Wiring Of The Main Circuit (Terminal Block Type); Wiring Method To Connector - Panasonic MINAS A5E Series Operating Instructions Manual

3. System Configuration and Wiring
(Terminal block type)
Wiring of the Main Circuit
F-frame, 200 V type
• Wiring should be performed by a specialist or an authorized personnel.
• Do not turn on the power until the wiring is completed.
• Never touch the terminal to which high voltage is applied. There is a risk of electric
shock.
• Tips on Wiring
1) Take off the cover fixing screws, and detach the terminal cover.
2) Make wiring
Use clamp type terminals of round shape with insulation cover for wiring to the ter-
minal block. For cable diameter and size, refer to "Driver and List of Applicable Pe-
ripheral Equipments" (P.B14).
Tighten the terminal block screw with a torque between 1.0 and 1.7 N
3) Attach the terminal cover, and fix with screws.
Tighten the screw securing the cover with a torque written on P.B15.

•
• Check the name plate of the driver for power
specifications.
• Provide a residual current device. The residual current
device to be the one designed for "Inverter" and is
equipped with countermeasures for harmonics.
• Provide a circuit breaker.
• Make sure to provide a noise filter.
• Provide coil surge suppression units to the coil of the
Magnetic Contactor recommended by manufacturer.
Never start/stop the motor with this Magnetic
Contactor.
• Provide an AC Reactor.
• Don't disconnect the short bar between B1 and B2.
Disconnect this only when an external regenerative
register is used.
• Do not connect anything to NC.
• Match the colors of the motor lead wires to those of the
corresponding motor output terminals (U,V,W).
• Avoid shorting and grounding.
Don't connect the main power.
• Earth-ground this.
• To prevent electric shock, be sure to connect the ground
terminal ( ) of the driver, and the ground terminal
(ground plate) of the control panel.
• The ground terminal ( ) must not be shared with other
equipment.
Two ground terminals are provided.
• Don't connect the earth cable to other inserting slot,
nor make them touch.
• Compose a duplex Brake Control Circuit so that the
brake can also be activated by an external immediate
stop signal.
• The holding Brake has no polarity.
• For the capacity of the holding brake and how to use it,
refer to P.B43, "Specifications of Built-in Holding Brake".
• Provide a varistor.
• Connect a 10 A fuse in series with the varistor.

3. System Configuration and Wiring

Wiring method to connector

• Follow the procedures below for the wiring connection to the Connector XA , XB and XC .
How to connect
1. Peel off the insulation cover of the cable.
• For single wire (Please obey the length in figure.)
• For stranded wires (ferrules must be used as illustrated below).
Example: Ferrules with plastic insulating sleeve (AI series, Phoenix Contact, Ltd.)
1) Peel off the sheath so that the conductor portion of the cable will protrude from
the tip of the ferrule. (It should protrude
1 mm or more from the ferrule.)
2) Insert the cable into the ferrule and crimp
it with an appropriate crimping tool.
3) After crimping, cut off the cable conductor
portion protruding from the ferrule. (The
allowable protruding length after cutting
should be 0 to 0.5 mm.)
• Part No. of the crimping tool:
CRIMPFOX U-D66 (1204436)
Available from Phoenix Contact, Ltd.
Examples: Nylon-insulated ferrule (NTUB series, J.S.T. Mfg. Co., Ltd.)
Vinyl-insulated ferrule (VTUB series, J.S.T. Mfg. Co., Ltd.)
1) Peel off the sheath of the cable conduc-
tor portion to the length equal to that of
sheath on the ferrule.
2) Insert the cable into the ferrule and crimp
it with an appropriate crimping tool.
• Part No. of the crimping tool: YNT-1614
Available from J.S.T. Mfg. Co., Ltd
<Cables Compatible with Connector>
Conductor Size AWG18 to 12
Sheath Outline φ2.1 to φ4.2 mm
<Recommended Connector Bar Terminal>
Conductor Size AWG18
Terminal Model Number AI0.75-8GY (Phoenix Contact, Ltd.)
Conductor Size AWG16 to 14
Terminal Model Number VTUB-2 or NTUB-2 (J.S.T. Mfg. Co., Ltd)
• When peeling off the sheath of the cable, take care not to damage
Caution
other portions.
• When crimping the ferrule, sufficiently check the status of the ferrule
and cable. If the conductors of the cable stick out from the insulation
cover or protrude excessively from the tip of the ferrule, accidents such
as an electric shock and fire from a short circuit may result.
