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 1.5 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 F8.0A for
20 IMX 35 types, F4.8 A for 40 IMX 35 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
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
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.
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. Power-One will not honour any
guarantee claims resulting from electric strength field tests.

Protection Degree
The protection degree of the DC-DC converters is IP 30 (not
for option Z).
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.
