Step 4
Power wiring for EMI version drive:
1. Run input cable (including three line wires and one
input grounding wire) through conduit fitting and input
magnetic core
⑩
, then connect to L1/L2/L3 terminals,
leave the input grounding wire
⑪
unconnected. Tie the
input magnetic core to the input wires with a cable tie
(See A).
2. Run the output cable (including three motor wires and
one output grounding wire) through conduit fitting
and EMC grounding clamp
⑭
. Run the three motor
wires without the output grounding wire through the
output magnetic core
⑫
. Connect the motor wires to
U/V/W terminals. Leave the output grounding wire
⑬
unconnected. Tie output magnetic core to the output
wires with a cable tie. Use the EMC grounding clamp
⑭
and two screws
⑮
to fix output cable shielding layer
(See B).
Power wiring for non-EMI version drive:
Run input cable (including three line wires and one input
grounding wire) through conduit fitting. Connect to L1/L2/L3
terminals. Leave the input grounding wire
⑪
unconnected
3. Run the output cable (including three motor wires and
one output grounding wire) through conduit fitting and
EMC grounding clamp
⑭
. Connect the motor wires to
U/V/W terminals. Leave the output grounding wire
⑬
unconnected. Use the EMC grounding clamp
⑭
and two
screws
⑮
to fix output cable shielding layer.
Control wiring:
1. Run control wires (RJ45, ethernet, I/O, STO, relay, etc.)
through control wire conduit fittings
⑨
and connect to
corresponding terminals or connectors.
