Safety Consideration
For safety-agency approval of the system in which the power module is used, the power
module must be installed in compliance with the spacing and separation requirements of the
end-use safety agency standard, i.e., UL1950, CSA C22.2 No. 950-95, and EN60950. The
ALT series input-to-output isolation is an basic insulation. The DC/DC power module should
be installed in end-use equipment, in compliance with the requirements of the ultimate
application, and is intended to be supplied by an isolated secondary circuit. When the supply
to the DC/DC power module meets all the requirements for SELV(<60Vdc), the output is
considered to remain within SELV limits (level 3). If connected to a 60Vdc power system,
double or reinforced insulation must be provided in the power supply that isolates the input
from any hazardous voltages, including the ac mains. One input pin and one output pin are
to be grounded or both the input and output pins are to be kept floating.
Single fault testing
in the power supply must be performed in combination with the DC/DC power module to
demonstrate that the output meets the requirement for SELV. The input pins of the module
are not operator accessible.
Note: Do not ground either of the input pins of the module, without grounding one of
the output pins. This may allow a non-SELV voltage to appear between the output pin
and ground.
