ADV100 • Quick installation guide - Specifications and connection 7
1.4 Instruction for compliance with UL Mark (UL requirements), U.S. and Cana-
dian electrical codes
Short circuit ratings
ADV100 inverters 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 requirements (UL 508 c), for each motor
power rating (Pn mot in the manual) are shown in the table below.
Short current rating
Pn mot (kW) SCCR ( A ) @480Vac
1,1...37,3 5000
39....149 10000
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. 5.1.
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. 7.1.1.
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 disconnection wait for time as follow :
Drive size Safe time ( sec )
size 1.....4 300
Over-speed; over-load/current limit; motor overload
Drive incorporate over-speed, over-current/current limit, motor overload protection. Instruction manual specify degree
of protection and detailed installation instruction.
