11. In preparation for testing the Bypass, observe the trip setting of the Circuit Breaker. The trip point is factory 

set at the lowest possible setting and must be adjusted for each application. This breaker will trip due to 
inrush current and load inertia unless it is reset!
•

For fan applications adjust the trip setting to ten times motor FLA.

•

For pump applications adjust the trip setting to six times motor FLA.

If Circuit Breaker tripping is experienced at these settings during motor starting on Bypass, increase the set-
ting gradually until the motor can be started without Circuit Breaker tripping.

12. Press the 

OFF

 key and press the 

BYPASS

 

Select

 key. The Drive will ramp the motor to zero speed, then the 

control will be transferred to Bypass mode. Be prepared to monitor the rotation direction of the motor in 
Bypass operation. “Bump” the 

HAND

 key and quickly press the 

OFF 

key. Check the motor rotation. Do not 

allow the motor to continue operating in Bypass mode until rotation is correct!

If the rotation direction in Bypass is correct, skip the rest of this step. If not, carry out the following correc-
tions:

1.

Turn 

OFF

 the incoming power feed to the E7B unit. Since the correct rotation in Drive mode was 

previously established, do not change any output wires at the motor.

2.

Instead, verify that power is 

OFF

. Then swap the wires for 

L1

 & 

L2

 on the input side of the Disconnect

 

Switch or Circuit Breaker. This will effect rotation in Bypass operation only. Once connections are 

 

complete and tight, reapply the incoming power and repeat the previous step to re-check the rotation

 

direction in Bypass mode.

13. Run the motor in Bypass by pressing the 

HAND

 key. Record all the phase voltages and currents at this time.

14. Press the 

OFF

 key and press the 

DRIVE Select

 key. Press the 

HAND

 key and press the 

DATA/ENTER

 key, 

then scroll the Speed Command to “60 HZ” operation. Monitor the voltages and currents in each of the out-
put phases at full speed to make sure that the voltages are balanced and that the currents are within the motor 
nameplate rating during accel, stable speed, and decel.

15. If this application requires the Drive to operate in PI mode, see Chapter 5 of TM.E7B.01.

For serial communication, refer to Appendix D in TM.E7B.01 or TM.E7.21 (APOGEE FLN) and TM.E7.22
