Refer to section 2-1-3 in the MX2 User's Manual (Cat. No. I570) for operations

Illustrations are only provided for one Inverter size. The instructions however
are generic, and may be followed for all Inverter sizes. Make use of the
MX2-A@ Inverter manual.
Never operate the Inverter with the terminal block cover or backing plate
removed.
Always connect the grounding cable to one of the ground terminals of the
MX2-A@ Inverter. Failure to abide could lead to serious or possibly fatal injury.
Provide emergency stop circuits, interlock circuits, limit circuits and similar
safety measures in external circuits (NOT in the Option Board). This ensures
safety in the system if an abnormality occurs due to malfunction of the Option
Board or another external factor affecting the Option Board operation. Not
doing so may result in serious accidents.
Never touch the heat sink during or just after operation; it can be very hot.
Be sure that the Option Board is mounted correctly. Improper mounting may
result in malfunction.
Be sure that all cable connector screws are tightened to the torque specified
in the relevant manuals. Incorrect tightening torque may result in malfunction.
