Safety and Installation Instructions
Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the Positronic
connector. Pin no. 45 (protective earth) is a leading pin,
ensuring that it makes contact with the female connector
first.
Installation Instructions
These converters are components, intended exclusively for
installation within other equipment by an industrial
assembly process or by a professionally, competent
person. Installation must strictly follow the national safety
regulations in respect of the enclosure, mounting, creepage
distances, clearance, casualty markings, and segregation
requirements of the end-use application.
Connection to the system shall be made via the mating
female connector (see fig. 16). Other installation methods

Pin numbers shown are for the female backplane connector
A = very long pins, B = long pins, C = short pins, D = very short pins.
Pin 45 of the female connector is leading, ensuring that chassis ground makes contact first.

may not meet the safety requirements. Check for hazardous
voltage, before altering any connections.
The converters are provided with a leading pin no. 45, which
is reliably connected to the case. For safety reasons it is
essential to connect this pin to the protective earth of the
supply system.
The input –DCIN or ACL (pin no. 47) is internally fused; see
Input Fuse and Protection. This fuse is designed to break an
overcurrent in case of a malfunction of the converter and is
not customer-accessible.
External fuses in the wiring to one or both input lines (pin 47
and/or pin 46) may be necessary to ensure compliance with
local requirements. A built-in second fuse in the neutral line
(pin 47) is available as option F for CPA500 models.
A second fuse in the wiring to the neutral line or option F may
be needed if:
Pin
• Local requirements demand an individual fuse in each
• Neutral and earth impedance is high or undefined
• Phase and neutral of the mains are not defined or cannot

Caution:
Installation must strictly follow the national safety regulations.
Models with option F: Caution! Double-pole/neutral fusing.
Do not open the converters, or the warranty will be
invalidated!
Important: If the inhibit function is not used, pin 39 (i) should
be left open-circuit to enable the outputs. Enable Pin 27 (EN#)
should be connected to pin 22 (RTN) to enable the outputs.
