Energy storage available in bus caps:
EP202: 15 J @ 240 Vac, 30 J @ 120 Vac
EP204: 24 J @ 240 Vac, 63 J @ 120 Vac
EP206: 40 J @ 240 Vac, 104 J @ 120 Vac
EP204/EP206 External Shunt Control:
12 A peak, 2 kW max average power, 33 ohm minimum external resistor
Earth Leakage Current and RCD
Compatibility
25 mA AC and < 0.1 mA DC with 15 ft (4.6 m) CMDS motor power cable and NT-330
motor at 240 Vac. Leakage is higher with longer cables.
The EP drive is compatible with a Type A Residual current Detector (RCD) that allows
expected leakage currents.
