Operating Power Installation
A separate earth ground connection must be made to ensure proper panel operation and lightning
and transient protection. Remove the two keps nuts from the grounding stud in the backbox. Con-
nect the incoming earth ground wire to supplied cable #71073 with a wire nut. Position the ring ter-
minal end over the grounding stud. Secure with one of the keps nuts. Place the ring terminal from
the other supplied ground cable #71073 over the ground stud and secure with the second keps nut.
Wire the ground cable to the bottom position of TB3. Refer to the figure below for location of the
stud. Apply AC power to the panel only after the system is completely installed and visually
checked. Note that AC power must be applied to the panel before installing the battery interconnect
cable.
Secondary Power Source (batteries)
Observe polarity while connecting the battery. When installing one 12 volt battery for up to 12
Amp Hour applications, connect the supplied battery cable (P/N 75516) by sliding the connector
attached to the long red wire onto the positive (+) battery terminal and the connector attached to the
long black wire onto the negative (-) battery terminal. Tie-wrap or tape the two unused short wires
to the long wires.
When installing two 12 volt, 7 Amp Hour batteries (in parallel) for up to 14 Amp Hour applica-
tions, follow the same procedure as described for one battery except connect the unused short wires
to the second battery. Slide the connector attached to the short red wire onto the positive (+) termi-
nal of the second battery and the connector attached to the short black wire onto the negative (-)
battery terminal of the second battery.
