For the cable types, see Selecting and routing the energy storage cables on page 62 .
WARNING! Repeat the steps described in section Electrical safety
precautions on page 66 . The complete safety instructions are given in
Safety instructions for ACS880 multidrive cabinets and modules
(3AUA0000102301 [English]). 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.

2. Open the door of the DC/DC converter cubicle and remove the shrouding (if any).
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. Connect the conductors to appropriate terminals. See the connection diagram of the
cabinet installer. For the tightening torques, see Tightening torques on page 154 .
7. Twist the cable screens into bundles and connect them to the protective grounding
busbar (PE) of the cabinet.
8. Refit any shrouding removed earlier and close the cubicle doors.
