INVERTER
Heatsink Protrusion Attachment
<FR-A7CN01 to 14>
Thank you for selecting the Mitsubishi Electric inverter option unit.
This instruction manual gives handling information and precautions for use of this equipment. Incorrect handing might cause an
unexpected fault. Before using the equipment, please read this manual carefully to use the equipment to its optimum.
Please forward this instruction manual to the end user.
This attachment allows approximately 70% of the heat generated by the inverter (high power factor converter) to be radiated outside the
enclosure by protruding the inverter (high power factor converter) heatsink section out from the rear side of the enclosure.
1. Preparation
1) Confirm the attachment model.
2) Confirm that the following parts are enclosed with the indicated quantity.
*1) For the FR-A7CN05 to 14 lower installation frame, use an inverter (high power factor converter) frame by changing its' installation position.
*2) Use inverter (high power factor converter) screws.
3) Applicable model
Safety Precautions
While power is ON or for some time after power-OFF, do not touch the inverter (high power factor converter) and attachment as they will be
extremely hot. Doing so can cause burns.
The product must be transported in correct method that corresponds to the weight. Failure to do so may lead to injuries. Take special care
with the edge sections.
Do not allow conductive foreign matter such as screws, metal chips, or flammable foreign matter such as oil enter the inverter (high power
factor converter).

NOTE
ï‚Ÿ Having a cooling fan, the cooling section which comes out of the enclosure cannot be used in the environment of
water drops, oil, mist, dust, etc.
ï‚Ÿ Be careful not to drop screws, dust etc. into the inverter (high power factor converter) and cooling fan section.
ï‚Ÿ There is 1mm of clearance between the FR-A7CN and inverter (high power factor converter). (The inverter (high
power factor converter) is not in an enclosed condition)

*1 When carrying the inverter (high power factor converter), do not hold it by the upper frame section of "1) upper installation frame". Doing so
may change the frame shape.
*2 Change the position of the "standard installation foot/lower section" (same as "3) lower installation frame") and screw up both "6) 7) left and
right installation frames".
*3 For the FR-A7CN07 to 11, fit the "2) upper cover" to the "1) upper installation frame" first, and then install the "1) upper installation frame" to
the inverter (high power factor converter).
When installing an "2) upper cover" to the "1) upper installation frame", a gap may sometimes be left between the lower part of the "2) upper
cover" and the "1) upper installation frame". Install the upper cover after making sure that there is no gap.
*4 Place a "8) sticker" before installing the heatsink protrusion attachment. Slits are on the left and right sides of the inverter. Cover the slits on
both sides with stickers. (Sticker placement is not necessary for the high power factor converter.)
