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 LS
AC-DC converters is leading, ensuring that it makes con-
tact with the female connector first.

Installation Instructions
The S 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 (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.
Due to high current values, all LS 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 overstress
the connector contacts if currents are higher than
approximately 8 A. The connector contacts are rated 8 A
over the whole temperature range.
Make sure that there is sufficient air flow available for con-
vection 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.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also:

of operator accessible output circuit.

Standards and Approvals
All AC-DC converters correspond to class I equipment.
They are UL recognized according to UL 1950, UL recog-
nized for Canada to CAN/CSA C22.2 No. 950-95 and LGA
approved to IEC/EN 60950 standards.
The units have been evaluated for:
Building in
Basic insulation between input and case, based on 250 V
AC and 400 V DC
Double or reinforced insulation between input and output,
based on 250 V AC and 400 V DC
Basic insulation between output and case based on
200 V DC and AC
Operational insulation between output and output
The use in a pollution degree 2 environment
Connecting the input to a primary or secondary circuit
which is subject to a maximum transient rating of 2500 V
(overvoltage category III based on a 110 V primary cir-
cuit, overvoltage category II based on a 230 V primary
circuit).
The AC-DC converters are subject to manufacturing sur-
veillance in accordance with the above mentioned UL,
CSA, EN and with ISO 9001 standards.
