The equipment covered by this standard commences at the point of connection of the supply to the electrical equipment of the machine. This part is applicable to the electrical equipment or parts of the electrical equipment that operate with nominal supply voltages not exceeding 1000 V for alternating current and not exceeding 1500 V for direct current, and with nominal frequencies not xeceeding 200 Hz. For higher voltages or frequencies, special requirements may be needed.
