Safety and Installation Instructions
Installation Instruction
Installation of the switching regulators 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.
Check for hazardous voltages before altering any connec-
tions. Connections can be made using fast-on or soldering
technique.
The input and the output circuit are not separated. i.e. the
negative path is internally interconnected!

Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids is to be prevented, since the power sup-
plies are not hermetically sealed.
The units should be connected to a secondary circuit.
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.
