MIDNITE SOLAR CHARGE CONTROLLER INSTALLATION GUIDELINES AND SAFETY
INSTRUCTIONS
This product is intended to be installed as part of a permanently grounded electrical system as shown in the
system configuration sections. The following important restrictions apply unless superseded by local or national
codes:
•The System's DC Negative conductor must not be bonded to earth ground. The Classic does this with its
internal Ground Fault Protection circuitry. The battery negative and ground are not bonded together directly but
are connected together by the Classic‘s internal GFP device. All negative conductor connections must be kept
separate from the grounding conductor connections. The equipment ground terminal inside the Classic must be
connected to Earth Ground for the internal DC-GFP to work. Continue
• With the exception of certain telecom applications, the Charge Controller should never be positive grounded.
