Safety and Installation Instructions
Installation Instruction
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 according to:
Mechanical Data.
The units should be connected to a secondary circuit.
Check for hazardous voltages before altering any connec-
tions.
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 F1A for
24 IMP 3 and 24 IXP 3 types and F0.5A for 48 IMP 3 and
48 IXP 3 types..
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.
Standards and approvals
The units have been evaluated for:
Building in
Operational insulation input to output
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 (IMP 3) or
4000 V (IXP 3).
Protection Degree
The protection degree of the DC-DC converters is IP 40.
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.
