NOTICE: Separate wiring for digital output terminals MA, MB, MC and M1 to M6 from wiring to other control circuit lines. Improper
wiring practices could result in drive or equipment malfunction or nuisance trips.
NOTICE: Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2, W/T3, -, +1, +2) and
other high-power lines. Improper wiring practices could result in drive malfunction due to electrical interference.
NOTICE: Use a class 2 power supply (UL standard) when connecting to the control terminals. Improper application of peripheral
devices could result in drive performance degradation due to improper power supply.
NOTICE: Do not exceed 50 meters (164 feet ) for the control line between the drive and the operator when using an analog signal from
a remote source to supply the frequency reference. Failure to comply could result in poor system performance.
NOTICE: Do not use unshielded cable for control wiring. Failure to comply may cause electrical interference resulting in poor system
performance. Use shielded, twisted-pair wires, and ground the shield to the ground terminal of the drive.
Wire the control circuit only after terminals have been properly grounded and main circuit wiring is complete. Refer to
Figure 3.14 and Figure 3.15 for details. Prepare the ends of the control circuit wiring as shown in Figure 3.16 . Refer to
Wire Size on page 56 .
NOTICE: 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 control wires as shown in Figure 3.14 :
Figure 3.15
Figure 3.14 Terminal Board Wiring Guide
To disconnect control wires from the terminals use the procedure described in Figure 3.15 . Grasp the wire where it
enters the terminal with a pair of pliers, then use a straight-edge screw driver to release the terminal and pull the wire out.
If it fits tightly, e.g. if ferrules are used, turn the wire for about 45
°
and then pull it gently out. Use this procedure to
remove the wire jumper between terminals HC and H1 that is preinstalled at shipping.
