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.
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.
Important:
Outdoor installations require that all conduit fittings interfacing with the
PV100S be NEMA 4 rated.
