5.1.3 Fuses
-
Use a 10 A fuse for protection of the auxiliary circuits
-
Selection of appropriate fuse ratings is a system design issue and falls under
the OEMs responsibility. As a rule of thumb, the fuse shall be rated based on
the motor controller's power output (2 min. rating) listed in chapter 2.3.
Calculate DC input current as follows:
��
����
Select a fuse with rating and time delay characteristics which will carry ��
indefinitely, but blow within 2 - 3 seconds for 2 x ��
-
Chapter 11 shows the maximum allowable values. For special applications or
requirements these values can be reduced.
-
For safety reasons, we recommend the use of protected fuses in order to
prevent the spreading of particles in case a fuse blows.
-
Selection of appropriate fuse ratings is a system design issue and falls under
the OEMs responsibility.
The fuse is not intended to protect the motor controller or motor against
overloads.
5.2 Installation of the hardware
Before doing any operation, ensure that the battery is disconnected.
Take necessary precautions to not compromise safety in order to prevent
injuries to personnel and damages to equipment.
5.2.1 Positioning and cooling of the controller
Install the inverter with the base-plate on a flat, clean and unpainted metallic
surface.
-
Ensure that the installation surface is clean and unpainted.
-
Apply a light layer of thermo-conductive grease between the two surfaces to
permit good heat dissipation.
-
Ensure that cable terminals and connectors are correctly connected.
-
Fit transient suppression devices to the horn, solenoids and contactors not
connected to the controller.
-
Ensure the compartment to be ventilated and the heat-sinking materials
ample.
-
Heat-sinking material and should be sized on the performance requirement of
the machine. Abnormal ambient temperatures should be considered. In

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.
