Ul Certification - KEB COMBIVERT F6 Series Instructions For Use Manual

cerTIFIcATION

6.2 UL certification

Acceptance according to UL is marked at KEB drive controllers with the adjacent logo on
the nameplate.
To be conform according to UL for use on the North American and Canadian Market the
following additionally instructions must be observed (original text of the UL-File):
• All models:
Maximum Surrounding Air Temperature: 45°C
• Use 75°C Copper Conductors Only
• Control Circuit Overcurrent Protection Required
• Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit pro-
tection must be provided in accordance with the Manufacturer Instructions, National Electrical Code and
any additional local codes.
CSA: For Canada: Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the Canadian Electrical Code, Part I.
• Only for use in non-corner grounded type WYE source not exceeding 277V phase to ground.
• For installations according to Canadian National Standard C22.2 No. 274-13:
For use in Pollution Degree 2 and Overvoltage Category III environments only.
• Suitable For Use On A Circuit Capable Of Delivering Not More Than 10000 rms Symmetrical Amperes,
480 Volts Maximum when protected by Class J Fuses, see instruction manual for Branch Circuit Protec-
tion details.
Suitable For Use On A Circuit Capable Of Delivering Not More Than 30000 rms Symmetrical Am-
peres, 480 Volts Maximum when protected by Semiconductor Fuses by SIBA (Type 20 189 20.), or by
Bussmann (Type 170M13), or by Littelfuse (Type L70QS), see instruction manual for Branch Circuit
Protection details.
Details of the prescribed Branch Circuit Protection as specified in the below section 'Branch Circuit Pro-
tection' of this Report need to be marked in the instruction manual.
• WARNING – The opening of the branch circuit protective device may be an indication that a fault current
has been interrupted. To reduce the risk of fire or electrical shock, current-carrying parts and other com-
ponents of the controller should be examined and replaced if damaged. If burnout of the current element
of an overload relay occurs, the complete overload relay must be replaced.
• Brake resistor ratings and duty cycle:
• Duty cycle 50%
• Max. 60 sec on-time / 60 sec off-time
