4.3.5 Temperature monitoring of the braking resistor
4.3.5.1 Terminals R-T1, R-T2
NOTICE
Connect the safe separated temperature switch at the input of the charg-
ing unit.
Thermal contact (NC contact)
minimum switching current: 2 mA

NOTICE
If no braking resistor is required, a bridge must be installed between
R-T1 and R-T2 to evaluate the input, otherwise there is no precharging
and modulation.
