0
Not limit for use of DB resistor
Warning
Take caution when DB resistor is used over its Watt rating.
Fire may result from resistor overheat. When resistor having
heat detection sensor is used, sensor output can be used as
external trip signal in multifunction input.

ED is limited as the setting in H76.
H76: set the resistor operating rate (%ED) in one sequence of operation.
Continuous usage rate is Max 15 sec and usage signal is not issued over 15
seconds.
The inverter capacity varies with DB resistor; please refer to Page 13-5.
For 230V inverter, when DC link voltage rises to the value set in F73, the DB resistor is
activated.
