Electrical connection

5.1 Electric connection of machine to low voltage network
Caution!
All work on the electrical equipment of this special sewing machine
may only be carried out by qualified electricians or other appropriately
trained persons.
It is unconditionally necessary to study the instructions for the motor
(drive) supplied by the producer!
The control DAC classic or DAC basic is connected to a grounded
alternating low voltage network with the rated voltage in scope 180V -
260V, 50/60Hz.For the Efka DA321G drive the supply voltage is 230 V
± 10%, 50/60 Hz.
Caution!
The mains voltage must agree with the rated voltage specified on the
model-identification plate.
The connection may be realized only by means of a multipole socket
with a protective contact. A fixed connection is inadmissible.
All instructions for the drive connection can be found in the Operating
manual for the DAC basic/classic drives or for the Efka drive.
Caution! Risk of electric current injury!
The drives may be operated only with a safety conductor connected to
the functional protective system in accordance with the regulations and
rules to avoid personal injuries by electric current or fire.
The drive operation will become dangerous if the safety conductor
inside or outside the drive is disrupted. The protection must not be
disrupted with e. g. an extension cord without the protective conductor.
