When AC voltage is CAP013DG 1000 V disconnected, CAPZero automatically discharges the X capacitor by CAP004DG 825 V connecting the series discharge resistors.

CAPZero If lower dissipation or lower voltage across each resistor is required during fault tests, the total external resistance can be divided into more discrete resistors, however the total resistance must be equal to that specified in Table 1. Safety CAPZero meets safety requirements even if placed before the system X Capacitor input fuse. If a short-circuit is placed between D1 and D2 terminals R1 of CAPZero, the system is identical to existing systems where CAPZero is not used. With regard to open circuit tests, it is not possible to create a fault condition through a single pin fault (for example lifted pin test) since there are two pins connected to each of D1 and D2. If several pins are lifted to create an open circuit, the condition is identical to an open circuit X capacitor discharge resistor in existing systems where CAPZero is not used. If redundancy against open circuit faults is required, two CAPZero and R1 / R2 configurations can be placed in R2 (cid:31)≥4 mm parallel. Discharge Operation To meet the safety regulations, when the AC supply is disconnected, CAPZero will discharge the X capacitor to the safety extra low voltage (SELV) levels according to the above functional description. Although there are no specific safety requirements below SELV, CAPZero still PI-5610-041310 continues the discharge until the X capacitor is fully discharged. As such CAPZero can be safely used at low input voltages such as the Figure 4.
