Figure 1-1 Means of heat dissipation
Fan design
● The fan must be positioned to produce an optimum heat dissipation. A clearance of 10 mm
must be maintained in front of the fan.
● The inlet and outlet slots must remain free for the open-circuit ventilation.
● Air filters must be provided to maintain the permitted environmental conditions.
NOTICE
Damage to the operating components caused by temperatures that are too high or too low
Contaminated air filters impair the desired heat dissipation. For handling the air filters, pay
attention to:
● Proper handling
● Regular replacement
● Correct disposal
