4.2 Installation of the hardware
U
Before doing any operation, ensure that the battery is disconnected and
when all the installation is completed start the machine with the drive
wheels raised from the floor to ensure that any installation error do not
compromise safety.
After operation, even with the Key Switch open, the internal capacitors may
remain charged for some time. For safe operation, we recommend that the
battery is disconnected, and a short circuit is made between Battery
Positive and Battery Negative power terminals of the inverter using a
Resistor between 10 ohm and 100 ohm.
4.2.1 Positioning and cooling of the controller
Install the inverter with the base-plate on a flat metallic surface that is clean and
unpainted.
-
Apply a light layer of thermo-conductive grease between the two surfaces to
permit better heat dissipation.
-
Ensure that the wiring of the cable terminals and connectors is carried out
correctly.
-
Fit transient suppression devices to the horn, solenoid valves, and contactors
not connected to the controller.
-
The heat generated by the power block must be dissipated. For this to be
possible, the compartment must be ventilated and the heat sink materials
ample.
-
The heat sink material and system should be sized on the performance
requirement of the machine. Abnormal ambient air temperatures should be
considered. In situations where either ventilation is poor, or heat exchange is
difficult, forced air ventilation should be used.
-
The thermal energy dissipated by the power block module varies and is
dependent on the current drawn and the duty cycle.
4.2.2 Wirings: power cables
-
The power cables length must be as short as possible to minimize power
losses.
-
They must be tightened on controller power posts with a Torque of 13-15
Nm.
-
The inverter 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.
-
During battery charge, disconnect the controller from the battery.
-
Never connect SCR low frequency chopper with AC Motor Inverter because
the Rail capacitors alter the SCR choppers' work. If it is necessary to use two
or more control units (tr lift. for ex.), they must belong to the
ZAPIMOS family.
U
Do not connect the inverter to a battery with a nominal voltage different
than the value indicated on the controller label. A higher battery voltage
may cause power section failure. A lower voltage may prevent the logic
operating.
