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
tab. Use a suitable high-current fuse F1 (check table 12) 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 controller’s Vmot tabs 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 specifications, 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.
