CONNECTION
When using the circuit shown in Figure 4-3, it is
necessary to connect terminals and to the
hot side of the MC Contactor.
CAUTION: Do not to make the RO and TO
connections. If not made, continuous of the
MC Contactor occur under certain conditions
that will stress (or fail) the resistor and DC link
capacitors.
AC LINE REACTOR CONNECTION
An AC Line Reactor is required on inverters
if the rating of the supply transformer is greater
than the horsepower rating of the inverter or
500 KVA (whichever is greater). This reactor is con-
sidered optional and must be purchased separately
when required for specific applications (see “Op-
tions’ paragraph in Section 2).

DC REACTOR CONNECTION
A DC Reactor is required on all inverters
rated 100 HP and above. This reactor is included in
the purchase of the inverter and shipped with the
inverter. This reactor must be installed or the war-
ranty will be voided.
1. Remove the jumper between the and
terminals (installed at factory).
2. Connect DC Reactor between these terminals as
shown in Figure 4-4 (see TABLE 3 for wire sizing).
