Electrical installation

DANGER

There might be dangerous voltages inside the devices and at the terminal strips after the complete axis system has been disconnected from the power supply.
Severe or fatal injuries from electric shock.
To prevent electric shocks:
  • Observe the labels on the devices and the waiting times until discharge of the energy storage units before you start working on the power connections.
  • If you discharge the energy storage units with the discharge unit, observe the information in chapter Discharging the energy storage units using the discharge unit.
  • After maintenance work, do not operate the axis system unless you have remounted the safety covers, because the device has only a IP00 degree of protection with the safety cover removed.

DANGER

A leakage current > 3.5 mA can occur during operation of the MOVIDRIVE® modular application inverter.
Severe or fatal injuries from electric shock.
To avoid shock currents according to EN 61800-5-1, observe the following:
  • Supply system cable < 10 mm2:
    • Route a second PE conductor with the cable cross-section of the supply system cable in parallel to the protective earth via separate terminals or use a copper PE conductor with a cable cross-section of 10 mm2.
  • Supply system cable 10 mm2 – 16 mm2:
    • Route a copper PE conductor with the cable cross-section of the supply system cable.
  • Supply system cable 16 mm2 – 35 mm2:
    • Route a copper protective earth conductor with a cable cross-section of 16 mm2.
  • Supply system cable > 35 mm2:
    • Route a copper protective earth conductor with half the cross-section of the supply system cable.
  • If an earth leakage circuit breaker is used for protection against direct and indirect contact in isolated cases, it must be universal current-sensitive (RCD type B).

NOTICE

Interchanging the poles when connecting a DC source/sink.
The devices will be damaged if you interchange poles while connecting an external DC source/sink to an MDP92A and/or MDC90A.

INFORMATION

Installation with protective separation.
The application inverter meets all requirements for protective separation of power and electronics connections in accordance with EN 61800-5-1. The connected signal circuits and the DC 24 V voltage supply must meet the requirements according to SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low Voltage) to ensure protective separation. The installation must meet the requirements for protective separation.
