3. Verify that the PSS model is the one that you ordered, and ensure that the voltage
meets your specific requirements.
3.2 Mounting and Wiring the PSS
For optimum heat dissipation, the power supply should be installed with the heatsink
fins in the vertical direction.
3.2.1 Wiring Guidelines
1. Use flexible wires with the proper cross-section to handle the unit current. Color
coding is recommended.
2. After wiring is completed, carefully inspect all conditions in order to ensure
tightness.
3.2.2 AC Power Supplies
The PSS power supplies do not include inrush current control. Therefore, they
should be connected to an isolating/floating transformer.
