ƒ

Death or severe injuries when touching the terminals.

Protective measures:

ƒ

Before working on the brake resistor disconnect the basic device
from the mains.

ƒ

Check all power terminals for safe isolation from supply.

ƒ

Select the mounting location so that the operating conditions
mentioned in the technical data are always ensured.

}

Danger!

Hot surface during operation

During operation, the brake resistor becomes very hot. (For
temperatures, see Technical data.)

Possible consequences:

ƒ

Severe burns when touching the brake resistor.

ƒ

Fire or smouldering fire if flammable materials or substances are
placed near the brake resistor or may get to it.

Protective measures:

ƒ

Before working on the brake resistor, check its surface
temperature.

ƒ
