5.9 Control WiringAll terminals to the control cables are inside the drivebelow the LCP. To access the control terminals, either openthe door (D1h/D2h/D5h/D6h/D7h/D8h) or remove the frontpanel (D3h/D4h).5.9.1 Control Cable Routing• Isolate control wiring from high-powercomponents in the drive.• Tie down all control wires after routing them.• Connect shields to ensure optimum electricalimmunity.• When the drive is connected to a thermistor,ensure that the thermistor control wiring isshielded and reinforced/double insulated. A 24 VDC supply voltage is recommended.Fieldbus connectionConnections are made to the relevant options on thecontrol card. For more detail, see the relevant fieldbusinstruction. The cable must be tied down and routed alongwith other control wires inside the unit.5.9.2 Control Terminal TypesIllustration 5.35 shows the removable drive connectors.Terminal functions and default settings are summarized inTable 5.1 – Table 5.3.130BF144.10Illustration 5.35 Control Terminal Locations12 13 18 19 27 29 32 33 20 3739696861 42 50 53 54 55130BF145.101231 Serial communication terminals2 Digital input/output terminals3 Analog input/output terminalsIllustration 5.36 Terminal Numbers Located on the ConnectorsTerminal Parameter DefaultsettingDescription61 – – Integrated RC-filter forcable shield.
