6.3 PWR Module (Power Supply)
The PWR module is a DC/DC or AC/DC converter with electrical insulation between the input and
output. It has an input voltage range as described in the chapter 2. The tolerance of the output
voltage for the electronic components is continuously monitored.
The use of an external miniature circuit breaker is recommended. The miniature circuit breaker
must be in the on position when the device is in operation and in the off position when the device is
in cold reserve. A 6-pin connector is fixed on the PWR module. The pin definition of the
connector is described as below.
