IMPORTANT
•
These instructions apply only to Enwatch boards P/N EK-44750C. Enwatch CSANI P/N
EK-44750CSANI must be returned to a Rockwell Automation repair center for all
board replacements and repairs.
•
All Enwatch boards (EK-44750C and EK-44750CSANI) built before July 2005 were
powered by a 12V DC power supply. All boards shipped after July 2005 operate using
a 24V DC power supply.
•
It is important to use the correct power supply when exchanging Enwatch boards.
Using the incorrect power supply can cause damage to the Enwatch board.
•
Always replace both the board and the power supply using the components
supplied in the kit, catalog number EK-44750C-RK24V series B.
Note:
Repairs and retrofits should be made only by authorized Rockwell service
personnel.
IMPORTANT
The kit is designed to replace the EK-44750C Enwatch board. To avoid mismatching the
power supply and Enwatch board, you must replace the mounting base plate (with 24V
DC power supply) and board at the same time. Do not replace only the board.
