The entire component must be cooled. The maximum temperature of the electrolytic capacitor C6, C51 and C52 must keep lower than
"Electrolytic capacitor allowable Max temperature" in the above table. As reference, set wind velocity at 0.7m/s (ZWS50-150BAF),
1.4m/s (ZWS300BAF-12, 15), 0.7m/s or 1.4m/s (ZWS300BAF-24, 36, 48).
For ZWS300BAF, maximum output power is different from convection cooling and forced air cooling. Please confirm specifications, and be
careful.
