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.
