Armored cable/shielded power cable
Six conductor (3 phases and 3 ground) type MC continuous corrugated aluminum armor cable with
symmetrical grounds is available from the following suppliers (trade names in parentheses):
– Anixter Wire & Cable (Philsheath).
– BICC General Corp (Philsheath).
– Rockbestos Co. (Gardex).
– Oaknite (CLX).
Shielded power cables are available from Belden, LAPPKABEL (ÖLFLEX) and Pirelli.
Selecting the control cables
Shielding
All control cables must be shielded.
Use a double-shielded twisted pair cable (figure A below) for analog signals. This type of cable is also
recommended for the pulse encoder signals. Employ one individually shielded pair for each signal. Do not use
common return for different analog signals.
A double-shielded twisted pair cable (figure A below) is the best alternative for low-voltage digital signals but a
single-shielded twisted pair cable (figure B below) is also acceptable.
The pairs should be twisted as close to the terminals as possible.
Signals in separate cables
Run analog and digital signals in separate, shielded cables. Never mix 24 V
DC
and 115/230 V
AC
signals in the
same cable.
Signals allowed to be run in the same cable
Relay-controlled signals, providing their voltage does not exceed 48 V, can be run in the same cables as digital
input signals. The relay-controlled signals should be run as twisted pairs too.
Relay cable type
The cable type with braided metallic screen (for example ÖLFLEX by LAPPKABEL, Germany) has been tested
and approved by ABB.
Control Panel cable length and type
In remote use, the cable connecting the control panel to the drive must not exceed three meters (10 ft).
Cable type: Shielded CAT 5e or better Ethernet patch cable with RJ-45 ends.
A: Double-shielded twisted pair cable.
B: Single-shielded twisted multi pair cable
