ELECTRIC EQUIPMENT
The electric power supply of the machine is realized through a 3 phase power
supply line with a voltage and frequency being specified in the "Packing list or
on the data plate, placed of the electric box door.
The electrical equipment secures a normal operation of the machine with input
power supply fluctuations of ±10 % and frequency fluctuations of ±2% of the
rated values.
The electrical power supply is realized by power cable 4x6 mm
2
when four-wire
mains is used and 5x6 mm 2 in case of five-wire mains. The cable passes through
the electric inlet, placed on the electric box. It is connected to main breaker's Q1
terminals L1, L2, L3 and, depending on the mains type, to the terminal PE or N,
situated close to the main breaker Q1.
After the connection check whether the movements directions of machine corre-
spond to those set by means of the control levers and change the phase sequence
on two of terminals L1, L2 or L3 when it is necessary.
The degree of protection of the machine is IP44 according EN 60529.
The electric circuit diagram and the wiring diagram are presented on Fig.16 and
Fig.17.
