Electrical Safety Statement
Installation Of The Valley Electric Irrigation Machine - European Union Only
Valmont Industries Inc. does not install a differential (ground fault) circuit breaker in the control panel of the
Valley electric irrigation machine because the standards of protection vary according to country of destination.
The distributor must provide and install a differential (ground fault) circuit breaker that meets the standards of
the country where the Valley irrigation machine is installed.
In the European Union, differential circuit breaker protection is fixed at a maximum of 24 volts.
Good grounding of the Valley irrigation machine is required.
• If resistance to ground is lower than 80 ohms, a differential (ground fault) circuit breaker of 300 mA will meet
requirements.
• If resistance to ground is between 80 and 800 ohms, a differential (ground fault) circuit breaker of 30 mA will
meet requirements.
The power supply installation and inspection of equipment protection components or machines are the
responsibility of the installer. Valmont Industries Inc. Is not responsible for the failure of equipment protection
components or machine not of their manufacture.
Valley pivot irrigation machines receiving power from a generator must have a cable connected from the
irrigation machine structure to a ground rod and another cable from the irrigation machine structure to the
ground terminal on generator in order for the differential (ground fault) circuit breaker to work.
• The resistance between the irrigation machine and the generator must be substantially below 80 ohms.
