Safety and Installation Instructions
Installation Instruction
Installation of the switching regulators must strictly follow
the national safety regulations in compliance with the en-
closure, mounting, creepage, clearance, casualty, mark-
ings and segregation requirements of the end-use applica-
tion.
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!
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.
Protection Degree
The protection degree is IP 20.
Standards and Approvals
All switching regulators are UL recognized according to UL
1950, UL 1012 and EN 60950 and UL recognized for
Canada to CAN/CSA C22.2 No. 234-M90.
The units have been evaluated for:
• Building in,
• Operational insulation from input to output and input/
• The use in an overvoltage category II environment,
• The use in a pollution degree 2 environment.
