1. Remove the 2 x M4 x 16 screws using a pozi drive screwdriver.
2. Remove the bucket suppressor terminal cover.
Shielded cable should be used for bucket suppressor connections. For 
UL applications the cable should comply with UL1063 in accordance 
with UL508a.
For applications where the external suppressor resistance is chosen to 
be less than the recommended value for reasons of economy, it is 
essential that the resistance is not less than the minimum resistance 
shown in Table 4-19. However selecting a resistance less than the 
recommended value requires a more complex installation. The power 
rating of the resistor can be selected by the user according to the 
dissipation required for the application, up to a maximum of the values 
specified in Table 4-19.
