Safety and Installation Instructions

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

approx. 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.

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:

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.
