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
. Connect the input grounding wire
⑪
to the input grounding hole on NEMA 1 main frame
⑦
. Connect the three line wires to L1/L2/L3 terminals.
Tie the input magnetic core
⑩
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 output grounding wire
⑬
to the output grounding hole on NEMA 1 main frame
⑦
.
Connect the motor wires to U/V/W terminals. 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:
1. Run input c
able (including three line wires and one input
grounding wire) through conduit fitting. Connect the
input grounding wire
⑪
to the input grounding hole on
NEMA 1 main frame. Connect three line wires to
L1/L2/L3 terminals.
2. Run the output cable (including three motor wires and
one output grounding wire) through conduit fitting and
EMC grounding clamp
⑭
. Connect the output grounding
wire
⑬
to the output grounding hole on NEMA 1 main
frame
⑦
. Connect the motor wires to U/V/W terminals.
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.
