Wiring the Control Circuit Terminal
u
This section describes the proper procedures and preparations for wiring the control terminals.
WARNING! Electrical Shock Hazard. Do not remove covers or touch the circuit boards while the power is on. Failure to comply could result
in death or serious injury.
NOTICE: Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2, W/T3,
other high-power lines. Improper wiring practices could result in drive malfunction due to electrical interference.
NOTICE: Separate wiring for digital output terminals MA, MB and MC from wiring to other control circuit lines. Improper wiring practices
could result in drive or equipment malfunction or nuisance trips.
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: 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.
NOTICE: Connect the shield of shielded cable to the appropriate ground terminal. Improper equipment grounding could result in drive or
equipment malfunction or nuisance trips.
Wire the control terminals using
