5 INSTALLATION HINTS
Installation the motor controller in a specific vehicle may vary from what is
presented here or include additional steps. It is the responsibility of the vehicle
manufacturer to develop detailed instructions for installation and maintenance of
the motor controller in the target vehicle.
The motor controller contains no user adjustable or user replaceable
components beneath its protective cover. Do not remove the cover.
Do not clean the motor controller using high-pressure water.
Wiring errors, improper setup, or other conditions may cause the vehicle to
move in the wrong direction or at the wrong speed.
Take necessary precautions to prevent injury to personnel or damage to
equipment prior to applying power for the first time.
The instructions in this chapter are general-purpose procedures that do not
address vehicle-specific requirements. Personnel performing maintenance should
consult the vehicle manufacturer's instructions, which always supersede the
instructions in this document.
5.1 Material overview
Before starting the inverter installation, it is necessary to have the required
material for a correct installation. Wrong choice of additional parts could lead to
failures, misbehaviors or bad performance.
5.1.1 Connection cables
For the auxiliary circuits, use cables of 0.5 mm² section.
For power connections to the motor and from the battery, use cables having
proper section. The screwing torque for the controller power connection must be
comprised in the range 13 Nm ÷ 15 Nm. For the optimum inverter performance,
the cables to the battery should be run side by side and be as short as possible.
5.1.2 Contactors
Main contactor has always to be installed. The output driving the coil is
modulated with a 1 kHz PWM basing on parameters MC VOLTAGE and MC
VOLTAGE RED.. After an initial delay of about 1 second, during which the coil is
driven with a percentage of VBATT defined by MC VOLTAGE, PWM reduces the
mean voltage down to the percentage set in MC VOLTAGE RED.. This feature is
useful to decrease the power dissipation of the coil and its heating.

Questions and answers
Como comprobar el funcionamiento del controlador dualac2 sin display
You can check the operation of the Zapi DUALACE2 NEW GENERATION controller without a display using the following methods:
1. Zapi Smart Console – Connect the Zapi Smart Console to the CAN bus to access diagnostics and parameter settings.
2. PC CAN Console – Use the PC CAN Console software to monitor and adjust controller settings.
3. Self-Diagnosis Feature – The controller performs self-diagnosis, and faults can be displayed using Zapi tools.
4. Alarm History Log – Check the log of alarms to review past faults and system behavior.
5. TESTER Function – Use the TESTER function to monitor key operational readouts.
These methods allow you to diagnose and verify the controller’s operation without an external display.

A brumby electrical truck that has a zapi inv.dace2, records the failure 244 "Warning Slave It depends on the supervisor uc", and the alarm 248 "Mc is Opened, eb is applied". On the other hand, the LED does not turn on, but in the manual I did not find the LED code. I would like more certainty about whether the failure is from the controller and the LED code for this Zapi model.
Failure 244 "Warning Slave" depends on the supervisor microcontroller (µC). No specific effect or troubleshooting steps are provided in the available context.
Alarm 248 "MC is Opened, EB is Applied" indicates that the main contactor (MC) is open, and the electric brake (EB) is applied. This typically occurs during start-up, standby, or other system states.
The LED code for this model is not explicitly provided in the available context.
