Note When VCTF cable is being used, cover the end of the cable sheathing with
electrical tape or heat-shrink tubing as shown in the following diagram.
2. Crimp pin terminals on the stripped ends of the communications cable and
secure the terminal and wire with electrical tape or heat-shrink tubing.
Note a) We recommend the following pin terminals.
b) We recommend the following crimper:
Weidmüller PZ1.5 Crimper (part number 900599)
c) The Weidmüller 901851 Sleeve cannot be used.
3. Insert the pin terminals into the CompoBus/S terminal block on the front of
the CPM2C-S and tighten the locking screw.
The maximum lengths of the trunk line, branch lines, and total transmission
line length depend on the communications mode and the kind of transmission
line (flat cable or VCTF cable) being used. The maximum lengths are further
restricted if flat cable is being used with more than 16 Slaves.
