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. The adaptor
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.
1.2 Install the automatic paralleling
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.
Note: Do not use compressed air to clean the
inside of the enclosure. Cleaning with
compressed air can cause debris to lodge
inside the components and damage the
equipment.
10. Mount the enclosure to a wall or other rigid vertical
supporting structure using the mounting holes
provided in the enclosure. See Figure 32 for
mounting hole spacing. Use shims to plumb the
enclosure.
Note: The enclosure mounting holes are equipped
with gaskets to seal out moisture. Use
washers with the mounting screws to
prevent damage to the gaskets.
