Connecting The Signal Lines - ABB EasyLine Series Instructions For Installation Start-Up And Operation

Connecting the Signal Lines

Requisite Material
Connecting the Signal Lines
NOTES
Follow local regulations on installing and connecting electrical wiring.
Lay the signal lines separately from the power supply lines.
Lay analog and digital signal lines separately from each other.
Mark the cables or mating plugs in such a way that they can be clearly
assigned to the corresponding I/O modules.

Select conductive material which is appropriate for the length of the
lines and the predictable current load.

Notes concerning the cable cross-section for connection of the
I/O modules:

The max. capacity of terminals for stranded wire and solid wire is
2
1 mm (17 AWG).

The stranded wire can be tinned on the tip or twisted to simplify
the assembly.

When using wire end ferrules, the total cross-section may not be
more than 1 mm
not be more than 0.5 mm
Weidmüller & Co. must be used for crimping the ferrules.

Max. length of the RS485 leads 1200 m (max. transmission rate
19200 bit/s). Cable type: 3-core twisted-pair cable, cable cross-
2
section 0.25 mm

Max. length of the RS232 leads 15 m.

The mating plugs (socket housing) for the plug-in terminal strips on
the I/O modules are supplied.
1 Only for the wall-mount housing (EL3040 model): Pass the cables
through the screwed cable glands (see page 82) and strip to a length
of approx. 18 cm.
M20 and M32: Remove the plugs from the insert; leave the ring in the
screwed cable glands for sealing and strain relief.
M25: Remove the plugs from the screwed cable glands. If required,
slit open the insert with drill holes from the accessories pack and
press over the cable; seal any open drill holes with dowel pins from
the accessories pack.
2 Connect the lines to the mating plugs as shown in the connection
diagrams of the I/O modules:
Analog output module (see page 84)
Digital I/O module (see page 85)
3 Attach the mating plug to the plug-in terminal strips on the I/O-
modules.
