15.3 Power supply
Dangerous electrical voltage! Connection of the machine as well as electrical
inspections, maintenance and repair may only be carried out by qualified personnel
or under the supervision and supervision of a qualified electrician!
Heavy current machines must always be connected to 3 phases and an earthing.
Check the correct running direction of the lathe immediately after making the
electrical connection! If necessary, replace two of the three phases (L1/L2 or L1/L3)!
The machine is operated with high voltage current (400 V, 3~, 50 Hz). The use of 16 A fuses is
recommended.
15.3.1 Establishing the power connection
To connect the machine to the electrical mains, proceed as follows:
Check that the supply voltage and current frequency correspond to the specifications on
the machine nameplate.
Use a suitable device to check that the zero connection and earthing are working
properly.
The power supply circuit must be equipped with overvoltage protection (RCD with
maximum residual current of 30 mA).
For the required cross-section of the supply cables, please refer to the current carrying
capacity table. (Make sure that the cables are in good condition and suitable for power
transmission. Undersized cables reduce the power transmission and heat up
considerably.)
Connect the supply cables to the corresponding terminals in the input box (L1, L2, L3, N,
РЕ) - see following figure. If there is a СЕЕ plug, the connection to the mains is made by
an appropriately supplied СЕЕ coupling (L1, L2, L3, N, РЕ).
