Installation and Connection
3.5 Control board xxB6Bxx-xxx (CAN)
3.5.1 X2A Control terminal strip
The control connections are „safety separated circuits“ according to PELV requi-
rements.
• Conductor cross-section AWG 20-16 X2A
rigidly or exibly 0.5…1.5 mm²
Wire-end ferrule without plastic case 0.5…1 mm²
Wire-end ferrule with plastic case 0.5 mm²
• Strip length 8 mm
• Use shielded / drilled cables
• Lay shield on one side of the inverter onto earth potential
