5 Installation BECKHOFF Drive Technology
34 Version : 4.6 AX5000
5.2.1.3 External protection, UL-compliant
Integral solid state short circuit protection does not provide branch circuit protection. Branch
circuit protection must be provided in accordance with the Manufacture Instructions, National
Electrical Code and any additional local codes.
Suitable for use on a circuit capable of delivering not more than 18000 rms symmetrical
amperes, 480 V maximum, when protected by RK5 class fuses.
For alternatives regarding class RK5 UL-fuses, you must observe “UL508 A, chapter
SB4.2.3, exception no. 1”. For further questions regarding UL-fuses, please contact your
responsible certification authority.
