W A R N I N G

SHOCK HAZARD

The unit can cause a DC current in the PE conductor. Failure to use a Type B residual current-operated protective device (RCD)

may lead to the RCD not providing the intended protection and therefore may result in death or serious injury.

When an RCD is used for protection against electrical shock, only a Type B device is allowed on the supply side.

-

Overcurrent protection

•

Extra protective equipment, such as short-circuit protection or motor thermal protection between drive and motor, is required
for applications with multiple motors.

•

Input fusing is required to provide short circuit and overcurrent protection. If not factory-supplied, the installer must provide
fuses. See maximum fuse ratings in 8.7.2 CE Compliance and 8.7.3 UL Compliance.

Wire type and ratings

•

All wiring must comply with local and national regulations regarding cross-section and ambient temperature requirements.

•

2.

Depending on the configuration of the equipment, connect the input power to the mains input terminals or the input dis­connect.

3.

Ground the cable in accordance with the grounding instructions, see 4.3 Grounding and 4.5.1 Grounding the Cable Shield.

4.

When supplied from an isolated mains source (IT mains or floating delta) or TT/TN-S mains with a grounded leg (grounded
delta), ensure that parameter 14-50 RFI Filter is set to [0] Off. This setting prevents damage to the DC link and reduces
ground capacity currents in accordance with IEC 61800-3.

4.7 Control Wiring

•

Isolate the control wiring from the high-power components in the drive.

•

When the drive is connected to a thermistor, enusre that the thermistor control wiring is shielded and reinforced/double insula­ted. A 24 V DC supply voltage is recommended.

4.7.1 Safe Torque Off (STO)

To run STO, additional wiring for the drive is required.
Refer to the VLT® Frequency Converters Safe Torque Off Operating Guide for further information.

equipment

Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers residing on the in­put power side of the drive, or output side to the motor. Ensure that they are ready for full-speed oper­ation.

Check the function and installation of any sensors used for feedback to the drive.

Remove any power factor correction capacitors on the motor.

Adjust any power factor correction capacitors on the mains side and ensure that they are dampened.

Cable routing

Ensure that the motor wiring and control wiring are separated, shielded, or in 3 separate metallic con­duits for high-frequency interference isolation.

4.7.2 Mechanical Brake Control

In hoisting/lowering applications, it is necessary to control an electro-mechanical brake.

•

Control the brake using any relay output or digital output (terminal 27 or 29).

•

Keep the output closed (voltage-free) as long as the drive is unable to keep the motor at standstill, for example due to the load
being too heavy.

•

Select [32] Mechanical brake control in parameter group 5-4* Relays for applications with an electromechanical brake.

•

The brake is released when the motor current exceeds the value in parameter 2-20 Release Brake Current.

•

The brake is engaged when the output frequency is less than the frequency set in parameter 2-21 Activate Brake Speed [RPM] or
parameter 2-22 Activate Brake Speed [Hz], and only if the drive carries out a stop command.

If the drive is in alarm mode or in an overvoltage situation, the mechanical brake immediately closes.

N O T I C E

The drive is not a safety device. It is the responsibility of the system designer to integrate safety devices according to relevant

national crane/lift regulations.
