    		Below 1 Ω
    T1-2 (PLS1) - P4-3 (PLS)
    		Below 1 Ω
    T1-3 (PLS2) - P4-5 (PLS2)
    		Below 1 Ω
    T1-5 (SGND) - P4-6 (E)
    		Below 1 Ω
    1-8 (VCC) or P4-4 (SSRB) - Body ground
    		10 kΩ or higher
    T1-2 (PLS1) or P4-3 (PLS) - Body ground
    		10 kΩ or higher
    T1-3 (PLS2) or P4-5 (PLS2) - Body ground
    		10 kΩ or higher
