Table 11 lists lug kits for use with the SIKOSTART 3RW34 con-
trollers. Each kit provides a method of adapting a controller for
use with aluminum or copper power wiring. One kit contains
lugs for either the line or load side of the controller. Two kits are
required to add lugs to both line and load terminals.
Figure 30 shows a lug in position for mounting to the terminal.
The table 11 Lug Hardware Torque column indicates the torque
required for the screw that secures the lug to the controller ter-
minal. The Wire Size Range column lists the wire sizes that the
lug can accommodate. Table 3 in this manual indicates the
torque required for the set screw that secures the wire in the
lug.
Complete installation instructions are furnished with each
lug kit.
Note:
