- Selection of appropriate fuse ratings is a system design issue and falls under
the OEMs responsibility.
U
The fuse is not intended to protect the motor controller or motor against
overloads.
5.2 Installation of the hardware
U
Before doing any operation, ensure that the battery is disconnected.
U
For traction applications, raise up or otherwise disable driving wheels to
prevent the possibility of unexpected vehicle motion or motion in the wrong
direction during initial commissioning. For hydraulic applications, open the
valve to prevent the possibility of excessive pressure (in the event of a
malfunction of the pressure-relief valve).
U
Take necessary precautions to not compromise safety in order to prevent
injuries to personnel and damages to equipment.
U
After operation, even with the key switch open, the internal capacitors may
remain charged for some time. For safe operation onto the setup, it is
recommended to disconnect the battery and to discharge the capacitors by
means of a resistor of about 10
Ω – 100 Ω between terB and -B of
the inverter.
5.2.1 Positioning and cooling of the controller
Install the inverter with the base-plate on a flat, clean and unpainted metallic
surface.
-
Ensure that the installation surface is clean and unpainted.
- Apply a light layer of thermo-conductive grease between the two surfaces to
permit good heat dissipation.
- Ensure that cable terminals and connectors are correctly connected.
- Fit transient suppression devices to the horn, solenoids and contactors not
connected to the controller.
- Ensure the compartment to be ventilated and the heat-sinking materials
ample.
- Heat-sinking material and should be sized on the performance requirement of
the machine. Abnormal ambient temperatures should be considered. In
situations where either external ventilation is poor or heat exchange is
difficult, forced ventilation should be used
- Thermal energy dissipated by the power module varies with the current
drawn and with the duty cycle.
