5. Install the adaptor harnesses for voltage sensing
connection:
a. Disconnect the generator set harness at P2 on
the back of the RDC2 controller. See Figure 6.
b. Connect the adaptor harness to P2 on the
RDC2 controller. See Figure 6 and Figure 8.
c. Connect the other end of the adaptor harness
to the generator set harness.
d. Repeat for the second generator set.
6. The adaptor harness connected in step 5 contains
a voltage sensing lead (V9). Connect one 14-20
AWG lead to this lead and route it with the AC
output leads from the generator to the APM
location. Repeat for the second generator set.
Note: Do not operate the generators in parallel without
the adaptor harness in place.
harness contains protective devices that prevent
controller damage when connecting to a large
inductive load (such as another generator).
Note: Electrical connections to the APM will be made
later.

module (APM).
7. To remove the enclosure's front panel, support the
panel while removing the screws. Pull the bottom
of the panel out and down until the top clears the
enclosure. Remove the inner panel to access the
APM components.
8. See the dimension drawings in Section 8 for
recommended cable entrance areas. Cover the
components inside the enclosure. Then punch or
drill cable entry openings in the APM enclosure.
9. Use a vacuum cleaner to remove debris from the
enclosure.
