The electrical power cable must be suitably sized to avoid voltage drops.
Cable drums must not be used. The size of the power cable wires must
be based on operating current and length of the power line to prevent
excessive voltage drops (tab.3).

Before connecting the cement mixer to the power supply, check that
all the safety devices are in place and working properly, that the power
supply cable is in good condition and that the plugs and sockets (of
the waterproof type) are not wet. Check that the metal grilles protecting
the electric motor are not clogged, to prevent overheating of the motor
itself.
Connect the power supply cable to the electric panel plug. Start the
