Warning
The max. supply voltage U

+30%
(62V=) must not be exceeded at any
time
(not even for short
intervals)!
Danger of damage!

The power supply
connection has no protection against
reverse polarity.
If the polarity of the connection is
wrong, the device will be destroyed!

Battery connecting line <2m. For conductor lengths from 2 to 10m more powerful. Use an
additional capacity for conductor lengths superior to 10m!
Auxiliary voltage connection
Mains potential-free auxiliary dc voltage
24V= ±10%/2A
The auxiliary voltage
- is galvanically connected with the
logic voltage
- has internal regenerating fuses
- has an EMC filter
External fuse only for line protection

Switch-on current 2A
Nominal current
0.8A
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.
