Removal is accomplished by pulling the green jumper from the connector on 
the ISM . Once removed, the jumper should be placed in the clear vinyl pocket 
containing the unit test data for future use if desired (Figure 10) .

 recommends feeding all PX3 models with a disconnect, 

circuit breaker, molded case switch or fused disconnect .

If a breaker or molded case switch is used for connecting the phase 
conductors, Current Technology

®

 recommends using circuit breakers 

in the range of 60 to 100 amps.

 

W A R N I N G !   Prior to proceeding, ensure the SPD unit does not 

have voltage applied to its input terminals.

PX3 models equipped with a filter system (“-F” suffix), and have a neutral 
connection, come with a green jumper wire that loops out of the 3-pin 
connector on the ISM and connects a filter neutral to ground . In certain 
medical applications, or circuits which employ GFCI protection, this Neutral to 
Ground filter connection should be removed .
