When connecting to the power supply terminal, use the circular wiring terminal with the insulation casing (see
Figure 9.1).
Use power cord that conforms to the specifications and connect the power cord firmly. To prevent the cord
from being pulled out by external force, make sure it is fixed securely.
If circular wiring terminal with the insulation casing cannot be used, please make sure that:
•
Do not connect two power cords with different diameters to the same power supply terminal (may cause
overheating of wires due to loose wiring) (See Figure 9.2).
