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. 26, the protective earth pin present on all
BQ...GQ DC-DC converters is leading, ensuring that it
makes contact with the female connector first.

Protection Degree
Condition: Female connector fitted to the unit.
IP 30: All units, except those with option P (potentiometer).
IP 20: All units fitted with option P (includes potentiometer).
Installation Instructions
The Q series DC-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, creep-age,
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 DC-DC converters are provided with pin no. 26 (
),
which is reliably connected with the case. For safety rea-
sons it is essential to connect this pin to the protective earth
of the supply system if required in the table:
Safety concept
leading to an SELV output circuit.
The Vi input (pin no. 32) is internally fused. This fuse is de-
signed 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 (no. 30 and/or
no. 32) may therefore be necessary to ensure compliance
with local requirements.
Important: Whenever the inhibit function is not in use,
pin no. 28 (i) must be connected to pin no. 32 (Vi–) to en-
able the output(s). Do not open the modules, or guaran-
tee will be invalidated.
Long input, output and auxiliary lines or lines with
inductors, filters or coupling/decoupling networks may
cause instabilities. See also:
Technical Information:
Sense Lines.
Due to high output currents, the BQ...GQ 1001 units pro-
vide two internally parallel connected contacts for both the
positive and the negative output path (pins 4/6 and pins
8/10 respectively). 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 an absolute
minimum.
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.
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.
