Completing the Installation 1. Using a utility knife or pliers, cut free the opening on the drive cover to clear the control wiring conduit. 3. Remove the existing bypass labels on the inside of the bypass cabinet door and replace with new labels provided in the Migration Kit. 4. Close the bypass enclosure door and secure. 5. Reconnect power. Bypass Parameter Settings Figure 1. Trim Cover to Match Conduit. 2. Mount the BT300 Drive cover and tighten the screws. 1. Change Ctrl Signal 2 A (3.5.1.2) to a value of DigIN Slot0.1 (virtual off). This removes the reverse command from DI2. 2. Change Run Interlock 2 (3.5.1.13) to a value of DigIN SlotA.2 (use Digital Input 2). This is used to monitor the M2 Contactor. 3. Change RO2 Function (3.5.3.2.4) to a value of FaultInvert. This is for fail-safe operation of fault relay (wired to normally closed contact). If the inverter loses power but the bypass does not, then the contact closes to indicate to the bypass that there is a problem. The installation is now complete.
