Wiring the Control Circuit Terminal
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, r1/ 11, 1/ 21, t1/ 31, , ) and other
high-power lines. Improper wiring practices could result in regenerative unit malfunction due to electrical interference.
NOTICE:
Separate wiring for digital output terminals MA, MB, MC, M1 and M2 from wiring to other control circuit lines. Improper wiring
practices could result in regenerative unit 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 regenerative unit 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 regenerative unit 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
regenerative unit or equipment malfunction or nuisance trips.
Wire the control circuit only after terminals have been properly grounded and main circuit wiring is complete.
Prepare the ends of the control circuit wiring as shown in
. Refer to
for the treatment of the ends
of the shield wire.
NOTICE:
Do not tighten screws beyond the specified tightening torque. Failure to comply may result in erroneous operation, damage
to the terminal block, or cause a fire.
NOTICE:
Use shielded twisted-pair cables as indicated to prevent operating faults. Failure to comply may cause electrical interference
resulting in poor system performance due to improper wiring practices. Use shielded, twisted-pair cables and ground the shield to the
shield ground terminal E (G) of the regenerative unit.
Connect control wires as shown in
and

Figure 3.25 Terminal Block Wiring Guide
Use the space above TB2 to wire TB5, as shown in
Figure 3.24
Figure 3.26 Terminal Board Wiring Guide
For the control circuit wires, use shielded twisted-pair wires that have been prepared as shown in
.

NOTICE:
The analog signal wiring between the regenerative unit and the operator station or peripheral equipment should not exceed
50 meters when using an analog signal from a remote source. Failure to comply could result in poor system performance.
