Installing and Wiring the Throat Connection Kit
After the inverter and transformer assemblies have been secured, install the
throat connection kit (see Figure 3-8 on page 3–13 through Figure 3-14 on page
3–16).
To install the throat connection kit:
1. Install the three-phase and ground bus bars provided in the throat
connection kit to the inverter and transformer assemblies using the provided
M10 fastening hardware and cover plates. See Figure 3-12 on page 3–15
and the photographs in Figure 3-8 on page 3–13. Bolt size and torque
specifications are in Table A-7 on page A–6. Items required for these bus bar
connections are listed and their correct installation order is illustrated in
Figure 3-12.
2. Connect the 10-pin and 16-pin control cables connector (P15 and P16) from
the inverter assembly to the transformer assembly. See Figure 3-12 and the
photographs in Figure 3-8. Make sure the connector clamp is secure as
shown in Figure 3-9 on page 3–13.
3. Make the TB13 and TB14 connections:
a) Remove the clear plastic cover over the TB13 and TB14 distribution
blocks by removing one of the screws holding it in place and loosening
the other. Set the cover and screw aside.
b) Install the two 120 VAC 8 AWG power cables (labelled TB13-12 and
TB14-12) onto the upper right-most screw terminal of the TB13 and TB14
distribution blocks. See Figure 3-11 on page 3–14. See the torque
specifications in Table A-8 on page A–6.
c) Put the clear plastic cover back in place over the TB13 and TB14
distribution blocks, tighten the attached screw, and then re-install the
detached screw. Do not over-tighten the screws.
4. Use cable ties or other cable management methods to mechanically secure
the control and power cables so that there will be at least 1 inch of clearance
between these cables and bus bars even after the throat covers are installed.
5. Verify the gasket seals are installed on both flange lips for 360° and that they
have not been damaged. See Figure 3-8. If they have been damaged or are
not installed, contact customer service and do not proceed.
6. Use a provided M5 socket head cap screw with star washer to secure one
end of the ground cable to the ground bus bar in the inverter (TB7), and then
torque to the specification provided in Table A-7 on page A–6. See Figure 3-
13 and Figure 3-14 on page 3–16.
7. The ground cable will be connected to the top throat cover and the throat
covers will be installed during commissioning in “Verify Throat Connection Kit
Wiring” on page 4–4.
