Shindaiwa DG1000MI manual Electrical damages

Caution

:Electrical damages

￿If the load exceeds the allowable amperage, the overheating may damage the cable.

￿If the cable is either too long or too small a gauge, there will be greater voltage drop to loads, which may result in reduced performance in the connected loads, malfunction, or damages.

<Caution>

￿It is recommended to select the proper gauge and length of cable, with consideration of the maximum 5% marginal drop only for the rated voltage, between the terminals of loads and generator via the cables.
