7.3 DRY-OUT / WARM-UP PROCEDURE
Before applying power to the converter for the first time, or after an extended period of no power applied to
the converter, it is necessary to go through a heat/dry cycle.
This is dependent on many factors, including the following:
• Where the converter was manufactured;
• When the converter was manufactured;
• The converter’s final installation location;
• The environmental conditions at the time of final installation and commissioning.
The dry-out process must be implemented by one or more of the following:
• All doors and panels closed;
• Operating the internal heater systems (e.g. anti-condensation heaters);
• Applying an external heat source;
The duration of the dry-out period is dependent on the initial condition of the equipment and the following
time durations are recommended:
Initial condition of equipment
Recommended dry-out period
Commissioning of equipment in humid conditions
Commissioning of equipment in dry conditions
Re-starting of equipment following a period of isolation in excess of 48 hours
