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.
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 F2A for
24 IMS 7 types and F1A for 48 IMS 7 types.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids has to be prevented, since the power sup-
plies are not hermetically sealed.
Standards and approvals
All DC-DC converters are UL recognized according 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
The DC-DC converters are subject to manufacturing sur-
veillance in accordance with the above mentioned UL,
CSA, EN and ISO 9001 standards.
Protection Degree
The protection degree of the DC-DC converters is IP 30.
