The diameter of cable for external power supply shall be not less than
2.5mm²
(13AWG).
Hot-line work may result in the risk of fatal electric shock, so make
sure it is uncharged when connects with external power supply and in the
case of setting the power supply mode.
8.11 Seal at the Bottom of Cabinet
In order to prevent short-circuiting of air flow inside and outside the
cabinet and to ensure the tightness of the cabinet as a whole, there is a need to
seal the threaded hole at the bottom with fire clay.
After the cabinet wiring is completed, there will be some certain gap
between the cable and leading-in hole, which will cause a short circuit inside
and outside the cabinet air flue, resulting in an adverse effect on the cooling
rack. Therefore, the gap between the leading-in hole and cable shall be sealed
to ensure tightness of the cabinet as a whole.
