To avoid shock hazard, lock out incoming 
power to power cables when completing 
connections. Failure to do so may result in 
severe burns, injury or death. 
 
 
It is the responsibility of the OEM to ensure that 
suitable line and load cables are used to satisfy 
the requirements of the equipment and meet 
local electrical codes. 
 
 
1) Use appropriate cable lugs to attach suitable line cables to the 
line cable terminal (upper power terminal) of the heatsink 
assembly. The terminal is predrilled with a mounting hole with a 
diameter of 10.3 mm (0.406 in.). The holes are suitable for M10 
(3/8 in.) hardware. Refer to Figure 4.8 for the terminal location. 
Torque the fastening hardware to the specifications shown in 
Table 4.D. 
2) Use cable lugs to attach suitable load cables to the load cable
terminal (lower power terminal) of the heatsink assembly. Refer 
to Figure 4.8 for the terminal location. Torque the fastening 
hardware to the specifications shown in Table 4.D. 
3) Refer to Chapters 6 and 7 for a typical wiring diagram to
determine the required connections. Appendix B includes a 
typical schematic for a complete soft starter unit.
