2.2 Residual hazards
{ Danger!
Dangerous electrical voltage
The terminals of the brake resistor may carry dangerous voltages
during operation of the basic device and up to three minutes after
mains disconnection.
Possible consequences:
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 Select the mounting location so that the operating conditions
mentioned in the technical data are always ensured.
ƒ Protect the mounting location by suitable fire prevention and
protection against contact.
