Fig. 15 Example of connection with a forward and reversing motor starter (contac-
tor).
NOTE: In order to accomplish the above result, it will be necessary for a
forward and reversing motor starter to be installed. See Fig. 15 Example of
connection with a forward and reversing motor starter (contactor).
NOTE: In Fig. 15, R1 and R2 (K1 and K2) must not be energized/on at the
same time as this will generate a short circuit. Therefore it is important
that window 65 = 2 before the relays are connected to the contactors.
