Renewal Kits for PowerFlex
755TS Products with
Corrosive Gas Protection
(XT)
All PowerFlex 755TS product renewal kits with corrosive gas protection (XT)
meet the corrosive atmosphere specification as defined by Rockwell
Automation. For details on the corrosive atmosphere specification, see the
PowerFlex 755TS Products with TotalFORCE® Control Technical Data,
publication
Protective Packaging for Renewal Kits with XT
Renewal kits with XT are shipped in packaging that is designed to protect
products while stored at industrial sites that can be exposed to corrosive gas.
Do not remove the packaging or protective film from a renewal kit while it is in
storage.
Protective Covers on Kits with XT
Some renewal kits with XT use protective covers to seal terminal bocks, circuit
board connectors, and wire harness connectors. The covers protect against
contamination and corrosion in corrosive gas environments. For the product
to meet the corrosive atmosphere rating, protective covers must remain
installed in or on unused connectors during storage and operation. See
for examples of protective covers.
For kits with protective covers:
•
Do
not
remove a protective cover from an unused connection or a kit in
storage.
•
Remove a protective cover when a connection must be made at
installation only.
‘XT’ appears in the kit catalog number to identify a kit that contains protective
covers. For example, the catalog number for the main control circuit board
with XT is SK-RT-MCB1-PF755-
XT
.
