Grid Connection Guidelines

Equipment grounding tightening torques: 4-6 AWG: 45 lb-in, 8 AWG: 40 lb-in,

10-14 AWG: 35 lb-in.

The conduits, hubs and fittings must be suited for field wiring systems.

The hubs and other fittings must comply with UL514B.

Use only copper conductors rated for a minimum of 90°C.

For the SE10KUS, SE20KUS, SE33.3KUS three phase inverters where opposite

polarity DC conductors are routed in the same conduit, 1000V rated cables must

be used.

Use the conduit and wiring appropriate for the installation location per the NEC.

Outdoor installations must use components that are rated NEMA 3R or higher.
