1.0    Required Tools: 

1.1. 

Installation of this trip unit does not 

require tools but since minor repairs and 
adjustments are generally made at the same 
time as the trip unit is upgraded, it is 
recommended that a full set of basic hand 
tools be available.  When upgrading the trip 
unit on breakers above 2000A, an included 
jumper must be added to the existing wiring 
harness.  If this modification is required, it is 
recommended that the pin extraction tool 
listed in table 1 be available.  This is because 
it is not possible to remove and reposition the 
jumper without the tool if it inserted 
incorrectly in error.  The table lists several 
commercial sources of this tool.  It can also 
be obtained through 

Satin American.
