SAFETY DECLARATION: SL Power Electronics Corp. declares under our sole responsibility that all
models listed above are in conformity with the applicable requirements of EN 60950-1 following the
provisions of the Low Voltage Directive 73/23/EEC. All models are Certified to be in compliance with the
applicable requirements of UL 60950, CSA 22.2 No. 60950, and EN 60950-1 for Pollution Degree 2
environment and Class I TN-S power systems. The outputs of the supplies meet the requirements for SELV
and are not an energy hazard.
CAUTION: The ground connection must be bonded to Protective Earth in the end application in order to meet the required
creepage distances from primary to secondary. Do not use this connection for the primary system earthing terminal.
Creepage and clearance distances from primary circuits to ground and secondary circuits, as defined in the applicable safety
standards, must be maintained after installation to preserve the intended safety.
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.
WARNING! RISK OF FIRE!
A blown fuse is an indication of catastrophic failure of circuit component(s). Repair must be performed by SL Power
Electronics Corp. authorized personnel.
