• Output range: 24 V DC ±10%• Maximum current: 1 AUse a 24 V supply unit that is CE marked for industrial use. Ensure that the supply fulfills the PELV specification and is only used for thesystem safety input.A common supply for auxiliary and safety supply can be used, provided the only connection point of the 2 circuits is near to the supply.This is intended to avoid interference due to a common voltage drop. The maximum cable length between the 24 V supply unit andthe servo system is 3 m.The safety supply can be looped from PSM 510 to the other MSD 510 system components except for ACM 510, which does not have anSTO connection. The cable for this is not provided. For further information, see 8.6 Installation.N O T I C E- Ensure reinforced isolation between safety signals and other signals, supplies (mains supply), and exposed conductiveparts.5.7 UL RequirementsN O T I C E- Integral solid-state short-circuit protection does not provide branch circuit protection. Branch circuit protection must beprovided in accordance with the National Electrical Code/Canadian Electrical Code, and any additional local codes orequivalent.- Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical amperes, 480 V maximum whenprotected by maximum 80 A class J or T fuses.- To meet the UL (Underwriters Laboratories) regulations, use a UL-approved copper cable with a minimum heat-resistanceof 60 °C. Use Class 1 wire only. For PSM 510 rated 30 kW, use a maximum heat resistance of 75 °C.- Control Circuit Overcurrent Protection is required.Electrical InstallationOperating Guide | VLT® Multiaxis Servo Drive MSD 510 SystemAQ262450196490en-000101 / 175R1170| 63Danfoss A/S © 2019.10
