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!
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:

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 40, IP 20 with option P and for
PSR 52.
Isolation
Electric strength test voltage between input intercon-
nected with output and case: 750 V DC, 1 s.
This test is performed as factory test in accordance with
IEC/EN 60950 and UL 1950 and should not be repeated in
the field. Melcher will not honour any guarantee claims re-
sulting from electric strength field tests.
