5 Main Circuit and Motor Wiring
Use this section to convert the V1000 main circuit wiring for installation to the GA500.
Key wiring differences between the V1000 and GA500 are:
• V1000 uses crimp terminals/ring lugs and GA500 accepts bare wire (except for ground terminal).
• Terminal sizes, shapes or physical location may differ slightly between V1000 and GA500.

• Wire Termination Differences V1000 to GA500 on page 13

Main Circuit Wiring Procedure

Follow the GA500 Installation & Primary Operation Manual (No. TOEPC71061752) for all wiring procedures.
NOTICE:
• A screwdriver or hexagonal tool must be used when wiring the terminal.
• When stranded wire is used, wire it so that no loose wire strands protrude out of the connection. Do not
excessively twist stranded wire.
• Do not solder wire ends.
• Do not use bent or crushed wire. Cut off any rough ends of the wire before installation.
1.
Label the V1000 terminal wires before removing.
2.
Remove crimp terminals if needed, and prepare wire ends.
3.
Expose the required length of bare wire by stripping the insulation to the strip length in
4.
Wire the terminals. The wire will correctly fit the terminal block when the insulation is stripped to expose the
correct wire length.
5.
Tighten screws according to the tightening torque listed in the GA500 Installation and Primary Operation Manual
No. TOEPC71061752.
6.
Dress and arrange wires so that excessive wire tension is not applied to the terminal block.
7.
After connecting the wires, gently pull on the wires to check that they do not pull out.
8.
Regularly tighten any loose terminal block screws to their specified tightening torque.
