points is 10 kW to 990 kW, in steps of 10 kW. The Trip
Unit display is shown in Figure 33.

Power Direction Setup
This function selects the normal power flow direction for
the breaker, either from line to load or from load to line.
Figure 34 shows the setup display for normal power flow of
line to load. This direction setup also affects the sign of the
normal power metering displays.

load.
Power-Reversal Relay Delay
This function sets the delay time before a power-reversal
trip occurs. The range of delays is 1 to 15 seconds, in steps
of 1 second. Choosing
OFF disables power-reversal protec-
tion. The Trip Unit display is shown in Figure 35.

Rating Plug Current Setting
The Trip Unit display for rating plug setting is shown in
Figure 36. Enter the current setting of the rating plug by
scrolling through the list with
VALUE and pressing ENTER
when the correct value is reached. Table 15 lists the avail-
able rating plugs for the various Trip Units.
CAUTION: Incorrect storage of this set point will result in
incorrect metering values.
ATTENTION: Si une valeur incorrecte est enregistrée
pour ce réglage, les mesures seront fausses.

Potential Transformer Primary Voltage
Enter the primary voltage rating of the potential trans-
former, as illustrated in Figure 37. The range of values is
120 to 600 volts, with an increment of 1 volt.
CAUTION: Incorrect storage of this set point will result in
incorrect metering values. Even if this setting is entered
remotely, it must be entered again locally.
ATTENTION: Si une valeur incorrecte est enregistrée
pour ce réglage, les mesures seront fausses. Cette valeur
doit être enregistrée locallement même dans le cas d’une
utilisation à distance avec commnet.
