B. Annex B
B.1 CE-Marking
CE marked frequency inverters and servo drives were developed and manufactured to
comply with the regulations of the Low-Voltage Directive and EMC directive. The harmonized
standards of the series EN 61800-5-1 and EN 61800-3 were used.
This is a product of limited availability in accordance with EN 61800-3. This product may
cause radio interference in residential areas. In this case the operator may need to take
corresponding measures.
The inverter or servo drive must not be started until it is determined that the installation
complies with the Machine directive as well as the EMC-directive (note EN 60204).
B.2 UL Marking
Acceptance according to UL is marked at KEB inverters with the adjacent
logo on the type plate.
To be conform according to UL for use on the North American Market the following
instructions must be observed (original text of the UL-File):
• For control cabinet mounting as „Open Type“
• „Only for use in WYE 480V/277V supply sources“
• Operator and Control Board Rating of relays (30 Vdc.: 1 A)
• Maximum Surrounding Air Temperature 45 °C (113 °F)
• Overload protection at 130 % of inverter output rated current (see type plate)
• Motor protection by adjustment of inverter parameters. For adjustment see
application manual parameters Pn.14 and Pn.15.
• „Use 60/75°C Copper Conductors Only“
• Terminals - Torque Value for Field Wiring Terminals, the value to be according
to the R/C Terminal Block used.
• Use in a pollution degree 2 environment
• ”Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with the
Manufacturer Instructions, National Electrical Code and any additional local
codes”, or the equivalent”.
