Sectional view of mounting base (side) Sectional view of installation base (front) (3) Gutter requirements G-MAX adopts the bottom cable entry method. To prevent foreign objects from entering, there is no cable entry hole on the side of the G-MAX cabinet. The cables must be entered through the trench. Therefore, a trench must be preset on site.
● The trench needs to have necessary waterproof and moisture-proof design to prevent the cables from aging and short-circuiting, which will affect the normal operation of G-MAX. ● Since G-MAX has a large power, the required cables are thicker, so the cross-sectional area of the cables must be fully considered when designing the trench.
