INFORMATION
Lubricant on page 138
The milling machine was varnished with a one component lacquer. This fact must be taken into
account when selecting your cooling lubricant.
Optimum Maschinen Germany GmbH does not accept any liability for subsequent damages
due to unsuitable cooling lubricants.
The flashpoint of the emulsion must be higher than 140°C.
When using non-water-miscible cooling lubricants (oil content > 15%) with a flashpoint, ignitable
aerosol air mixtures might develop. There is a potential danger of explosion.

CAUTION!
Must only be worked on by a qualified electrician or person working under the
instructions and supervision of a qualified electrician.
ATTENTION!
Ensure that all 3 phases (L1, L2, L3) and the ground wire are connected correctly.
The neutral conductor (N) of its power supply is not connected.
Correct direction of rotation, observe phase sequence!

If necessary, two phase connectors at the three phase current switch (MH50G) or at the con-
nection in the control cabinet must be exchanged. The guarantee will become null and void if
the machine is connected incorrectly.
CAUTION!
Arrange the machine's connection cable in such a way that it will not cause a tripping
hazard.
Please verify if the type of current, voltage and protection fuse correspond to the values speci-
fied. A protective earth ground wire connection must be available.
Main Fuse 16A.

WARNING!
Danger to life caused by high leakage currents for an interrupted protective conductor.
The drive components conduct a high leakage current via the protective conductor.
Touching conductive parts when the protective conductor is interrupted can result in
death or serious injury.
Observe the following notes on the connection for machines with frequency converters.
