Bypass Balance Transformer Wiring Procedure (Optional)

1.Remove the transformer wiring panels on the SymmetraTM frame, and on the back of the transformer.

2.Move the jumper bar on the frame terminal block up one position. See illustration.

3.Pull the wire through the conduit. Leave enough wire extending from the conduit strain relief to reach terminal blocks.

Note: The input wires must not be in the same conduit as the output wires. See wiring schematic.

4.Attach flexible metal conduit to the SymmetraTM wiring panel and to the transformer frame . Remount the wiring panel onto the SymmetraTM frame.

5.Strip approximately 1/2” (13 mm) of insulation from the end of each wire.

6.Connect the ground wire to the green/yellow grounding terminal block connection.

7.Connect the neutral wires to terminal block connections marked “N” in blue.

8.Connect remaining power wires to terminal block connections.

9.Inspect wiring to ensure proper connections.

Caution!

νFasten connection screws to ensure good electrical connection.

10. Remount the wiring panels onto the

 

 

SymmetraTM frame and the transformer.

 

 

11. Switch the bypass circuit breaker to the on

 

 

(I) position and install the cover plate over it.

 

 

See illustration.

 

 

 

Note: Installing the bypass transformer option

 

 

removes the bypass circuit breaker from the

 

 

power path.
