Start-up procedure

WARNING
The converter is at a hazardous voltage level even when the line contactor is open. The gating
board (board mounted directly to lower part of housing) has many circuits at hazardous voltage
levels.
Non-observance of the safety instructions given in this manual can result in death, severe
personal injury or substantial property damage.
NOTE
The start-up procedure described below applies in situations where the SIMOTRAS HD converter is
connected to the system in accordance with the suggested connection plan. If this is not the case,
additional or other measures may be required in certain instances.

1) PTC thermistor according to DIN 44081 / 44082 with specified R at rated response
temperature. When a PTC thermistor is selected as the temperature sensor, it is not
necessary to set parameters P491 and P492 (alarm and trip temperatures). These two
temperatures are predetermined by the type of PTC thermistor installed. Whether an alarm or
fault is output when the operating point of the PTC thermistor is reached depends on how the
relevant input is parameterized (P493.F or P494.F).
P491 Alarm temperature (factory setting = 20°C)
