What are the specifications, including the diameter, for the 15-meter cable used with the Power Pack?

The standard cable for the Power Pack is 0.75mm with a 2 x 7 configuration. However, if an extension is required, the cable's size should be increased to at least 1mm² to 1.5mm², depending on the extension length. This increase in core size is necessary to counteract voltage drop when extending the cable run.
