Safety and Installation Instructions
Installation Instruction
Standards and Approvals
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.
All switching regulators are UL recognized according to UL
1950, UL 1012 and EN 60950, 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/out-
put to case,
Check for hazardous voltages before altering any connec-
tions. Connections can be made using fast-on or soldering
technique.
• The use in an overvoltage category II environment,
• The use in a pollution degree 2 environment.
The input and the output circuit are not separated, i.e. the
negative path is internally interconnected!
The switching regulators are subject to manufacturing sur-
veillance in accordance with the above mentioned UL and
CSA and with ISO 9001 standards.
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.
Isolation
Electric strength test voltage between input interconnected
with output against case: 750 VDC, 1 s.
Cleaning Agents
This test is performed in the factory as routine test in
accordance with EN50116, IEC/EN 60950 and UL 1950
and should not be repeated in the field. Power-One will not
honour any guarantee claims resulting from electric
strength field tests.
In order to avoid possible damage, any penetration of
cleaning fluids is to be prevented, since the power supplies
are not hermetically sealed.
Protection Degree
The protection degree is IP 20.
