Bitzer 2DES-3.F1Y

KT-210-4 21
3 Technical data
Frequency inverter .F1
Operating voltage 380 .. 480 V ±10% 3 phases (three phase current) 50/60 Hz
Required fuse and contactor se-
lection
Required fuse type gG
Recommended: 25A
Maximum: 32A
If the UL/cUL conformity must be adhered to, back-up fuses of the types Buss-
mann KTSR 500 V or Ferraz Shawmut, ATMR, class CC (max. 30 A) must be
used. The fuses must be designed for the protection of a circuit that can supply
max. 100,000 A (symmetrical) at max. 500V.
Compressor (protection device SE-B1) 4A quick acting
The main contactor (K1) connected upstream of the FI must be equipped with
the "safe stop" function, i.e. the entire compressor-FI unit must be de-ener-
gised when the main contactor is switched off.
