K1. Auxiliary early open contact
Examples:
- Auxiliary contact GAX11 10EA of
the GA series of switches and
breakers, Lovato Electric.
- Auxiliary contact HI11-P1/P3E
061813 applicable to switches and
breakers P1-.../E, .../EA..., .../EZ y
P3-.../E, .../EA, from Moeller.
K2. Auxiliary early open contact
Examples:
- Auxiliary contact HIV in automatic

Moeller.
Note. Observe that having the main switch - S1 closed, although the power contactor - KM1 is open, the internal auxiliary
power supply remains connected to the unit through its connector X1 to feed the control circuits of the drive.

Diagram of the maneuver
Important. The relay - KA3 acts simultaneously upon contact KA3,1 to excite the coil of contactor - KM1 and upon the
auxiliary contact KA3,2 (see previous figure) associated with the PWN ENABLE (pin 4 of X6) of the RPS power supply.
Make sure that the time «t» used to program the off-delay of relay - KA3 associated with contacts KA3,1 and KA3,2 is
greater than the braking time (full stop) to permit returning all the excess energy to mains while braking.
