4.2.2 Insulating barrier (Non-hazardous area) Specifications of a recommended insulating barrier (safety barrier) paired with the KJ16 pressure transmitter are shown in the table below. An insulating barrier does not need to be grounded as defined in the intrinsically safe standards as it is isolated from the intrinsically safe circuit.

*1 If insulating barrier is used, provide an earth ground through the piping, since it is required to obtain an earth ground from the KJ16 main unit (fitting part). In the unlikely event that earth grounding from the piping is impossible, use the shielded wire to make an earth ground. However, if both the KJ16 main unit and the shielded wire are grounded, make a 1-point grounding so as not to generate a potential difference.
