal 27 is designed to receive24 V DC external interlock command.• When no interlock device is used, wire a jumperbetween control terminal 12 (recommended) or13 to terminal 27. The jumper provides aninternal 24 V signal on terminal 27.• When the status line at the bottom of the LCPreads AUTO REMOTE COAST, it indicates that theunit is ready to operate but is missing an inputsignal on terminal 27.• When factory installed optional equipment iswired to terminal 27, do not remove that wiring.Electrical Installation Operating GuideMG20MD02 Danfoss A/S © 10/2016 All rights reserved. 214 4
