System example
Field line connection
L1, L2, L3, N-phase of the power cord should be clamped to the safety catch using the included
clamp material.
The green and yellow striped wrapped wires should be used for grounding.
1. Power supply
(200 V, Three-phase)
2. Branch switch, overcurrent breaker
3. Grounding wire
4. Earth leakage breaker
5. Section A
6. Attach insulation sleeves.
7. Power supply terminal block
8. Grounding wire
9. Retain the ground wires along with the power wires using the accessory clamps (1).
10. Retain the respective power wires - L1, L2, L3 and N phases - to the bracket individually using the
accessory clamps (1).
11. Grounding wire
12. When wiring, do not allow the ground wires to contact the compressor lead wires. If the wires contact each
other, adverse effects may occur to other units.
13. When connecting two wires to one terminal, ensure that the crimp-style terminals face with each other
back to back.
Moreover, make sure that the wire of the smaller gauge is located above.
At the same time, retain the power wires to the plastic bracket using the accessory clamps (1).
14. Terminal block
