U Cautions:

- Live parts in the PFC equipment must not be touched!

- Warning signs in the PFC systems are required!

- Wait 10 minutes after the main switch is turned off – until the voltage in the system has dropped to

an uncritical value.

- In non-detuned systems (400 V grid) capacitors with a higher voltage rating (e.g. 440 V) are

needed.

- In detuned systems (400 V grid) capacitors with a voltage of 525 V are needed.

- For discharging the capacitors, special high-voltage resistors type EW22 are required. Standard

resistors cannot be used!

- In dynamic PFC systems discharge reactors cannot be used! This would be a short circuit of the

high-DC-voltage.

In PFC systems without filter circuit reactors current limiting reactors are required (e. g. BD-100)

for the TSM-LC.

- For short circuit protection, superfast electronic fuses for protection of the thyristor are required,

standard HRC fuses are not suitable:

- 63 A / 690 V (25 kvar) – 3 pieces per module

- 125 A / 690 V (50 kvar) – 3 pieces per module

FAILURE TO FOLLOW CAUTIONS MAY RESULT, WORST CASE, IN PREMATURE FAILURES OR

PHYSICAL INJURY.

U Please read cautions information about PFC capacitors and cautions as well as installation and maintenance instructions in the actual

version of the Product Profile Power Factor Correction to ensure optimum performance and prevent products from failing, and in worst case,

bursting and fire, etc. The actual Product Profile is available at www.epcos.com/publications.

Information given in the PFC-product profile and values given in the data sheet reflect typical specifications. You are kindly requested to

approve our product specifications or request our approval for your specification before ordering.
