1.2 About the controller

1.2.1 Safety

Zapi provides this and other manuals to assist manufacturers in using the motor
controller in a proper, efficient and safe manner. Manufacturers must ensure that
all people responsible for the design and use of equipment employing the motor
controller have the proper professional skills and knowledge of equipment.

The high power levels and high torque available from a motor and motor
controller combination can cause severe or fatal injury.

Before installation, always verify that the motor controller model is correct
for the vehicle's battery supply voltage. The DC Supply nominal voltage is
shown on the motor controller's identification label

Before doing any operation, ensure that the battery is disconnected and
when the installation is completed start the machine with the driving
wheels raised from the ground to ensure that any installation error does not
compromise safety.

After the inverter turn-off, 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 – 100 Ohm between +B
and -B terminals of the inverter for at least 10 seconds.

1.2.2 OEM's responsibility

Zapi motor controllers are intended for controlling motors in electric vehicles.
These controllers are supplied to original equipment manufacturers (OEMs) for
incorporation into their vehicles and vehicle control systems.
Electric vehicles are subject to national and international standards of
construction and operation which must be observed. It is responsibility of the
vehicle manufacturer to identify the correct standards and to ensure that the
vehicle meets these standards. As a major electrical control component, the role
of a Zapi motor controller should be carefully considered and relevant safety
precautions taken. It has several features which can be configured to help the
system integrator meeting vehicle safety standards.
Zapi does not accept responsibility for incorrect application of its products.
