(PVI-3.8/4.6-I-OUTD-US Rev.: 1.1)
The -US-xx models are supplied without a switch box and therefore without a 600V
integrated switch.
The -PG models are supplied with positive input grounded fig.1a (to be used only in
parallel mode).
The -NG models are supplied with negative input grounded fig.1b.
WARNING: The electrical schematics in Fig. 13 shows -NG models. In that
case the switch will physically disconnect only the positive DC inputs while
the negative are always grounded by the fuse. For -PG models the switch will
physically disconnect only the negative DC inputs while the positive are
always grounded by fuse.
