Conduit Installation

Given the flexible nature of the system, conduit installation will be dependent upon the final configuration of the system. Procurement and installation of the conduit, therefore, is the responsibility of the installer. Since the layout will be dependent upon the location available for the installation and the size of the conductors used, specific conduit size and type must be pre-determined by the installer before the actual installation. See “Conductor and Conduit Sizing” on page 2–11 for instructions on how to determine the size of the conductors and conduits to be used. Once the size of the conductors and conduits has been determined, follow the instructions below for installing the conduits. Be sure to consult the NEC Handbook and any local codes to ensure code compliance.

Important: Outdoor installations require that all conduit fittings interfacing with the

PV100S be NEMA 4 rated.

To install the conduits:

1.Determine the conduit penetration locations in the Main Inverter Enclosure and the AC interface/transformer assembly. See Figure 2-3 on page 2–8 through Figure 2-5 on page 2–9.

2.Install appropriately sized conduit based upon system layout and required codes between the main inverter and the AC interface/transformer assembly. For ease of conduit installation, the access panels on both the main inverter and the AC interface/transformer assembly can be removed.

3.Determine all remaining conduit penetration locations in the AC Interface enclosure, DC Interface Enclosure, and Communication Enclosure. See Figure 2-3 on page 2–8 through Figure 2-8 on page 2–10.

4.Install all remaining appropriately sized conduit interfacing for the AC Interface Enclosure, DC Interface Enclosure, and Communication Enclosure based upon system layout and required codes.
