Location of the outputsdepends on frequency converter configuration.• Terminals located on built-in optional equipment.See the manual provided with the equipmentoption.4.8.2 Wiring to Control TerminalsControl terminal connectors can be unplugged from thefrequency converter for ease of installation, as shown inIllustration 4.7.NOTICEKeep control wires as short as possible and separatefrom high power cables to minimise interference.1. Open the contact by inserting a small screwdriver into the slot above the contact and pushthe screw driver slightly upwards.130BD546.102110 mm2927 321918131233Illustration 4.9 Connecting Control Wires2. Insert the bared control wire into the contact.3. Remove the screw driver to fasten the controlwire into the contact.4. Ensure the contact is firmly established and notloose. Loose control wiring can be the source ofequipment faults or less than optimal operation.See 8.5 Cable Specifications for control terminal wiring sizesand 6 Application Set-up Examples for typical control wiringconnections.4.8.3 Enabling Motor Operation (Terminal27)A jumper wire may be required between terminal 12 (or13) and terminal 27 for the frequency converter to operatewhen using factory default programming values.• Digital input terminal 27 is designed to receive an24 V DC external interlock command. In manyapplications, the user wires an external interlockdevice to terminal 27.• When no interlock device is used, wire a jumperbetween control terminal 12 (recommended) or13 to terminal 27. This provides an internal 24 Vsignal on terminal 27.• When the status line at the bottom of the LCPreads AUTO REMOTE COAST, this indicates thatthe unit is ready to operate but is missing aninput signal on terminal 27.• When factory installed optional equipment iswired to terminal 27, do not remove that wiring.NOTICEThe frequency converter cannot operate without a signalon terminal 27 unless terminal 27 is re-programmed.Electrical Installation VLT® AQUA Drive FC 202 Operating InstructionsMG20MA02 - Rev. 2013-10-29 174 4
