Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 con-
nector. The protective earth pins (pins 12 and 14) present
on all PC series converters are leading pins, ensuring that
they make contact with the female connector first.

Installation Instructions
The PC 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, creep-
age, clearance, casualty, markings and segregation requi-
rements of the end-use application.
Important: Since the PC series AC-DC converters do
not provide electrical input to output isolation, their out-
put circuit is a Hazardous Voltage Primary Circuit which
must not be user accessible.
DC-DC converters with accessible output circuits, pow-
ered by a PC series AC-DC converter must provide dou-
ble or reinforced insulation, based on the mains input
voltage of the PC series AC-DC converter. Refer to:
Safety of operator accessible output circuit of the H, K,
M, P, Q and S series data to determine safe installation if
such DC-DC converters are powered by a PC series
unit.
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 pins 12 and 14
( ), which are reliably connected to the case. For safety
reasons it is essential to connect at least one of these pins
to the protective earth of the supply system.
The P
and N
inputs (pins 8 and 10) are both internally
fused. These fuses are designed to protect the unit in case
of overcurrent and may not be able to satisfy all customer
requirements. External fuses in the wiring to one or both
input pins may therefore be necessary to ensure compli-
ance with local requirements.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition.
Important: Do not open the modules, or guarantee will
be invalidated.
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 user’s application. The maximum specified case tem-
perature
TC max shall not be exceeded. See also: Thermal
Considerations.
Caution: Check for hazardous voltages before and after
altering any connections. Hazardous voltages may be
present at the output terminals for 1 minute even after
the mains input voltage has been disconnected from the
unit.
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.
Standards and approvals
All PC series 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. LGA ap-
proval to IEC/EN 60950 standards pending. The units for:
Building in
Basic insulation between input and case based on their
maximum rated input voltage
Operational insulation between input and output (Opera-
tional insulation according to the standards includes the
case where only rectification and voltage/current regula-
tion by diodes and transistors is provided, as is the case
for PC series AC-DC converters. If the input circuit is a
primary circuit, the output is a primary circuit, too.)
Use in a pollution degree 2 environment.
The AC-DC converters are subject to manufacturing sur-
veillance in accordance with the above mentioned UL,
CSA, EN and with ISO 9001 standards.
Protection Degree
Condition: Female connector fitted to the unit.
IP 40: All units.
