Wiring Methods Section 2-4
Note The current capacity of thick cable is 8 A, so up to 16 A can be supplied to the
network by supplying communications power in two directions from the power
supply through thick cables.
The current capacity of thin cable is limited to 3 A. Up to 6 A can be supplied
to the network when communications power is supplied in two directions from
the power supply through thin cables.
If a thin cable is connected in one direction and a thick cable is connected in
the other, the maximum current is 3 A + 8 A = 11 A total.

Communications
Cables
Use the following procedure to prepare and connect the communications
cables to the connectors.
1,2,3... 1. Strip about 30 mm of the cable sheathing, being careful not to damage the
woven shield just below the sheathing. Do not remove more than about
30 mm; removing too much of the covering can result in short circuits or
allow noise into the Network.
2. Carefully peel back the woven shield. There is a bare shield wire under the
woven shield as well as the signal lines and power lines. (The shield wire
will be loose on the outside of the other lines, but it is stiffer than the woven
shield and easy to identify by touch.)
3. Cut away the exposed woven shield, remove the aluminum tape from the
signal and power lines, and strip the sheath from the signal and power lines
to the proper length for the crimp terminal connectors. Twist together the
stranded wires of each signal and power lines.
Ambient humidity 30% to 90% (with no condensation)
Surge current capacity 10% max.
