Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 connector.
Pin no. 26, the protective earth pin, is a leading pin, ensuring
that it makes contact with the female connector first.

The Vi– input (pin 32) is internally fused. This fuse is designed
to protect 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 (no. 30 and/or no. 32) may therefore be
necessary to ensure compliance with local requirements.
Important:
• If the inhibit function is not used, pin 28 (i) must be connected
with pin 32 (Vi–) to enable the output(s).
• Do not open the converters, or warranty will be invalidated.
• Long input, output and auxiliary lines, or lines with inductors,
filters or coupling/decoupling networks may cause instabilities.
See Input Stability with Long Supply Lines.
Due to high output currents, the Q1001/1101 models offer two
internally parallel-connected contacts for both, the positive and
the negative output path (pins 4/6 and pins 8/10). It is
recommended to connect the load to both female connector
pins of each path in order to keep the voltage drop across the
connector pins to a minimum.
Make sure that there is sufficient air flow available for
convection cooling. This should be verified by measuring the
case temperature when the converter is installed and operated
in the end user application. The maximum specified case
temperature T_{C max} shall not be exceeded. See also Thermal
Considerations.
Ensure that a converter failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also Safety of
Operator-Accessible Output Circuits.
Cleaning Agents
In order to avoid possible damage, any penetration of cleaning
fluids must be prevented, since the power supplies are not
hermetically sealed.

Installation Instructions
The Q Series converters are components, intended
exclusively for inclusion within other equipment by an
industrial assembly operation or by professional installers.
Installation must strictly follow the national safety regulations
in compliance to enclosure, mounting, creepage, clearance,
casualty, markings and segregation requirements of the end-
use application.
Connection to the system shall be made via the female
connector H15 (see Accessories). Other installation methods
may not meet the safety requirements.
The Q Series converters are provided with pin 26 ( ), which is
reliably connected to the case. For safety reasons it is
essential to connect this pin to protective earth; see Safety of
Operator-Accessible Output Circuits.
Protection Degree
Condition: Female connector fitted to the converters.
IP 30: All models, except those with option P (potentiometer).
IP 20: All models fitted with option P.
Standards and Approvals
The Q Series converters correspond to class I equipment.
They are safety agency approved to UL/CSA 60950-1 and
IEC/EN 60950-1 2^nd Edition.
The converters have been evaluated for:
• Class I equipment
• Building in
• Basic insulation between input and case and double or
reinforced insulation between input and output, based on
their maximum rated input voltage
• Basic insulation between Out-OK and case, and double or
reinforced insulation between Out-OK and input, and
between Out-OK and output, based on their maximum rated
input voltage
• Functional insulation between outputs and output to case
• Use in a pollution degree 2 environment
