Safety and Installation Instructions
Connector Pin Allocation
Pin no. 26 (protective earth) is leading, ensuring that it makes
contact with the female connector first.

Installation Instructions
The H Series converters are components, intended exclusively
for inclusion within other equipment by professional installers.
Installation 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.
Connection to the system shall be made via the female
connector H11. Other installation methods may not meet the
safety requirements.
The converters are provided with pin no. 26 (
reliably connected with the case. For safety reasons, it is
essential to connect this pin with the protective earth of the
supply system.
A non-accessible input fuse is connected in the line to pin 32
(L ). Since this fuse is designed to protect the converter in
case of an overcurrent and does not necessarily cover all
customer needs, an external fuse suitable for the application
and in compliance with the local requirements may be
necessary in the wiring to one or both input pins (no. 29 and/or
no. 32), particularily if the phase or neutral line cannot be
assigned to the corresponding terminals.

Important: If the inhibit function is not in use, pin 2 (i) should be
connected with pin 23 (Vo–) to enable the output(s).
Caution: Do not open the converters, or warranty will be
invalidated.
Not connected, if option neither option D or V is fitted.

Standards and Approvals
The converters correspond to class I equipment and have
been approved according to the standards IEC/EN 60950-1
and UL/CSA 60950-1.
The converters have been evaluated for:
The converters are subject to manufacturing surveillance in
accordance with the above mentioned standards and with ISO
9001:2000.
Isolation
The electric strength test is performed in the factory as routine
test in accordance with EN 50116 and IEC/EN 60950, and
should not be repeated in the field. Power-One will not honor
any warranty claims resulting from electric strength field tests.

Thermal Considerations.
Cleaning Agents
In order to avoid possible damage, any penetration
of liquids (e.g., cleaning fluids) has to be prevented,
since the power supplies are not hermetically
sealed.
Note: All boards are coated with a protection lacquer.
