Installation Instruction
Note The ARM-IDM Retro-fit Kit will only function on those CM52 break-
ers which utilize the Indicating Diagnostic Module (IDM) . This kit cannot
be applied to the first generation CM52 using the Voltage Regulator Device
(VRD) as the breaker wiring is different from that of current production .
Installation of this kit should take approximately 2 .5 hours . Please refer to
your supplied wiring diagram as certain component add-ons can change
the configuration of the relay module . For help, please contact EATON,
Greenwood, SC (PH- 864-942-6211) .
For ease of wiring to INCOM or any connections to be made outside of the
network housing, it is suggested that you use the Bulkhead Entry Box, style
number NFX0012G01 .
StEP 1
Following all safety guidelines, open the network breaker and place
it in the drawn out and disconnected position .
Warning
ensure that the breaker is de-energized prior to proceeding.
StEP 2
Remove the front cover of the CM52 breaker using the 10 mm
socket supplied with the lever-out crank . Loosen the four cover bolts;
they should be captive to the front cover .
Note: Pull the manual closing handle completely forward to facilitate the
removal of the front cover .
StEP 3
Remove the existing IDM by opening the cover on the right center
of the IDM and removing the screw . Pull the IDM straight out from
the breaker to avoid bending any of the contact pins .
StEP 4
Remove the mounting plate which supports the IDM . There are four
Phillips head screws that hold this plate in position .
