ACQ550-U1 User’s Manual 289Technical dataControl connectionsControl connection specificationsControl cablesGeneral recommendationsUse multi-core cables with a braided copper wire shield, temperature rated at 60 °C(140 °F) or above:For digital and analog I/O cables, twist the shield together into a bundle (pig-tail) notlonger than five times its width and connect it to terminal X1-1 at the drive end.Leave the other end of the cable shield unconnected.For connecting the shield wires of the RS485 cable, see the instructions (and notes)in section Mechanical and electrical installation – EFB on page 179.Route control cables to minimize radiation to the cable:• Route as far away as possible from the input power and motor cables (at least20 cm [8 in]).• Where control cables must cross power cables, make sure they are at an angleas near 90° as possible.• Stay at least 20 cm (8 in) from the sides of the drive.Use care in mixing signal types on the same cable:• Do not mix relay-controlled signals using more than 30 V and other controlsignals in the same cable.• Run relay-controlled signals as twisted pairs (especially if voltage > 48 V). Relay-controlled signals using less than 48 V can be run in the same cables as digitalinput signals.Control connection specificationsAnalog inputs andoutputsSee section Control terminals table on page 24.Digital inputs Digital input impedance 1.5 kohm. Maximum voltage for digital inputs is30 V.Relays(digital outputs)• Max. contact voltage: 30 V DC, 250 V AC• Max. contact current / power: 6 A, 30 V DC; 1500 VA, 250 V AC• Max. continuous current: 2 A rms (cos  = 1), 1 A rms (cos  = 0.4)• Minimum load: 500 mW (12 V, 10 mA)• Contact material: Silver-nickel (AgN)• Isolation between relay digital outputs, test voltage: 2.5 kV rms, 1 minuteCable specifications See section Control terminals table on page 24.Double shielded Single shieldedExample: JAMAK by Draka NK Cables Example: NOMAK by Draka NK Cables
