6.1 Electromagnetic compatibility (EMC)
Description If connecting cables (e.g. field buses, etc.) are routed to the control PC from 
outside, only shielded cables with an adequate degree of shielding may be 
used. The cable shield must be connected with maximum surface area to the 
PE rail in the cabinet using shield terminals (screw-type, no clamps).
6.2 Installation conditions
Dimensions The robot controller can be installed in a 19" rack or as a standalone device. 
The specifications in the “Technical data” chapter  (>>> 4 "Technical data" 
Page 21) must be observed. If the robot controller is to be installed in a 19" 
rack, the depth must be at least 700 mm.The robot controller is designed for 
use in the horizontal position. The robot controller can optionally be operated 
in the vertical position.
Both sides of the robot controller must always be accessible to the cooling air. 
Clearance of 70 mm on each side.
The robot controller corresponds to EMC class A, Group 1, in accor-
dance with EN 55011 and is intended for use in an industrial setting. 
Assuring the electromagnetic compatibility in other environments 
may be difficult due to conducted and radiated disturbances that are liable to 
occur.
If the robot controller is to be installed in a 19" rack, it must be fas-
tened in the rack by appropriate means (preferably angle plates) 
along the entire side edge in order to prevent distortion of the hous-
ing.
