Important Warning
Carefully follow the wiring instructions provided in the Power Connection section of the User Manual.
The information on this datasheet is only a summary.
Mandatory Connections
It is imperative that the controller is connected as shown in the above diagram in order to ensure a safe and
trouble-free operation. All connections shown as thick black lines line are mandatory. The controller must be
powered On/Off using switch SW1on the PwrCtrl input. Use a suitable high-current fuse F1 (check table 10) as
a safety measure to prevent damage to the wiring in case of major controller malfunction.
Emergency Switch or Contactor
The battery must be connected in permanence to the controllerās Vmot input via a high-power emergency
switch or contactor SW2 as additional safety measure. The user must be able to deactivate the switch or
contactor at any time, independently of the controller state.
Electrostatic Discharge Protection
In accordance with IEC 61000-6-4, Roboteq Motor Controllers are designed to withstand ESD up to 4kV touch
and 8kV air gap. This protection is implemented without any additional external connections required.
Some speciļ¬cations, such as EN12895, require a higher level of protection. To maximize ESD protection, up to
8kV touch and 15kV air gap, you may connect the metallic heatsink of the controller to your battery negative
terminal. See App Note 062918 for example connections.
