Safety instructions for damping resistors for HFD reactors
Risk of burns due to high surface temperatures of the damping resistor
The damping resistor can become very hot. You can get seriously burnt when touching the
surface.
• Mount the damping resistors so that contact is not possible. If this is not possible, attach
a clearly visible and understandable warning notice at hazardous positions.
• To prevent adjacent components from suffering damage due to these high
temperatures, maintain a clearance of 100 mm on all sides of the damping resistors.
Preferably mount the damping resistors outside of the control cabinet.
