7 INSTALLATION SUGGESTIONS AND

PRECAUTIONS

Read and respect the following suggestions to avoid problem during installation

and in the definitive releasing.

7.1 Thermal consideration

- 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.

7.2 General suggestion

- 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 (traction + lift. for ex.), they must belong to the

ZAPIMOS family.

- Do not connect the inverter to a battery with a nominal value different from

the value indicated on the chopper plate. If the battery value is greater, the

MOS may fail; if it is lower, the control unit does not "power up".

- During battery charge, disconnect the controller from the battery.

- Supply the controller only with battery for traction; do not use a power supply.

- When the inverter is installed, make tests with the wheels raised from the

ground, in order to avoid dangerous situations due to connection errors.

- After the controller is switched off (key off), the Rail capacitor remains

charged for some minutes; if you need to work on the inverter, discharge

them using a 10Ω ÷ 100Ω resistance connected from the +Batt to the –Batt

terminals in the controller side.

- Fit transient suppression devices to the horn, solenoid valves, and contactors

not connected to the chopper such as those for activating the pump motor or

steering motor.

7.3 Susceptibility and electromagnetic emission

Electromagnetic susceptibility and emission are strongly influenced by the

installation. Special attention must be given to the lengths and the paths of the

electric connections and the shields. This situation is beyond ZAPI's control.

Therefore ZAPI declines any responsibility for non-compliance if correct testing is

not made (the irradiated emission directive is EN50081-2).
