Installation
Recommended Tools:
• Wire strippers
• Wire cutters
• #2 & #0 Phillips screwdriver
• slotted screwdrivers
• Pliers
• Drill3/32” (2.5 mm) drill bit
• Level
• hack saw (cutting conduit)
3.2 Wiring Zones
The 600V solar circuits must be separated from the low voltage battery circuits and communica-
tion wiring within the wiring box. Figure 3-1 below shows the high voltage and low voltage zones
(shaded) within the wiring box. There is overlap in the zones as pictured because the removable
wiring divider separates the high voltage solar wiring and low voltage wiring. Solar high voltage
wiring should be routed below the removable wiring divider. The yellow
Solar Terminal Bridge
must be properly fitted in place before making the solar power terminal connections.
The battery wiring and all communication cables must only be routed within the low voltage wir-
ing zone. After the solar wiring is installed, the wiring divider should be secured in place, and the
battery cables routed above the divider. Detailed installation steps are provided in the following
sections.
NOTE:
If ALL field wiring, including communications cable, is rated for 600V, wiring zone separation is
not required. In this case, it may be more convenient to remove the high-low voltage wiring box divider,
and terminate conduit that contains mixed voltage conductors at one point
.
