For recommended mounting practices see section 5.1.2 Mounting Location Selection.
The maximum torque that can be applied to the power lugs is 18 ft./lbs.
The approximate current capacity of the mVEC is 200 A, but that is dependent on the application, type of load, etc.
The mVEC is designed to communicate on a J1939 compliant CAN bus. Refer to section 5.1.6. CAN Connection for more details about connection limitations.
