Connection
• Use only commercial cables designed for the indicated voltage and current
values!
• With flexible cables: make sure that all cable strands are secured in the terminal.
• Suitable conductor terminal sleeves (ferrules) may be used.
• Ensure proper polarity at output terminals!
Grounding
• Do not operate the unit without PE connection!
Units of protection class I that are connected to the mains must not be operated
without adequate earthing of the housing.
• The housing is connected to the earth terminal PE
.
• The secondary side is not earthed; if necessary, the „0V“- terminal can be
earthed
Internal fuse
The unit is protected against short circuit and overload with a fuse (F1) on the
primary side. The fuse must only be replaced by a fuse of the same type and the
same current rating!
Reverse feeding
The specified output voltages (continuous / short-time) must not be exceeded by
reverse feeding through a connected drive system (braking operation)
Maintenance
The unit does not need regular maintenance. If there are visible dust deposits clean
the unit with low pressure compressed air.
Recycling
The unit contains elements which are suitable for recycling, and components which
need special disposal. You are therefore requested to make sure that the unit will
be recycled by the end of its service life.
Operational notes
Output current
Continuous load must not exceed the nominal output current I
OUTn
.
The maximum permissible short time output current (t = 0.5 s) applies to seldom
occuring overload situations (duty rating < 1%). The lower the overload current the
longer the allowable time, as listed below. These approximate values hold true for a
basic load of 50% I
OUTn
.

When overload appears often or periodically, the effective value of the output current
must not exceed the nominal output current I

.
Exceeding the specified limit values may cause the mains fuse to blow.
