Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 con-
nector. Pin no. 24, the protective earth pin present on all
LKP AC-DC converters is leading, ensuring that it makes
contact with the female connector first.

Installation Instructions
The KP series AC-DC converters are components, in-
tended exclusively for inclusion within other equipment by
an industrial assembly operation or by professional install-
ers. Installation must strictly follow the national safety regu-
lations in compliance with the enclosure, mounting,
creepage, clearance, casualty, markings and segregation
requirements of the end-use application.
Connection to the system shall be made via the female con-
nector H15 (see:
Accessories). Other installation methods
may not meet the safety requirements.
The AC-DC converters are provided with pin no. 24 ( ),
which is reliably connected with their case. For safety rea-
sons it is essential to connect this pin with the protective
earth of the supply system.
An input fuse is built-in in the connection from pins no. 30
and 32 (P~) of the unit. Since this fuse is designed to pro-
tect the unit in case of an overcurrent and does not neces-
sarily cover all customer needs, an external fuse suitable
for the application and in compliance with the local require-
ments might be necessary in the wiring to one or both input
potentials, pins nos. 26 and 28 and/or nos. 30 and 32.
Important: Whenever the inhibit function is not in use, pin
no. 18 (i) should be connected to pin no. 14 (Vo1–) to en-
able the output(s).
Do not open the modules, or guarantee will be invali-
dated.
Due to high current values, all LKP units provide two inter-
nally parallel connected contacts for certain paths (pins 4/6,
8/10, 26/28 and 30/32, respectively). It is recommended to
connect load and supply to both female connector pins of
each path in order to keep the voltage drop across the con-
nector pins to an absolute minimum and to not over-
stress the connector contacts if currents are higher than
approx. 8 A. The connector contacts are rated 8 A over the
whole temperature range.
Make sure there is sufficient air flow available for convec-
tion cooling. This should be verified by measuring the case
temperature when the unit is installed and operated in the
end-use application. The maximum specified case tem-
perature
TC max shall not be exceeded. See also: Thermal
Considerations.
If the end-product is to be UL certified, the temperature of
the main isolation transformer should be evaluated as part
of the end-product investigation.
Check for hazardous voltages before altering any connec-
tions.
The output provides a hazardous energy level according to
IEC/EN 60950.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also:
Safety
of operator accessible output circuit.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids is to be prevented, since the power supplies
are not hermetically sealed.
