Step 5

This step contains cable routing and installation procedures . 

Make sure that cables move freely in their cable housings before 

installation . When attaching cables to swivel fittings, ensure that 

both ends of the cable are connected to push swivel fittings or 

both ends of the cable are connected to pull swivel fittings (refer to 

Figure 10

) . For example, a cable connected to the Drive Lever Pull 

Swivel Fitting on Breaker A must connect to the Driven Lever Pull 

Swivel Fitting on Breaker B . 

ATTENTION

FIGURE 9 SHOWS THE TYPICAL CABLE ROUTING FOR TYPE 32 INTERLOCK
