Inrush
The initial inrush current is internally limited by
an NTC resistor 10 times the rated current
(about 2ms). The response is maintained
between off and on again when a waiting time
of 120sek is maintained. The NTC resistance is
in the cooling power of the equipment fan.
For faster turn-off, the inrush current to
increase to 30 times the value (1ms). The
switching contacts of the power contactors
must be designed for these values.
Precharge
By using the assembly precharge the charge
current to 2 times rated current is limited. The
contactor K1 is switched time-delay.
Auxiliary voltage connection:
Mains potential-free 24V= +/- 10% / 2A auxiliary direct current.
The auxiliary voltage has a: galvanic connection to the logic voltage,
galvanic safety dc decoupling to all internal supply voltages of the device,
an internal self-healing fuse,
an EMC filter,
an external fuse only for line protection.

GND connection must be earted!
Note:
In addition to the internal supply current (0.8A) the sum of the output
currents (DOUT) must be provided by the mains module 24V.
Note:
If the auxiliary voltage is inferior to 20V - even in case of short-time
voltage drop-outs - the internal mains module is switched off. Any data of the RAM are
deleted!
The speed and the position command values are set to zero and any calibrated data are
deleted.
The LED signal for the state “OK” is dark.
