Never move jumpers when power is
on! It can damage the unit.
The Control Voltage (110 or 220/240 VAC) is
required to power the KW941 as well as to provide a
voltage sample for power computation.
The voltage (VAC) MUST be obtained
from a voltage transformer connected between
two phases of the three phase motor power leads.
If a control voltage transformer (with at least 15 VA
capacity) is already present between two phases, it
can be used to supply the voltage. Otherwise, a
suitable transformer must be installed.
In the case of a 220/240 VAC three phase motor, the
voltage (VAC) can be obtained directly across two of
the phases, provided that the Display/Control module
is set for 220/240 VAC voltage operation.
The control voltage is connected to the KW941
Display/Control module using properly sized wires in
an appropriate conduit. Wire the control voltage
(VAC) to the KW941 terminal strip (TS1) as shown in
Figure 4.3. Table 4.1 describes the function of each
of the terminal strip positions.
