Information

The DC input and AC output circuits are isolated from the enclosure and

system grounding, as required by section 250 of the National Electric

Code, ANSI/NFPA 70. Similarly, such isolation of DC input and AC

output circuits from enclosure and system grounding is also required by

the CANADIAN ELECTRICAL CODE, PART 1. It is the responsibility

of the installer to maintain this isolation.

The Photovoltaic System Grounding shall be installed per the

requirements of sections 690.41 through 690.47 of the National Electric

Code, ANSI/NFPA 70. It is the responsibility of the installer to meet

these requirements.

AC Grounding

The Digiwatts unit must be connected to the AC ground from the utility via the

Ground Terminal. Use 8AWG-12AWG, 105°C, copper wire for AC grounding.

PV Grounding

The PV array ground should be connected to the PV Grounding and DC

Grounding Electrode Conductor. Use 8AWG-10AWG, 105°C, copper wire for PV

grounding.
