1.4 Instruction for compliance with UL Mark (UL requirements), U.S. and Cana-
dian electrical codes
Elevator Accessory
The UL/cUL mark applies to products in the United States and Canada.
This drive is evaluated in accordance with ASME A17.5-2011 4th Ed. 2011-03-01 Clause 19.4 and CSA B44.1-11 and ASME A17.1-2010 19th Ed. 2010-12-
30 Clauses 2.26.4.1 and 2.26.4.2 and CSA B44-2010 .
Also evaluated in accordance to United States Standard for Power Conversion Equipment, UL508C 3rd Ed. and Canadian National Standard for Industrial
Control Equipment, C22.2 N°.14-13 12th Ed.
Short circuit ratings
ADL300 inverters must be connected to a grid capable of supplying a symmetrical short-circuit power of less than or
equal to “xxxx A rms.
The values of the “xxxx” A rms short-circuit current, in accordance with UL/CSA requirements (UL 508 c, C22.2 N°.14-
13), for each motor power rating (Pn mot in the manual) are shown in the table below.
Short current rating
Pn mot (kW) SCCR ( A )
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 case of 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.....5 300
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.
