Single-axis controllers Wiring Safety notes for the installation according to U L or U R 4 4.6 4.6.2 Device size 8S ... 10 Warnings! ƒ Branch circuit protection: Suitable for use on a circuit capable of delivering not more than 100000 rms symmetrical amperes, 500 V max., when protected by the specified fuses ( Tab. 4.6-1). ƒ Voltage of the fuses must at least be suitable with the input voltage of the drive. ƒ The integral solid state protection does not provide branch circuit protection and that branch circuit protection has to be provided externally in accordance with manufacturers instructions, the National Electrical Code and any additional codes.
ƒ For information on the protection level of the internal overload protection for a motor load, see the corresponding Application Manuals or Software Helps. ƒ For information on rating and proper connection of the thermal protector (only for connection to motors having integral thermal protection), see the corresponding Application Manuals or Software Helps. ƒ Maximum surrounding air temperature: 55 °C with derating. ƒ Use 75 °C copper wire only, except for control circuits. ƒ Control card protection: External fuse for 24 Vdc supply voltage of control terminal X2. Rated 4 A DC fuse UL248-14. Tab. 4.6-1 ƒ 100 kA SCCR with above fuses.
