Verify connector pin numbers, signal names, voltage levels, polarity and whether the interface is isolated. Use an appropriate converter rather than connecting RS-232 to RS-485 or applying supply voltage to a logic input.\n\nFor terminal blocks, strip conductors to the recommended length, prevent loose strands and double-check the sequence before applying power.
