7.5 AUTO REF: Confi gure the Frequency Reference via Remote Analog Input.
NOTICE: Equipment Damage Tighten terminal screws to specifi ed torque. Failure to comply may result in erroneous operation or
damage to the terminal block.
NOTICE: Separate the control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, p1, n1, U/T1, V/T2, W/T3). Improper
wiring practices could result in drive malfunction due to electrical interference.
Insulate shields with tape or shrink tubing to prevent contact with other signal lines and equipment. Improper wiring practices could result
in drive or equipment malfunction due to short circuit. Use shielded twisted-pair cables as indicated to prevent operating faults. Improper
wiring practices could result in drive or equipment malfunction due to electrical interference.
Connect the cable shield to the appropriate ground terminal. Improper equipment grounding could result in drive or equipment
malfunction or nuisance trips. The shield ground wire (F) is typically connected at one end, at the signal source to avoid ground loops.
Use terminal (Drive Terminal Board TB5) if a shield ground connection is required at the drive to mitigate noise issues in special cases.
7.6 Connect remote frequency reference wires to the drive control circuit terminals.
