1.4 Instruction for compliance with UL Mark (UL require-
ments), U.S. and Canadian electrical codes
Short circuit ratings
ADV200 WA inverters must be connected to a grid capable of supplying a sym-
metrical 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 motor power rating (Pn mot in the manual) are shown
in the table below.

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 specified in par.
Optional external fuses”, page 117
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 specified in par.
“5.1.1 Cable Cross Section”, page 26.
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 300 sec for time.
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.
