Chassis Grounding
In all installations the Classic chassis should be connected to ground. For systems with a battery breaker
sized 60 amps and smaller, 10 AWG (6 mm
2
) copper is generally sufficient. For systems with a battery
breaker sized 100 amps and smaller, 8 AWG (10 mm
2
) copper is required. For grounding conductor
requirements on your specific installation please consult your local electrical code.
The chassis
grounding terminal is in the upper right corner of the electrical connection compartment.

DC System Grounding
The Classic charge controller is designed to work with Negative Ground, Positive Ground or Ungrounded
power systems. In grounded systems, dc negative may be connected to ground either externally or by
using the Classic’s internal grounding jumper, shown on figure 11 on Page 22. The internal grounding
jumper should only be installed when the Classic’s GFP is enabled.
In Positive ground or Ungrounded systems the GFP jumper must be removed. See Figure 15 Also note that
with Positive ground there will be items still referenced to battery negative that can complete a short
circuit of the battery bank, these items include, but are not limited to, the USB Cable and RS232 serial
data lines.
