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.
