Removal of Components
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before
servicing. Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
It is assumed that all work can be done inside the starter panel. No wiring should
have to be done in the control panel. However, access to the control panel to verify
wiring origins may be necessary.
Removal of Motor Protection Module (A1 or MPM), and Circuit Breakers CB11 and
CB15
1. Before removing the MPM, mark wires landing on V1, V2, D1 (wire #125B) & D2
(wire #127A). These wires will be re-landed on CH531 components.
2. Remove wires from CTs that land on C1-C6. The existing CTs can be removed
and discarded. New CTs will be used with CH531 components. The new CTs are
not included in this KIT. They must be ordered separately. See Table 1 in Appendix
C for details.
3. Remove wires (#130 and #131) for CB11 (Compressor Motor Current Overload)
from F1 and F2. Remove wires (#132 and #133) for CB15 (Distribution Fault) from
E3 and E4. These two circuit breakers, CB11 and CB15, in the starter panel door
will have to be removed as they will no longer be required, the functions will be
performed by the CH531 components.
See Appendix B for wiring details.
A sheet of black vinyl is included so that "patches" may be cut to fit and be placed
over the holes in the starter door where these breakers were mounted.
The Starter Circuit Fault Indicator (CB13) can remain as wired.
Remove the remaining wires from the MPM and remove the module.
When complete the bottom bracket should be left attached to the starter backpanel.
The new component sub-panel sent in this kit will attach to the tapped holes on the
flanges of the existing bottom bracket.
