The cable connected to the PT has a functional ground terminal (FG)
Wire them according to the conditions described below.
1. If there is a ground potential difference between the NSH5 and the host,
2. If the PT is installed in the same panel as a source of noise, such as a mo-
Be sure to ground correctly to prevent malfunctioning due to noise.
(2) Use a DC power supply with little voltage fluctuation.
(3) Do not perform a dielectric strength test.

Class 2 power supply refers to one in which the current and voltage levels
of the product’s secondary output are both limited (100 VA max.), and
which has undergone and passed the necessary tests for UL certification.
