Safety and Installation Instructions
Installation Instructions
Installation of the DC-DC converters must strictly follow the
national safety regulations in compliance with the enclo-
sure, mounting, creepage, clearance, casualty, markings
and segregation requirements of the end-use application.
Connection to the system shall be made via a printed circuit
board with hole diameters of 1.4 mm
±0.1 mm for the pins.
The units should be connected to a secondary circuit.
Check for hazardous voltages before altering any connec-
tions.
Do not open the module.
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.
Input Fuse
To prevent excessive current flowing through the input sup-
ply line in case of a short-circuit across the converter input
an external fuse should be installed in a non earthed input
supply line. We recommend a fast acting fuse F4.0A for
20 IMX 15 types, F2.0 A for 40 IMX 15 types and a fuse
F1.0A for 110 IMY 15 types.
Standards and approvals
All DC-DC converters are pending to be UL recognized ac-
cording to UL 1950, UL recognized for Canada to CAN/
CSA C22.2 No. 950-95 and LGA approved to IEC/EN
60950 standards.
The units have been evaluated for:
Building in
Supplementary insulation input to output, based on their
maximum input voltage (IMX 15 types)
Reinforced insulation input to output, based on their
maximum input voltage (IMY 15 types)
The use in a pollution degree 2 environment
Connecting the input to a secondary circuit which is sub-
ject to a maximum transient rating of 1500 V (IMX 15
types)
Connecting the input to a primary circuit which is subject
to a maximum transient rating of 2500 V (IMY 15 types)
After approvals the DC-DC converters are subject to manu-
facturing surveillance in accordance with the above men-
tioned UL, CSA, EN and with ISO 9001 standards.

Protection Degree
The protection degree of the DC-DC converters is IP 40.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids should be prevented, since the power sup-
plies are not hermetically sealed.
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.
