￭
Relay cable
The cable type with braided metallic shield (for example ÖLFLEX by LAPPKABEL,
Germany) has been tested and approved by ABB.
￭
Control panel to drive cable
Use EIA-485, Cat 5e (or better) cable with male RJ-45 connectors. The maximum
length of the cable is 100 m (328 ft).
￭
PC tool cable
Connect the Drive Composer PC tool to the drive through the USB port of the
control panel. Use a USB Type A (PC) - Type Mini-B (control panel) cable. The
maximum length of the cable is 3 m (9.8 ft).
Routing the cables
￭
General guidelines – IEC
•
Route the motor cable away from other cables. Motor cables of several drives
can be run in parallel installed next to each other.
•
Install the motor cable, input power cable and control cables on separate trays.
•
Avoid long parallel runs of motor cables with other cables.
•
Where control cables must cross power cables, make sure that they are
arranged at an angle as near to 90 degrees as possible.
•
Do not run extra cables through the drive.
•
Make sure that the cable trays have good electrical bonding to each other and
to the grounding electrodes. Aluminum tray systems can be used to improve
local equalizing of potential.
The following figure illustrates the cable routing guidelines with an example drive.
Note: When motor cable is symmetrical and shielded and it has short parallel runs
with other cables (< 1.5 m / 5 ft), distances between the motor cable and other
cables can be reduced by half.
