The location of theoutputs depends on the adjustable frequencydrive 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 theadjustable frequency drive for ease of installation, asshown in Figure 4.25.130BD546.112110 mm[0.4 inches]12 13 18 19 27 29 32 33Figure 4.25 Connecting Control WiresNOTICE!Keep 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.2. 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 reduced performance.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 (Terminal27)A jumper wire may be required between terminal 12 (or13) and terminal 27 for the adjustable frequency drive tooperate when using factory default programming values.• Digital input terminal 27 is designed to receive 24V DC external interlock command.• 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 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.NOTICE!The adjustable frequency drive cannot operate without asignal on terminal 27, unless terminal 27 is re-programmed.4.8.4 Voltage/Current Input Selection(Switches)The analog input terminals 53 and 54 allow setting ofinput signal to voltage (0–10 V) or current (0/4–20 mA).Default parameter setting:• Terminal 53: Speed reference signal in open-loop(see parameter 16-61 Terminal 53 Switch Setting).• Terminal 54: Feedback signal in closed-loop (seeparameter 16-63 Terminal 54 Switch Setting).Electrical Installation Instruction ManualMG34U422 Danfoss A/S © 06/2015 All rights reserved. 334 4
