A - to detect AC fault currents and pulsating DC fault currents (provided the DC current

reaches zero at least once every half cycle).
B - to detect AC fault currents, pulsating DC fault currents and smooth DC residual currents.

Type AC should never be used in converters.
Type A can only be used for single-phase converters.
Type B must be used for 3-phase converters.
When using an external EMC filter, to avoid false error shutdowns, a time delay of at least 50
ms is required. The leakage current can exceed the threshold trigger value for an error shut-
down if the phases are not switched on at the same time.

Cleaning and lubrication


Remove the anti-corrosive agents on the milling machine which had been applied for trans-
portation and storage. Therefore, we recommend you to use paraffin.

To clean, do not use any solvents, nitro-cellulose thinner or other cleaning agents that could
damage the paint of the milling machine. Observe the information and notes of the cleaning
agent manufacturer.

Oil all blank machine parts using an acid-free lubricating oil.

Lubricate the milling machine according to the lubricating plan.


Check if all spindles are running smoothly. The spindle nuts are re-adjustable.
INFORMATION
The milling machine is lacquered with a
when selecting your cooling lubricant.
The company Optimum Maschinen Germany GmbH does not assume any guarantee for sub-
sequent 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.
