2.  Cooling 
As shown in the above gure, keep sufcient clearances around the servo drive to ensure 
cooling by cooling fans or natural convection. Install cooling fans above the servo drive 
to avoid excessive temperature rise and maintain even temperature inside the control 
cabinet. 
3.  Installation side by side
When installing multiple servo drives side by side, keep at least 10 mm between two servo 
drives (if installation space is limited, such clearance between servo drives can be ignored) 
and at least 50 mm above and below each servo drive.
4.  Grounding 
The grounding terminal must be properly grounded. Failure to comply may cause electric 
shock or malfunction due to interference.
