Note 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.
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.
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.
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.
Please adhere to the requirements of section 2-3-2 in the MX2 user's manual
on "Installation Environment clearance". In addition to this, provide sufficient
clearance to allow connection and removal of the PROFIBUS Connector. No
unnecessary strain should be placed on the PROFIBUS cable or connector
that could be transferred to the Option Board.
