Signals In Separate Cables; Signals That Can Be Run In The Same Cable; Relay Cable Type; Control Panel To Drive Cable - ABB ACS880 Electrical Planning Instructions

24 Electrical planning guidelines
A double-shielded cable (a) is the best alternative for low-voltage digital signals, but
single-shielded (b) twisted pair cable is also acceptable.

￭

Signals in separate cables

Run analog and digital signals in separate, shielded cables. Do not mix 24 V DC and
115/230 V AC signals in the same cable.
￭

Signals that can be run in the same cable

If their voltage does not exceed 48 V, relay-controlled signals can be run in the same cables
as digital input signals. The relay-controlled signals should be run as twisted pairs.
￭

Relay cable type

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 with male RJ-45 connector, cable type Cat 5e or better. The maximum permitted
length of the cable is 100 m (328 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 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.
This figure illustrates the cable routing guidelines with an example drive.
