OVERVOLTAGE PROTECTION: Only output #1 is monitored for an overvoltage condition. The trip-point
for a 5 volt output is 5.6 to 6.8 volts. In some applications where an overvoltage condition could result in a
hazard as defined in applicable safety standards, redundant or additional overvoltage protection may be required.
Consult factory for details.
CAUTION: When performing Dielectric Strength Tests, catastrophic failure of the unit may result if a
Dielectric Strength test voltage greater than 1800 V ac is applied between primary and secondary circuits. The
components providing isolation from primary to secondary cannot be tested while installed in the power supply
without overstressing basic (primary to ground) insulation. All isolating components are individually 100 %
tested at 4800 V ac prior to installation.
ISOLATION: The creepage distance between primary and ground is 4 mm minimum; between primary and
secondary circuits is 8 mm minimum. Secondary to ground creepage is not defined or controlled. The output
common is bypassed to ground using a 0.01 µF 1kV capacitor. The required creepage and clearance distances
from primary circuits to ground and secondary circuits must be maintained after installation to preserve the
intended safety.
TEMPERATURES: The maximum operating temperatures of certain safety components, as defined in the
applicable safety standards, must not be exceeded after installation to preserve the intended safety. The output
power, ambient air temperature and the availability, amount, direction and/or restriction of airflow influence the
temperatures of these components.
OVERCURRENT PROTECTION: The internal fuse is located in the phase lead only. EN 60601-1 requires
that both supply leads (phase and neutral) be protected against overcurrent. Complete overcurrent protection
must be provided in the host equipment. Fuse ratings must not exceed that specified for the internal fuse, must
meet the requirements of EN 60601-1 and be acceptable for the country in which the host equipment is to be
installed.
WARNING! RISK OF FIRE! A blown internal fuse is an indication of catastrophic failure of circuit
component(s). Repair must be performed by SL Power Electronics Corp. authorized personnel. Refer to fuse
marking on the supply for rating.
WARNING! SHOCK HAZARD! Dangerous voltages are present on some components, printed wiring traces
and heatsinks.
