SECTION 7
THREE PHASE FLEXPAK PLUS MODIFICATION KIT
INSTRUCTION MANUALS
7.0 General - A number of optional features in the
form of Modification Kits are offered with the three
phase, FlexPak Plus controller. Each of these Kits exĆ
tends the control of the unit and tailors its operation to
specific application needs.
This Section describes the procedures that must be folĆ
lowed to install the Kits. Refer to Table 7.A for an informaĆ
tional listing.
DANGER
INSTALLATION OF MODIFICATION KITS IS TO
BE DONE ONLY AFTER AĆC LINE VOLTAGE IS
DISCONNECTED AND LOCKED OUT AT THE
MAIN DISCONNECT SWITCH. DO NOT INSTALL
KITS WHEN POWER IS APPLIED TO THE
FLEXPAK PLUS CONTROLLER. SERIOUS PERĆ
SONAL INJURY AND EQUIPMENT DAMAGE
COULD RESULT.
CAUTION: Installation of the Modification Kits
should be performed only by qualified electrical
maintenance personnel familiar with the design
and operation of this equipment. Damage could reĆ
sult thru unfamiliarity.
Many of the Modification Kits are designed to make
electrical connection with the Regulator Module by
means of pinĆtype connectors. These slide up through
matching holes in the Modules that form part of the Kit.
(Refer to Figure 7.1.)
PINS MUST BE PARALLEL
Figure 7.1 - Pin Alignment
A common installation problem is caused by bent,
broken or incorrectly placed pins. Since improper opĆ
eration results, care must be taken. Exact alignment is
critical. Visually check that only one pin extends to the
top of each slot once the connection is made.
Many of the Modification Kits require the removal of one
or more jumpers from the Regulator Module. In such
cases, carefully clip the leads on both sides of each
jumper and discard it. Use a sharp pair of dykes (diagoĆ
nal cutters) to assure a quick, clean cut. Do not twist the
tool, since damage may result.
In cases where the Kit is secured by a mounting screw,
be sure to tighten it firmly but do not overtighten. ExĆ
cessive force can strip the threads.
