Connecting the dynamic braking resistor
The dynamic braking resistor is a potential free stainless steel heating resistor.
The 2 terminals of the resistor connect to the 2 power terminals X1/
B.
The kit shown on the picture consists of the resistance with a 200°C temperature
sensor (opening contact), a protection grid and mounting accessories.
It is mandatory to connect the temperature sensor to the external interlocks to avoid
overheating of the resistance (risk of fire) in case of breakdown of the braking
chopper (short-circuit).

Contact opens at 200°C
The 2 wires of the temperature sensor
connect to terminals X2/39 and X2/40. The 2
wires have to be protected against
accidental contact with the braking resistor
as the temperature of the resistor could
damage the insulation of the wires
OPTIONS: Temperature sensor rated at lower level than 200°C. The required
temperature must clearly be specified on order. The unit will get a
specific part number.
