WARNING
Damage to braking resistor - Risk of fire!
You must implement fire prevention measures for the external braking resistor (e.g. fire
protection housing, temperature fuse). The externally connected braking resistor cannot
drop below a value of 2.25 ohms, including all tolerances.
Note
To enable sufficient braking power in all dynamic operating states, a resistance value
<8 ohms is recommended.
