5 Electrical Installation5.1 Warnings for Electrical InstallationDuring electrical installation, observe the relevant local and national regulations in addition to the information in this manual.W A R N I N GLEAKAGE/GROUNDING CURRENT HAZARDLeakage/grounding currents are >3.5 mA. Improper grounding of the MSD 510 system modules may result in death or seriousinjury.- For reasons of operator safety, use a certified electrical installer to ground the system correctly in accordance with theapplicable local and national electrical standards and directives, and the instructions in this manual.W A R N I N GHIGH VOLTAGEThe MSD 510 system contains components that operate at high voltage when connected to the electrical supply network.There are no indicators on the components that indicate the presence of mains supply. Incorrect installation, commissioning, ormaintenance may lead to death or serious injury.- Installation, commissioning, and maintenance may only be performed by qualified personnel.W A R N I N GHIGH VOLTAGEPotentially lethal voltage is present on the connectors that may lead to death or serious injury.- Before working on the power connectors (disconnecting or connecting the cable), disconnect the PSM 510 from the mainsand wait for the discharge time to elapse.5.2 Electrical Environmental ConditionsCompliance with the following electrical environmental conditions is necessary to enable safe and effective operation of the servosystem:• Only for use in TN-S, TN-C, TN-CS, TT (not corner earthed) supply earthing system• Prospective short-circuit current: 5 kA• Protective class I• Grounded 3-phase mains network, 400–480 V AC ±10%• 3-phase frequency 44–66 Hz• 3-phase lines and PE line• External supply for auxiliary voltage, 24–48 V DC (PELV)• AC choke (see 5.9.1 AC Line Choke)• Observe the national statutory provisions.• The leakage current is >3.5 mA.Electrical InstallationOperating Guide | VLT® Multiaxis Servo Drive MSD 510 SystemAQ262450196490en-000101 / 175R1170| 57Danfoss A/S © 2019.10
