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.
Hot surfaces - risk of personnel injury. After operation of the motor
controller, the heat sink may be too hot to touch. Allow it to cool before
performing any maintenance.
Water sensitive equipment - risk of damage to equipment. Do not clean the
motor controller using high-pressure water.
5.2.2 Dust and liquid ingress prevention
The dust/moisture protection of the motor controller is only valid when the
mating I/O connector is inserted and correctly assembled with appropriate
cable seals.
The motor controller cover provides a measure of protection from liquids and
particles dripping, splashing or spraying onto it. The motor controller must not
be subjected to liquids under high pressure.
5.2.3 Wirings: power cables
- Power cables must be as short as possible to minimize power losses.
They must be tightened onto controller power posts with a torque of
13 Nm ÷ 15 Nm.
- The DUALACE2 New Gen should only be connected to a traction battery. Do
not use converters outputs or power supplies. For special applications please
contact the nearest Zapi Service Centre.
Do not connect the controller to a battery with a nominal voltage different
to the nominal value, indicated on the controller label. A higher battery
voltage may cause failures in the power section. A lower voltage may not
allow the controller to work.
Ring lugs for motor and battery connections must be adequately rated to
carry motor and battery currents. Otherwise cables and terminal posts may
be overheated.
5.2.4 Wirings: CAN bus connections and possible interferences
CAN stands for Controller Area Network. CAN bus is a communication protocol
for real time control applications. CAN bus operates at data rate of up to 1 Mbit/s.
It was invented by the German company Bosch to be used in the automotive
industry to permit communication among the various electronic modules of
vehicle, connected as illustrated in the following image.
