# 6. Wiring diagram
k, I: leads of the current trans-
former
L2, L3: 2 of the 3 phases
M1, M2: leads of the normally
open alarm contact
A: output relay common source
1-12: outputs
# 7. Leads connection
7.1. Push the lever of the connec-
tor with a screwdriver.
SWITCHING STRATEGY
Reactive power requirement is calculated based on average reactive
load during a switching delay time (minimum 40 sec.).
RVC decides on the number of steps based on above and switches on
the biggest step first to avoid intermediate switching. During this
switching sequence, a fixed 12-second delay time between each step is
introduced in order to avoid transient problems and to fulfill EMC re-
quirements. The default switching is circular (# 8.) which increases life-
time of capacitors/contactors.
MODES
AUTO mode (default)
RVC decides on the number of steps required to reach the target PF
based on user setting (target PF, C/k, ...)
Display of cos j, Vrms, Irms, THDV, THDI. (refer to 10.1)

MAN mode

This mode allows the user to control the power factor manually.
Display of cos j, manual switching of steps. (refer to 10.2.)

7.2. Insert the wire in the corre-
sponding connection hole while
keeping the pressure on the lever.
7.3. Release the screwdriver.
7.4. The wire is properly con-
nected.
If the connections (CT and volt-
age) are done properly, the RVC
will display the PF measurement
screen, in the Auto mode (refer to
# 10.). Note: wire size ≤ 2.5 mm²
