4.7. Control Terminal Wiring

All analog signal cables should be suitably shielded. Twisted pair cables are recommended.
 Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other

Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable.
 Maximum control terminal tightening torque is 0.5Nm
4.8. Connection Diagram
4.8.1. Power Terminal Designations
Incoming Mains Power Supply
For 1 Phase Supply, connect to
L1/L and L2/N terminals.
For 3 Phase Supply, connect to
L1, L2 & L3 terminals.
Phase sequence is not
important. Motor Connections
Connect the motor to the U, V & W
terminals.
The motor earth must be connected
to the drive
Optional Brake Resistor & DC Bus
Connections
Where a Brake resistor is used, it
must be connected to the BR+ and
DC- terminals
Protective Earth / Ground
connection.
The drive must be Earthed /
Grounded
