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!

Positive Switching Regulator (Rugged)
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.
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.
