4 MBL1xxx Motor Controller Datasheet Version 1.2. December 25, 2013

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 trou-

ble-free operation. All connections shown as thick black lines line are mandatory. The controller must be powered

On/Off using switch SW1on the Power Control tab. Use a suitable high-current fuse F1 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 tab 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.

Precautions and Optional Connections

Note 1: Backup battery to ensure motor operation with weak or discharged batteries, connect a second battery to

the Power Control wire/terminal via the SW1 switch.

Note 2: Use precharge 1K, 0.5W Resistor to prevent switch arcing.

Note 3: Insert a high-current diode to ensure a return path to the battery during regeneration in case the fuse is

blown.

Note 4: Optionally ground the VMot input when the controller is Off if there is any concern that the motors could

be made to spin and generate voltage in excess of 30V (MBL1330) or 50V (MBL1660).

Note 5: Beware not to create a path from the ground pins on the I/O connector and the battery minus terminal.
