Control circuit
2.1.5 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 pole. The following instructions must be observed at connection:
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)
2.1.5.1 Assembly of the PUSH-IN terminal strip
Assembly of connecting wires with wire-end ferrules
according to DIN46228/4

• 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 connecting wire and not the insulation is clamped. The connecting wire can also be inserted
without pressing the pusher in case of cross-sections upto 1.00 mm².

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.
