rent protection.
m Z Requirements for the motor temperature sensors – from page 170
n Observe the connecting data of the motor temperature sensor.
cUL notes Additional only for Canada:
NOTE
Overvoltage Protection Device have to be installed in front of the input circuit of the
device to limit the maximum overvoltage peak to 2.5 kV.
