Power cable connection procedure
WARNING! Obey the safety instructions in chapter Safety instructions . If you
ignore them, injury or death, or damage to the equipment can occur.
WARNING! Apply grease to stripped aluminum conductors before attaching them
to non-coated aluminum cable lugs. Obey the grease manufacturer.’s instructions.
Aluminum-aluminum contact can cause oxidation in the contact surfaces
For the standard drive module configuration:
•
See the step-by-step installation drawings in ACS880-04F quick installation guide
(3AXD50000044913 [multilingual])
•
Connect the full-size output cable connection terminals to the drive module.
For optional input power cable connection terminals and ground busbar assembly
(+H370):
•
Install the metallic shroud with ground bar as shown in section Attaching the metallic
shroud (standard and with ground bar [H370]) on page 54
•
Connect the full-size input power cable connection terminals in a similar way as the
motor cable connection terminals, see
ACS880-04F quick installation guide
(3AXD50000044913 [multilingual]).
For drive modules without full-size output cable connection terminals (0H371) and
IP20 shrouds (0B051), Connect the power cables directly to the drive module
input and output terminals with cable lugs or by busbars. Protect the power cable terminals
and electrical parts against contact and ground the drive module correctly.
Cabinet installation:
1. Run the motor cables from the motor to the cabinet. Ground the cable shields 360° at
the lead-through plate.
2. Twist the cable shields of the motor cables into bundles and connect them and any
separate ground conductors or cables to the ground terminal of the drive module or to
the cabinet ground bar.
3. Connect the phase conductors of the motor cables to terminals T1/U2, T2/V2 and
T3/W2 of the drive module. For the tightening torques, see page 127 .
4. Drive modules with D150: Run the power cables from the brake resistor to the
cabinet. Ground the cable shield (if present) 360° at the lead-through plate. Connect
the conductors to the R+ and R- terminals. For the tightening torques, see page
127 .
6 External brake resistor (optional, see page 165 )
7 Common mode filter (optional, see page 59 )
8 du/dt filter (optional, see page 171 )
9 The drive module frame must be connected to the cabinet frame. See section Arranging the
grounding inside the cabinet on page 40 .
Note:
If there is a symmetrically constructed grounding conductor in the motor cable in addition to the conductive
shield, connect the grounding conductor to the grounding terminal at the drive and motor ends.
Do not use an asymmetrically constructed motor cable. Connecting its fourth conductor at the motor end
increases bearing currents and causes extra wear.
