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.
