Description
To connect three-phase AC input power to the
control circuit.
For 460 V unit: 380 to 460 VAC +10%, -15%,
50/60 Hz +/-5%
To connect precharge/discharge resistor.
When the built-in resistor is used:
Jumper between PR2 and PR3, and open
PR1.
When an external resistor is used:
Connect the resistor between PR1 and
PR2, and open PR3.
When the unit is connected for power
regeneration mode only:
Open all the terminals PR1, PR2 and
PR3.
To be used as the control terminals for the
main magnetic contactor (rated for 250 VAC/
1 Amp or 30 VDC/1 Amp).
