1) The continues output power is on the 6A device limited to 70%. see Output_Power_638A
2) With S1 full load operation > 1,1KW a linechoke with uk >= 4% is recommended.
e.g. E12-0018KL.
3) Recommended: UL listed (JDDZ) Fusible cut-out Class K5, Class H, Class J, Class CC or
rather UL listed (JDRX) Class H.
4) Recommended e.g. EATONr
5) Class gRL fuses combine protection for cable and semiconductors.
e.g. Fa. SIBA Sicherungs-Bau GmbH
Serie 60 034.34.16; Fuseholder 5106304.x (up to 30A)
Serie 50124.34.xx, Fuseholder 5105804.3 (up to 40A)
If these fuses are used, the mains voltage may only be switched on, when the Softstart -
function is active. (Device in Undervoltage operating state).
6) With S1 full load operation > 5,5KW a linechoke with uk >= 4% is recommended.
e.g.Parker E31-0018KL and for UL-Recommendation Block LR3 40-4/16.
7) UL listed (JDDZ) Fusible cut-out Class J or Class CC.
For DC-Link Applications Class CC Types are recommended.
If Class CC Types are used, the mains voltage may only be switched on, when the Softstart -
function is active. (Device in Undervoltage operating state)
