Safety and Installation Instructions
Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 or H15S4
connector. Pin 24 (protective earth) is a leading pin, which
provides electrical contact first. The regulators should only be
wired via the female connector H15 (according to DIN 41612)
to ensure requested safety!

Installation Instruction
Installation of the regulators must strictly follow the national
safety regulations in compliance with the enclosure, mounting,
creepage, clearance, casualty, markings, and segregation
requirements of the end-use application.
The input and the output circuit are not separated. The
negative path is internally interconnected.
The regulators should be connected to a secondary circuit.
Make sure that a regulator failure (e.g. by an internal short-
circuit) does not result in a hazardous condition.
Do not open the regulator!
Standards and Approvals
All switching regulators are class-I equipments and have been
approved according to UL 60950, CSA 60950, and IEC/EN
60950.
The regulators have been evaluated for:
The switching regulators are subject to manufacturing
surveillance in accordance with the above mentioned
standards and with ISO 9001:2000.
Cleaning Agents
In order to avoid possible damage, any penetration of cleaning
fluids must be prevented, since the regulators are not
hermetically sealed.

Protection Degree
The protection degree is IP 30 (IP 20, if equipped with
option P). It applies only, if the regulator is plugged-in or
the matching female connector is properly attached.
Isolation and Protective Earth

These tests are performed in the factory as routine test
in accordance with EN 50116 and IEC/EN 60950. The
electric strength test should not be repeated by the
customer. Power-One will not honor any warranty
claims resulting from electric strength tests.
