Installation and Commissioning

3 Connecting Signals

3.1 Signal classes

Power – supplies external motors and brakes.
Control signals – digital operating and data signals (digital I/O, safety stops, etc.).
Measuring signals – analog measuring and control signals (resolver and analog I/O).
Data communication signals – Gateway (Field bus) connection, computer link.
Different rules apply to the different classes when selecting and laying cable. Signals
from different classes must not be mixed.

3.2 Selecting cables

All cables laid in the controller must be capable of withstanding 70
following rules apply to the cables of certain signal classes:
Power signals -Shielded cable with an area of at least 0.75 mm
any local standards and regulations concerning insulation and area must always be
complied with.
Control signals – Shielded cable.
Measuring signals – Shielded cable with twisted pair conductors.
Data communication signals – Shielded cable with twisted pair conductors. A spe-
cific cable should be used for Gateway (Field bus) connections.
CAN bus with DeviceNet for distributing I/O units;
Thin cable according to DeviceNet specification release 1.2, must be used, e.g. ABB
article no. 3HAB 8277-1. The cable is screened and has four conductors, two for elec-
tronic supply and two for signal transmission.
Note that a separate cable for supply of I/O load is required.
Allen-Bradley Remote I/O;
Cables according to Allen-Bradley specification, e.g. "Blue hose", should be used for
connections between DSQC 350 and the Allen-Bradley PLC bus.
Interbus-S:
Cables according to Phönix specification, e.g. "Green type", should be used for con-
nections between the DSQC 351 and external Interbus-S bus.
