Intended use

The NGRM700 is only intended for use in high-resistance grounded systems. In these systems, the
NGRM700 monitors
• the current through the neutral-grounding resistor (NGR),
• the voltage between the star point of the transformer and earth (voltage drop across the NGR),
• the condition of the NGR,
• line-to-line and line-to-earth voltages.
This quick-start guide does not replace the operating manual of the device.
