Delta DPS-400K - UPS Fan System

2-14
Ultron DPS Series
2.7 Fans
There are fans on the top of the UPS to assist ventilation. Please see Figure 2-14 for fans
location. The system senses the critical loads connected and decides the fan speed. Fans
will run at the highest speed only when an over-current condition occurs (battery over
temperature is excluded).
