    Instruction book Electrical cable size Important The voltage on the vacuum pump terminals must not deviate more than 10% of the nominal voltage. It is however highly recommended to keep the voltage drop over the supply cables at nominal current below 5% of the nominal voltage (IEC 60204-1). •...
