WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or
death, or damage to the equipment can occur. If you are not a qualified
electrical professional, do not do installation, commissioning or
maintenance work.
1.
Stop the drive and do the steps in section
before you start the work.
2.
Open the door of the DC/DC converter cubicle and remove the shrouding. See
Connecting the DC power cables and the disconnector status monitoring
cable (page
30).
3.
Run the control cables inside the cubicle. Ground the cable shields 360° at the
cable entry. See subsection
at the cabinet entry (page
4.
Run the cables to the control connections terminal X350 and connect. See
connection diagram (page
frame. The terminal block for the user connections is on a swing-out frame. The
frame needs to be opened for maintenance work.
Grounding the outer shields of the control cables 360° at the cabinet entry
Ground the outer shields of all control cables 360° with the EMI conductive cushions
at the cabinet entry. The grounding principle is the same for top and bottom entry
cables. The illustrations show the bottom entry. The actual design details can vary.
1.
If necessary, remove the shrouding in front of the cable entry.
2.
Put the cables in sequence from the smallest to the largest. This will help to achieve
a good contact with the cushions.
3.
Loosen the tightening bolts of the EMI conductive cushions and pull them apart.
4.
Cut holes in the grommets and put the cables through the grommets.
5.
Peel the insulation from the part of the cable that will be in contact with the EMI
conductive cushion.
6.
Put the cables between the cushions and attach them with cable ties for strain
relief.
7.
Move the cushions back together.
8.
Tighten the bolts to make sure that the EMI conductive cushions press tightly
around the peeled part of the cables.
