5.2.3. How to measure the insulation resistance
z
Turn off power before opening the flow transmitter cover.
z
Arresters are connected to each of power terminals (N, L) in standard, and arresters can be connected to
each of output terminals (Iout, DO1, DO2) optionally. Before measuring the insulation resistance
between a power terminal and grounding terminal, remove the grounding plate from inside the terminal
box as illustrated below. Before measuring the insulation resistance between each of the said output
terminals and grounding terminal (GND), remove an arrester board, if installed.
z
The insulation resistance performance is 100 M
:/500 V DC.
z
After the end of test, return the grounding plate and arrester board in place.
