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.
