Below is a list of the relevant chapters that are amended with respect to the UL-Listing.
Furthermore, UL-specific remarks are listed. It is essential to observe these specifications.
3.3.1 UL-specific chapter changes
“5.2.1 Mains supply connection (X01)”
AX5000 shall be connected only to a grounded wye-source where the
maximum voltage does not exceed 277 V to ground.
“5.2.3 Connection of several servo drives to form a drive system”
Drive system with UL-Listing!
Please note the configuration example in chapter 5.2.4
3.3.2 UL-specific chapter
“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.
