Introduction

DC Interface

DC Terminals

1–8
The DC Interface serves as the connection interface between the PV array and the
GT100 (see Figure 1-2 on page 1–4 to locate the DC Interface). This section
houses the DC Disconnect Switch and DC contactor. Additionally, the PV Ground
Fault Detection circuitry, DC surge arrestor, Solid State Relays, and 48Vdc Power
Supply are also housed in this section.

The terminals provide space for six holes with space for twelve cables with a M10
bore diameter per pole (see Table A-6 on page A–5 for torque requirements).
The table below describes the DC terminal polarity for each GT100 model.
