Figure 3.13 Bypass Panel Conduit Entry Diagram
Run input power, motor wiring, and control wiring in three separate conduits for isolation.
NOTE!
IMPORTANT NOTE
RUN INPUT POWER, MOTOR WIRING AND CONTROL WIRING IN THREE SEPARATE METALLIC CONDUITS OR RACEWAYS FOR HIGH FREQUENCY NOISE ISOLATION. FAILURE TO ISOLATE POWER, MOTOR AND CONTROL WIRING COULD RESULT IN LESS THAN OPTIMUM DRIVE AND ASSOCIATED EQUIPMENT PERFORMANCE.

The drive always resides in the upper section of the panel. Connections to the ECB and EMB2 are in this area except on the P2 bypass panels.
Power connections are typically towards the bottom side of the panel.
Control wiring should be isolated from power components inside the unit as much as possible. Trane has included hardware to allow for the separation.
