Issue:
How to change the power sign on 5.2E, 6.2E, 5.3E,6.3E trip units for Powerpact H, J and L frame breaker?

Product Line:
Powerpact H, J and L

Resolution:
The power sign can be changed through Modbus registers or with RSU software and UTA test kit STRV00910.

RSU:
Modify the Power sign using the RSU software and UTA Tester STRV00910, see link for free RSU download.

In the Metering setup/Power sign window, select the power sign:
• + The power running through the circuit breaker from top to bottom is
counted positively.
• - The power running through the circuit breaker from top to bottom is
counted negatively.
The default value of the power sign is +.


MODBUS:
Power Flow
Sign 3316 3315 RW — — UINT 0–1 E
Power flow sign
0 = the active power flows from upstream (top) to downstream (bottom) (default).
1 = the active power flows from downstream (bottom) to upstream (top).
The power flow sign command (command code = 47240) configures the content of the power flow sign register.

Power flow sign

(default)
1 = the active power flows from downstream (bottom) to upstream (top).
