The power-supply, direct-current and motor terminals as well as the brake cables and

thermistor cables can carry hazardous voltages even when the converter is out of service.

After interruption of the power supply, wait at least 5 minutes until the device has

discharged itself. Only then carry out installation work.

It is strictly forbidden to isolate the device from the supply on the motor side; isolation from

the supply must always be carried out on the supply side of the converter.

Before the power supply for the converter is connected, it must first be ensured that the

terminal box of the motor has been connected.

This device is designed to ensure internal motor-overload protection in accordance with

UL508C. See P0610 and P0335; i²t has been set to ON as the standard setting.

If an LED or similar indicator does not light up or is not active when a function is switched

from ON to OFF, this does not mean that the unit has been switched off or is current-free.

The converter must always be properly grounded.

The device must be isolated from the power supply before any cables, plugs or wires are

connected to the device or altered.

Make sure that the converter has been configured for the correct supply voltage. It must be

ensured that the converter is not connected to a higher supply voltage.

Static discharge on surfaces or at interfaces which are not generally accessible (e.g.

terminals or connector pins) can cause malfunctioning or defects. The ESD protective

measures should therefore be observed during work with converters or converter

components.

The general and regional installation and safety regulations for working on equipment

carrying hazardous voltages (e.g. EN 50178) as well as the relevant stipulations regarding

the correct use of tools and personal protective equipment (PPE) are especially to be

observed.

CAUTION

Children and other unauthorized persons must be forbidden access to the devices!

It is only permissible to use these devices for the purpose indicated by the manufacturer.

Unauthorized changes and the use of spare parts and accessories which are not sold or

recommended by the manufacturer of the device can lead to fires, electric shock and

injuries.
