Many shunts are designed for the positive line. However, a compelling safety argument exists for placing the shunt in the negative (ground) line if your system is DC negative‑ground (typical of most vehicles and solar installations). The large metal body of the shunt becomes a potential short‑circuit hazard if placed on the positive side; placing it on the negative side eliminates that danger because any accidental contact with ground simply makes the meter inaccurate rather than causing a dead short across the battery. Choose whichever method is clearly described in the documentation supplied with your unit, but if you have a choice, the negative‑side placement is safer.
