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 1000 pF, “Y” 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:
Fuses for both Line and Neutral are provided in the power supply.
NOTE: For use in permanently installed equipment, remove Fuse F2 and replace with a jumper wire.
WARNING! RISK OF FIRE!
A blown internal fuse is an indication of catastrophic failure of circuit
component(s). Refer to fuse marking on the power supply for rating. Repair must be performed by
SLPE authorized personnel.
WARNING! SHOCK HAZARD!
Dangerous voltages are present on some components, printed wiring
traces and heatsinks.
