Connection procedure of the energy storage cables
For the cable types, see Selecting and routing the energy storage cables on page 38 .
WARNING! Repeat the steps described in section Electrical safety
precautions on page 42 . The complete safety instructions are given in
Safety instructions for ACS880 multidrive cabinets and modules
(3AUA0000102301 [English]). Ignoring the instructions can cause
physical injury or death, or damage to the equipment.
WARNING! With aluminum cables, apply grease to stripped 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.

2. Open the door of the DC/DC converter cubicle and remove the shrouding.
3. Lead the cables into the cubicle.
4. Ground the cable shield 360 degrees at the cable entry. See the instructions by the
cabinet installer. An example grounding arrangement is shown below.
5. Cut the cables to suitable length. Strip the cables and conductors, and install the cable
lugs at the end of the conductors.
6. Twist the cable screens into bundles and connect them to the protective grounding
busbar (PE) of the cabinet.

cabinet installer. For the tightening torques and busbars, see Tightening torques on
page 111 and chapter Dimensions .
8. Refit any shrouding removed earlier and close the cubicle doors.
