AFE200 • Instruction Manual 9
1.4 Instruction for compliance with UL Mark (UL require-
ments), U.S. and Canadian electrical codes
Short circuit ratings
AFE200 must be connected to a grid capable of supplying a symmetrical short-
circuit power of less than or equal to “xxxx A rms (at 480 V +10% V max).
The values of the “xxxx” A rms short-circuit current, in accordance with UL require-
ments (UL 508 c), for each power rating (AFE output in the manual) are shown in
the table below.
Short current rating
AFE output (kW) SCCR ( A ) @480Vac
1,1...37,3 5000
39....149 10000
150....398 18000
299.....447 30000
448-671 42000
672-1193 85000
≥ 1194 100000 ... 200000
Note! Drive will be protected by semiconductor Fuse type as specified in the instruction manual.
Branch circuit protection
In order to protect drive against over-current use fuses specied in par. 11.1.
Environmental condition
The drive has to be considered “Open type equipment”. Max surrounding air
temperature equal to 40°C. Pollution degree 2.
Wiring of the input and output power terminals
Use UL listed cables rated at 75°C and round crimping terminals. Crimp terminals
with tool recommended by terminal manufacturer.
Field wiring terminals shall be used with the tightening torque specied in par.
5.1.1.
Over-voltage control
In compliance with CSA-requirements Overvoltage at mains terminal is achieved
installing an overvoltage protection device as for :
Type OVR 1N 15 320 from ABB or similar.
Minimum time required for safe DC-link voltage
Before removing drive cover in order to access internal parts, after mains discon-
nection wait for time as follow :
Drive size Safe time ( sec )
size 3.....5 300
size 6...7 and Parallels 300
