Braking Resistors - High Temperatures
Braking resistors can reach high temperatures. Locate braking resistors so
that damage cannot result. Use cable having insulation capable of
withstanding high temperatures.
Braking Resistors - Overload Protection
It is essential that an overload protection device is incorporated in the
braking resistor circuit. This is described in section 5.1.1 Thermal
Protection Circuit for an Optional Braking Resistor.
3.1.1 *Input current
The input current values given could be exceeded where the supply fault current is
greater than 5kA or the phase voltages are not balanced. In these cases, input line
reactors are recommended. See section 4.4.3.
3.1.2 **Temperature effects on inrush currents
Due to the design of the inrush circuit, the inrush current will be lower on the first power
up of the Drive after a period of non-use and when the Drive is cold. The inrush current
will increase when the time between power ups is short and the internal ambient
temperature within the Drive is high.
3.2 General data
IP Rating.
If the Drive is not mounted in this way, hazardous live parts will be exposed
and the IP Rating of the Drive will be invalid.
