Reactive Mode—Reacte: 

Reactive mode provides leading 

or lagging kVAR based on the Reactive Target. React Mode 

does not require the installation of CTs.

Reactive Target

 can be set either based on kVAR or 

amperes. Reactive Target can be set remotely through 

MODBUS 

Load Balancinge: 

When ON, the unit corrects for load 

imbalance (negative sequence current). CTs are required 

when Load Balancing is selected.

Admin password setup

For security purposes, we recommend changing the 

Admin password from the default password. To change the 

password:

1. 

Touch the Password field to open an alpha keypad.

2. 

Enter a new password for the Admin User.
The password must be between 6 and 32 characters 

with any combination of letters or numbers. Passwords 

are case sensitive.

3. 

Enter it again in the Confirm field.

4. 

Press Change Password. Or, if you prefer to keep the 

default password, just press Next.

Test Run

When you initiate the Test Run, the unit operates briefly 

providing data on the unit or system performance.

otee:

N

If this is a parallel system, perform this step after 

all other units in the system have been properly 

commissioned and are ready to run or you might  

see a reduction in performance.

To perform the Test Run, do the following:

1. 

Press Yes.

2. 

Press Start.

When the test run has completed, the unit or system 

performance results are displayed. You should see a 

significant reduction in THDi between Unit On versus 

Unit Off.
