External consumers (sockets)
To the two sockets at the back, two 230V consumers can be connected. The left socket seen from
behind is switched with relay 1 and is usually intended for the spindle motor. The right socket is
switched with relay 2 and can be used either for a vacuum cleaner, a coolant pump, or other
aggregates.
The maximum current consumption of each individual consumer must not exceed
8A.
The sum of
the current consumption must not exceed
13.5A
(16A minus the maximum own consumption).
Please note that the maximum current consumption may be higher than the nominal power of the
device would suggest. The maximum current consumption, which also considers start-up and
reactive currents, can be found on the type of plate or in the documents of the manufacturers.
Exceeding the maximum current leads to the triggering of the fuses located inside the housing.
