Standards and Approvals
The DC-DC converters correspond to class I equipment. All
types are LGA approved to IEC/EN 60950 standards.
The units have been evaluated for:
Building in,
Basic insulation between input and case/output, based
on 250 V AC and 400 V DC,
Basic insulation between output and case, based on
250 V AC and 400 V DC,
The use in a pollution degree 2 environment,
Connecting the input to a circuit which is subject to a
maximum transient rating of 2500 V.
The DC-DC converters are subject to manufacturing sur-
veillance in accordance with EN 60950 and ISO 9001
standards.
Protection Degree
The protection degree of the DC-DC converters is IP 40,
exept in the vicinity of the terminals, where it depends on
the installation.
Isolation
The electric strength test is performed as factory test in ac-
cordance with IEC/EN 60950 and UL 1950 and should not
be repeated in the field. Melcher will not honour any guar-
antee claims resulting from electric strength field tests.

Safety and Installation Instructions
Installation Instructions
Our DC-DC converters are components, intended exclu-
sively for inclusion within other equipment by an industrial
assembly operation or by professional installers. Installation
must strictly follow the national safety regulations in compli-
ance with the enclosure, mounting, creepage, clearance,
casualty, markings and segregation requirements of the
end-use application. See also:
Technical Information: In-
stallation and Application.
Connection to the system shall be made via the
6.3
× 0.8 mm faston contacts at the cover side of the unit
according to
Mechanical Data.
The DC-DC converters are provided with an earth pin (
),
which is reliably connected with their case. For safety rea-
sons it is essential to connect this pin with the protective
earth of the supply system if required in:
Safety of operator
accessible output circuit.
An input fuse is built-in in the connection from the Vi+ termi-
nal of the unit. Since this fuse is designed to protect the unit
in case of an overcurrent and does not necessarily cover all
customer needs, an external fuse suitable for the applica-
tion and in compliance with the local requirements should
be installed in the wiring to one or both input pins (Vi+ and/
or Vi–).
Important: Whenever the inhibit function is not in use,
pin i should be connected to pin Vo1– to enable the out-
put. Do not open the modules, or guarantee will be invali-
dated.
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 end-use application. The maximum specified case tem-
perature
TC max shall not not be exceeded. See also: Ther-
mal Considerations.
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.
