Connector Pin Allocation
The connector pin allocation table defines the electrical
nector. Pin no. 24, the protective earth pin present on all LK
AC-DC converters is leading, ensuring that it makes con-
tact with the female connector first.

Installation Instructions
The K series AC-DC converters are components, intended
exclusively for inclusion within other equipment by an in-
dustrial assembly operation or by professional installers. In-
stallation must strictly follow the national safety regulations
in compliance with the enclosure, mounting, creepage,
clearance, casualty, markings and segregation require-
ments of the end-use application.
Connection to the system shall be made via the female con-
nector H15/H15 S2 (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 (S–/Vo1–) to
enable the output(s).
Do not open the modules, or guarantee will be invali-
dated.
