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 Useoflinereactorson page 26.
3.1.2 **Temperature effects on inrush currents
Size1-4
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.

IP Rating
NEMA Enclosure Rating
WARNING
WARNING
Size 1: IP20
The Ingress Protection rating is applicable to the drive when
the supplied rubber grommets are fitted into the gland plate.
Sizes 2, 3 & 4: IP20
The Ingress Protection rating is applicable to the drive when
the supplied rubber grommets are fitted into the gland plate
and the drive is mounted on a solid flat surface.
Size 5: IP00 - Gland plate not fitted
IP10 - Gland plate fitted, cable glands not fitted (unused holes
covered)
IP20 - Gland plate fitted, cable glands fitted (blanking caps
covering unused holes)
Size 1: The drive has a NEMA 1 enclosure rating when a suitable
