3.3 Control terminal strip X2A
The control terminal strip is designed as a double, plug-in terminal strip with push in cage
connection. It contains 32 poles. The following instructions must be observed at connection:
ATTENTION
Prevent eMC malfunctions
• Use shielded / drilled cables
• Lay shield on one side of the inverter onto earth potential
• Lay control and power cable separately (about 10...20 cm apart);
Lay crossings in a right angle (in case it cannot be prevented)

Assembly of connecting wires without wire-end ferrules
•
Press pusher by hand. Insert connecting wires into the respective hole, that no single wires can be seen
from the outside or bend outward. A first resistance must be overcome when inserting. Release the pusher.
•
Check that the connecting wire is fixed and can not be pulled-out. It is important to ensure that the con
-
necting wire and not the insulation is clamped. The connecting wire can also be inserted without press-
ing the pusher in case of cross-sections upto 1.00 mm².

ATTENTION
A safe clamping can not be guaranteed when using shorter wire-end
ferrules.
KEB generally recommends the use of wire-end ferrules in industrial environments.
