Application
This procedure is to uninstall BAYAH120VKTand convert 5TEM6/A5AHV unit to factory configuration. With these steps customers can use 208/230V field supply to power up the AHU.
Installation Instructions for Converting the unit back to 208/230V
Prerequisite before converting the unit to 230V:
- Use 230/24V Transformer that was retained earlier during 120V conversion. If it is not available/damaged, the same can be ordered by TRR01557 at Trane part store.
- Use Jumper that was retained earlier during 120V conversion. If it is not available, the same can be ordered by WIR13810 at Trane part store.
- Use Male 6–pin polarized plug-Red and Black, that was retained earlier during 120V conversion or the Male 6-Pin polarized plug from heater, for heater installation.
Follow the steps below to convert the 5TEM6/A5AHV units with 120V conversion kit to a standard 208/230V primary, 24V secondary transformer operating unit.
-
Disconnect the power supply of the unit.
-
Remove the Front Blower Panel to get access to the Control Panel.
-
Remove the screw that attaches Control Board (MCB) to the frame.
-
Rotate the Control Board (MCB) clockwise to get access to the backside of the controls.
-
Disconnect the male6–pin polarized plug with White and Black wire from the unit.
-
Disconnect the Line Choke terminals from the Red wires.
-
Disconnect the Blue wire from one end and Blue & Green/ Yellow wire (Crimped Together in one terminal) from the other end of the Ground Terminal.
Note: Refer Wiring Diagram (Figure 2) for detailed wiring information. -
Disconnect the Red 24V Wire from35VA 120/24V Transformer and the Red Wire of the unit Harness (From Fuse).
Note: Refer Wiring Diagram (Figure 2) for detailed wiring information. -
Disconnect the High Voltage Harness (Black and Red) wires from the Primary side terminals of the 35VA 120/24V Transformer.
-
Connect the harnesses removed from 35VA 120/24V Transformer to 230/24V Transformer (High Voltage & Low Voltage Terminal). Also, remove the Ground Terminal.
-
Connect back the retained Jumper to its position as shown in figure and Wiring Diagram.
Note: Refer Wiring Diagram (Figure 1) for detailed wiring information. -
Once all the harnesses are connected to 230V/24V transformer, unscrew the 35VA 120/24V Transformer and Line Choke from Heater Knock-out Plate.
-
Connect the Male 6–pin polarized plug with Red and Black wire to the female 6–pin plug or connect to the Male 6-Pin polarized plug from heater, if heater to be installed.
-
Re-attach the Control Box (MCB) to the frame using the screw that was removed earlier in the Step 3.
-
Remove the 120V Adapter Harness for Motor.
-
Directly plug—in the High Voltage Harness (Red and Black) male connector to the motor as shown in Remove 120V Adapter Harness from Motor.
**Unit Connection with BAYAH120VKT
**
- Secure back the Front Blower Panel.
- Remove the 120V conversion label from the Front Blower Panel and the unit is now ready for the 230V field application.
