4.5.  Mount the disconnect switch to the structure using the hardware indicated by the 

Operating Mechanism drawing (see 

Table 1

 for torque spec). 

4.6.  The Mounting Positions and Proper Blade Openings are shown in

 Figure 10

. 

 

 

Figure 10:  Proper Mounting Positions 

4.6.1.  Conventional blade open positions are shown i

Figure 10

. The EV-2H switch 

will be shipped with one of these blade open angles unless another angle is 

specified. Slight changes to the blade fully open angles are easily made in the 

field. Simply adjust the open position stop bolt on the blade carrier assembly 

shown i

Figure  11

, and then readjust the stop located at the bottom of the 

rotating insulator to match the blade angle.
